Title: Tilt-Rotor Aircraft
Post by: Jeffry Fontaine on January 08, 2012, 06:08:00 AM
A topic for all tilt-rotor aircraft

I was browsing Jose José Fernandes' latest update in his discussion topic and found myself wondering what a kit-bash between an OV-10 Bronco and the V-22 Osprey would look like.  Retain the booms but lose the engines.  The booms could then be devoted to the landing gear and fuel plus whatever avionics that could not be accommodated in the fuselage proper.  At the wing tips - mount the engines and rotor components from the V-22.  The only thing that I can see at this point that could be a problem is the rotor blade clearance with the tail.  Now I wish I had a 1/72nd scale Italeri V-22 Osprey kit in the stash to check fit with the Testors'/Italeri OV-10 Bronco.

Well, since I now work for Bell, I can say that there were studies for an attack aircraft using Model 609 mechanicals and structure (I saw a rendering over a co-worker's desk).  Meanwhile, I'm more actively involved with developments and projects on the V-22. 

A couple thoughts, since the V-22 is replacing the CH-46 in USMC service, how about a V-22 in three-tone green splinter camouflage replacing the equivalent V-107-II in Swedish service or an OD V-22 with hinomarus doing the same in Japanese service.

Of course, if you're thinking bigger, there's always the Quad-Tilt-Rotor which could be modelled using a C-130 fuselage (alternatively, for grins, use an AN-12 fuselage to get the tailgunner position).

Graeme Davidson did some nice profiles of the V-22 in various schemes for different nations.  One of which was the JASDF and the other was for Sweden in the splinter camouflage.  Since Graeme is not yet a member of this little group any of his work might still reside over on the other forum unless they suffered the recent purge in which case they are gone.

A few of my tilt-rotor whifs for your enjoyment... (I hope).

Grumman OV-1H Mohawk II

(http://fc09.deviantart.net/fs71/f/2011/045/7/1/grumman_ov_1h_mohawk_ii_by_bispro-d39keh1.jpg)

The Grumman OV-1H Mohawk II was the next logical step in the evolution of the reliable and flexible G-134 design. Featuring widened and shortened wings, it became the first operational tilt-rotor in the U.S. inventory when the Army took delivery of the first aircraft in June 1986. The G-134TR Mohawk II proved a valuable asset in difficult missions over Panama and Nicaragua, where the hostile environment made landing impossible to the original version. The Mohawk II was used for observation (OV-1H), as a rescue aircraft (HV-1H) and as an armed counter-insurgencency type (AV-1H). On top of the 110 new examples built by Grumman, most Mohawks remaining in the inventory were overhauled and brought up to "II" standard, bringing the total in operation up to 250. These versions, although externally similar to the new frames, presented a number of technical differences and were therefore designated with the use of the "J" suffix letter instead (OV-1J, HV-1J). There were no AV-1J conversions, as all 60 COIN aircraft were new from the factory. Finally, a small utility transport with deepened fuselage was produced in 12 examples (UV-1K). The last Mohawk II was retired from service in May 2003, making the G-134 family one of the most enduring designs in U.S. service.

Vought V-498 Bluebird VTOL

(http://fc02.deviantart.net/fs71/f/2011/304/5/5/vought_v_498_bluebird_vtol_by_bispro-d4engwq.jpg)

Some may remember my Vought-Sikorsky Shrike (then again you may not... lol). Well, anyway, here is another take on the LTV XC-142 concept, the LTV V-498 Bluebird (which derived its name from Vought's very first aircraft). It was produced in small numbers for a few regional airlines in the U.S. and Canada, such as the now defunct New York Airways, seen here.

Bell-Boeing CV-22C Long Osprey

(http://fc08.deviantart.net/fs70/i/2010/014/0/0/Bell_Boeing_CV_22C_Long_Osprey_by_Bispro.jpg)

The Bell-Boeing CV-22C Osprey is a new transport variant for the US Navy. It can be seen here on take-off trials from USS Harry Truman (CVN-75) in June 2015. The tough part in this picture was not to create the CV-22C from the regular version... it was coming up with a complete picture of the aircraft-carrier's tower! I had to rework it from several pictures...


(http://aviadesign.online.fr/hline.gif)

Boeing-Lear CV-24A Hummingbird

(http://fc00.deviantart.net/fs70/f/2011/197/d/b/boeing_lear_cv_24a_hummingbird_by_bispro-d3wphzd.jpg)

What if Bell/Boeing's V-22 had not been the first operational VTOL? What if Boeing had teamed up with Learjet instead to offer an heir to the old X-19 concept and make it work as a liaison/VIP transport? This is what the fake advertisement above is all about.


(http://aviadesign.online.fr/hline.gif)

And finally a tilt-duct... Not quite what this topic is about, but since someone included a tilt-duct above, I may as well add mine here.


Boeing-Bell XV-16A PLR VTOL

(http://fc00.deviantart.net/fs70/f/2010/303/a/b/boeing_bell_xv_16a_plr_vtol_by_bispro-d31u23u.jpg)

Contrary to popular belief, The V-22 Osprey is not the first joint effort by Bell and Boeing. In 1976, Boeing Vertol teamed up with Bell's Helicopter Division on a proposal for the Army's PLR (Power Lift Rotorcraft) program. Designated XV-16A in the VTOL series, this clean-looking and able performer combined Boeing's experience with transport helicopters and Bell's expertise in VTOL, in this case capitalizing on the tilt-duct research that culminated in the highly successful X-22A prototype a decade before. The PLR program was canceled despite a successful two-year evaluation phase because it was found that its advantages did not outweigh the 35% increase in costs from operating it instead of a conventional Chinook.

This pic below came from the USMC website sometime ago.  I've got a project started to do this but then realized I had gone in the wrong direction so I'm going to start again.  I'm going elaborate on it though as I don't really think having the rear engines behind the front ones like this will be workable (in RW).  Considering that all the engines are interconnected and have shafts running here, there, and everywhere, my idea will be to have two larger engines either side of the fin in an arrangement very similar to the CH-53 instead of the four in the wingtip pods.

Is great bunch of tilt rotor/jet concepts.  Thanks for posting - do like reviewing them.  I have a tilt jet bash on the list to build.  Thinking of doing it STOL using a 30 to 45 degree max tilt.

I was browsing Jose Fern's latest update in his discussion topic and found myself wondering what a kit-bash between an OV-10 Bronco and the V-22 Osprey would look like.  Retain the booms but lose the engines.  The booms could then be devoted to the landing gear and fuel plus whatever avionics that could not be accommodated in the fuselage proper.  At the wing tips - mount the engines and rotor components from the V-22.  The only thing that I can see at this point that could be a problem is the rotor blade clearance with the tail.  Now I wish I had a 1/72nd scale Italeri V-22 Osprey kit in the stash to check fit with the Testors'/Italeri OV-10 Bronco.

You'd like want to do a scalarama with the nacelles from a 1/72 V-22 on a 1/48 OV-10.  The OV-10's engines are rated at no more than 1000-1100 shp max while the the V-22's engines are rated at some 6000 shp.   I could see replacing the OV-10's engines with fairings covering either extra fuel tankage or various equipment fits.  Note that if you do this one, you need to also take the section of the V-22 wing immediately inboard of the engine as there's a lot going on there and some of the wing/engine fairing rotates with the engine nacelles.

That was my intention.  1/48th scale Testor's OV-10 Bronco mated up with a 1/72nd scale Italeri V-22 :^)

As much as I like the idea of "More Power" for the Bronco it would be a challenge to do so with the 48th scale V-22 parts since the blades would conflict in their arcs over the center of the fuselage.  The smaller diameter rotors on the 72nd scale V-22 might work a bit better for what I have in mind.  Just need to find the 1/72nd scale V-22 kit in order to do the check-fit.

Post by: elmayerle on January 10, 2012, 08:35:25 AM
Don't forget that the V-22 is rather larger than the OV-10.  That almost makes such a mixing necessary.  I note that there is one 1/72 V-22 on eBay right now, but it's not cheap at all.

As some of you know, I've done a couple of tilt-rotor creations: a 1/48 "spectre" type gunship and a kitbash of a 1/48 OV-1 Mohawk and a 1/72 V-22 into an escort for the vanilla V-22. 

I've got at least 4 more of the 1/48 Ospreys, only one of which will be done up as a USMC battle taxi.  I have plans to work one up as a US Coast Guard rescue bird with a hoist (or two), inflatable life raft canisters and even a zodiac on the tail ramp ready to deploy. And I love the Canadian SAR profile in yellow with the red stripes down the sides, so that's a definite possibility at some point.   I've seen a suggestion somewhere to make one as a heavy lift bird like the sky crane.

Don't be shy, please share the images of your Ospreys here on the forum as soon as you can. 

I would love to find a 1/48th scale Zodiac.  Have you found a source for one of these or are you going for something smaller in scale like 1/72nd? 

What about a VV-22 As "Marine One"?

Photos will go up tonight for everyone's viewing pleasure.

I'll have to check my laptop at home, but I think I found a 1/48 zodiac from a small AM company, otherwise I might take a shot at scratching one and maybe casting a couple copies?

Ooohhh! A VV-22 would be another possibility - I have the decals from both my CH-46 and CH-53 that are for HMX-1. Add it to the idea list!

So far:
USCG (HV-22?? What would the correct rescue/SAR designator be?)
Canadian SAR
HMX-1

USCG (HV-22?? What would the correct rescue/SAR designator be?)

The official designation of the SAR version was to be HV-22A before it was cancelled, so I guess HV-22C (or whatever suffix) would be okay. This being said, let's keep in mind that the USCG's tendency is to make use of non-standard designations (probably to reflect the fact that the Coast Guard is not a branch of the military in peace time, but a civilian agency). Designations like HV-911 use the manufacturer's number as a designator, MH-68A is (almost) standard, while C-143A and HC-144A take over from the old pre-1962 system. The planned Agusta-Bell BA609 (now the AW609, an Agusta Westland product) for the Coast Guard has been designated the HV-609. A USCG Osprey could also therefore be an HV-901.

I know, I know! It has one of those cool POTUS-only escape pods like Harrison Ford had in Air Force One or the president had in Escape from New York!!!

It would be a cool white-top, though.

LemonJello, just a thought for the HMX-1 VV-22, the CH-53E and, I suspect, the CH-46s, had black tops because they were support aircraft rather than direct transports.  A couple quick and obvious comments on the Vv-22 proposal, it had more windows and the rear ramp was replaced by a set of steps that still closed up the same.  The really tricky bit was modifying the exhausts so that they wouldn't kick up dust and offend powerful persons and there were some "interesting" approaches considered there.

The downwash is pretty bad, compared to other platforms that I've seen/ridden on.  How "interesting" were those approaches?

When I build my VV-22, it'll be a white-top, just because those are cooler. I could see adding windows, would they be larger? But if I go that route I'll tint them since I don't know if I want to spruce up the interior to VIP standards.
Title: Re: Tilt-Rotor Aircraft
Post by: elmayerle on January 14, 2012, 12:34:23 PM
The windows were the same size, just more of them, and the interior was definitely VIP but not overdone.  The "interesting approaches" on the exhausts were different ways of deflecting them outboard, away from the aircraft instead of straight down at the ground.  One such was a diverter system not unlike what Boeing used on the X-32B.

For those looking to do a scaleorama cross of a 1/72 V-22's nacelles with a 1/48 Bronco, I'd recommend the Hobbycraft 1/72 V-22 kit as a suitable donor.  The engine nacelles bear a passing resemblance to the real thing but certainly don't reflect EMD or production configurations; making them highly suitable for whiffing use.

If you slimmed the tip pods down to just the rotor then the roof engines could stay put.

You could follow the line down from the top of the intake to the top of the exhaust outlet.

Regarding an OV-10 conversion, personally I'd have the wing section outboard of the booms
rotate with the new engine/rotor assemblies. The reduction in under disc area would probably
be advantageous in VTOL mode.

D-326 looks like a big brother to what is now the Agusta A609 (formerly Bell-Agusta BA609).  One of the more interesting ones is the D-300 which was an iteration toward what became the XV-15, it looks very much like a long MU-2, with the short MU-2 main gear, with the XV-15 wing (appropriately enough, the Aerophile article on the XV-15 shows that Boeing's entry was based on using a long MU-2 fuselage).  It's a temptation to get the resources together to model that one.

One thing I've always wondered about these is whether they can fire any wing-mounted weapons with the rotors in plane-mode? I bought an Anigrand XV-15 with the intention of bashing it with a lot of AH-1W parts. I'm still wondering how to mount the weapons. Could you fire a Hydra 70, TOW or Hellfire "synchronised" through the rotor?  :o And if you can't, wouldn't it be a terrible waste of energy to have to go into hover mode every time you employ your weapons?
My solution is to use the wing for drop-tanks or bombs only. Anything powered will go on pylons down the fuselage sides, with slightly chopped rotor blades.

Had the chance to go out to the experimental hanger and look over the V-22 we're working on.  It looks like the LH sponson could be stretched forward to fair into the fuselage in line with the windscreen frame; this would give you room for a small weapons bay or fixed gun mount.  There are, too, provisions for a nose-mounted gun turret under the radar but I don't think that option has ever been exercised.

For other possibilities, how about an AEW radar mounted on the aft ramp much like what the FAA has on Sea Kings now?

Ramp mounted radar sounds like the best option considering how low to the ground the aircraft actually sits in real life.  Unless you increase the length of the landing gear to make the room available. 

The stretched sponson sounds interesting.  Or at the very least, an excuse to kit-bash the MatchBox/Revell Chinook with an Osprey.

Yeah, the fun comes on the RH side where you need to work around extended sponson around the main door.  You could probably still do a fairing ahead of that, though, or just mount external stores racks there (being careful to keep clear of the rotor envelope).  I wonder if the Apache's TADS/PNVS turret could be adapted to this use?

I think your best bet would be the issue of Aerophile magazine with the XV-15 as the cover article.  Since said issue is 30+ years old, good hunting.  Methinks your best bet for now would be using a scaled V-22 fuselage and tail (with Kingcobra cockpit and nose) coupled with what's now the AW609's wing and engine nacelles.

Feasible, as long as you're not trying to meet some of the stowage time requirements the V-22 had to meet.  On the other hand, you won't have the same hovering efficiency (that's one thing that's made tilt-wing aircraft expensive - now, a tilt-wing with engine and rotor on the wingtips might be something as long as you don't have that stowage requirement).

Ok, engine and rotor it is. But, for example, for a small strike craft á la gunship or small transport in the league of the Sikorsky S-97 Raider X2 would it be feasible to use propellers the size of those in the XFY-1 Pogo?
Title: Re: Tilt-Rotor Aircraft
Post by: elmayerle on February 06, 2012, 01:02:55 PM
Close enough, if you want a bit bigger, use the props from a 1/48 Pogo on a 1/72 tiltrotor; I have seen some speculation on contra-rotor tiltrotors so there's possibilities there, too.

Figure you're going to want something in the 1000 shp for each engine.  I'm also inclined to suggest a straight-thru engine rather than a reverse flow one like the PT6 as I'm given to understand that the exhaust for this engine on what's now the AW609 is somewhat problem-prone.

That's pretty much the approach I'm planning to take, melding the V-22 wing and nacelle installations to a Dash 8 fuselage and adding sponsons for the main landing gear.  Hmm, that HC V-22 may be a good contributor to this as its engine nacelles are much closer to a civilian design than what the military flies on the V-22.   I've got some bits and pieces that'll make good shapes for the sponsons.

Grumman OV-1H Mohawk II

([url]http://fc09.deviantart.net/fs71/f/2011/045/7/1/grumman_ov_1h_mohawk_ii_by_bispro-d39keh1.jpg[/url])

The Grumman OV-1H Mohawk II was the next logical step in the evolution of the reliable and flexible G-134 design. Featuring widened and shortened wings, it became the first operational tilt-rotor in the U.S. inventory when the Army took delivery of the first aircraft in June 1986. The G-134TR Mohawk II proved a valuable asset in difficult missions over Panama and Nicaragua, where the hostile environment made landing impossible to the original version. The Mohawk II was used for observation (OV-1H), as a rescue aircraft (HV-1H) and as an armed counter-insurgencency type (AV-1H). On top of the 110 new examples built by Grumman, most Mohawks remaining in the inventory were overhauled and brought up to "II" standard, bringing the total in operation up to 250. These versions, although externally similar to the new frames, presented a number of technical differences and were therefore designated with the use of the "J" suffix letter instead (OV-1J, HV-1J). There were no AV-1J conversions, as all 60 COIN aircraft were new from the factory. Finally, a small utility transport with deepened fuselage was produced in 12 examples (UV-1K). The last Mohawk II was retired from service in May 2003, making the G-134 family one of the most enduring designs in U.S. service.

Vought V-498 Bluebird VTOL

([url]http://fc02.deviantart.net/fs71/f/2011/304/5/5/vought_v_498_bluebird_vtol_by_bispro-d4engwq.jpg[/url])

Some may remember my Vought-Sikorsky Shrike (then again you may not... lol). Well, anyway, here is another take on the LTV XC-142 concept, the LTV V-498 Bluebird (which derived its name from Vought's very first aircraft). It was produced in small numbers for a few regional airlines in the U.S. and Canada, such as the now defunct New York Airways, seen here.

Bell-Boeing CV-22C Long Osprey

([url]http://fc08.deviantart.net/fs70/i/2010/014/0/0/Bell_Boeing_CV_22C_Long_Osprey_by_Bispro.jpg[/url])

The Bell-Boeing CV-22C Osprey is a new transport variant for the US Navy. It can be seen here on take-off trials from USS Harry Truman (CVN-75) in June 2015. The tough part in this picture was not to create the CV-22C from the regular version... it was coming up with a complete picture of the aircraft-carrier's tower! I had to rework it from several pictures...

Boeing-Lear CV-24A Hummingbird

([url]http://fc00.deviantart.net/fs70/f/2011/197/d/b/boeing_lear_cv_24a_hummingbird_by_bispro-d3wphzd.jpg[/url])

What if Bell/Boeing's V-22 had not been the first operational VTOL? What if Boeing had teamed up with Learjet instead to offer an heir to the old X-19 concept and make it work as a liaison/VIP transport? This is what the fake advertisement above is all about.


([url]http://aviadesign.online.fr/hline.gif[/url])

And finally a tilt-duct... Not quite what this topic is about, but since someone included a tilt-duct above, I may as well add mine here.


Boeing-Bell XV-16A PLR VTOL

Contrary to popular belief, The V-22 Osprey is not the first joint effort by Bell and Boeing. In 1976, Boeing Vertol teamed up with Bell's Helicopter Division on a proposal for the Army's PLR (Power Lift Rotorcraft) program. Designated XV-16A in the VTOL series, this clean-looking and able performer combined Boeing's experience with transport helicopters and Bell's expertise in VTOL, in this case capitalizing on the tilt-duct research that culminated in the highly successful X-22A prototype a decade before. The PLR program was canceled despite a successful two-year evaluation phase because it was found that its advantages did not outweigh the 35% increase in costs from operating it instead of a conventional Chinook.

I can guarantee that it is not the ESCI/AMT-Ertl kit with the Italeri name on it.  It is an entirely different mold with a better level of details.  As far as emulating the real production version that is an area for which I have no answer.  It used to be a scaled down version of their 1:48th scale kit or the other way around.  They were identical at one point in time but the larger 1:48th scale kit was tweeked to include what were then known modifications to the development aircraft and that is where the two parted company on similarities.  I have both scales in protective custody including both versions of the 1:48th scale kit.

One of the annoying aspects of my present position is that I have access to, but can't share, some interesting items such as one iteration of the VV-22 proposal.  There are some interesting aspects and some that would be a bit more challenging to model, such as more and different cabin windows.
Title: Re: Tilt-Rotor Aircraft
Post by: Jeffry Fontaine on December 19, 2012, 03:52:51 AM
Evan,

Do you have any suggestions on where or how to fit auxiliary fuel tanks to the outside of the aircraft?  Aside from the Esci/AMT-Ertl attempt at creating the SV-22 in 1:72nd scale with some torpedo shapes attached to a very frail looking thing that was supposed to pass for a pair of stores stations mounted on a less than aerodynamic framework.  I have my own ideas for something that would fit on the sponsons with a small wing shape to it to carry a fuel tank but placement so that it is not interfering with the main gear seems to be the problem. 

The easier and obviously and much simpler alternative is to use the fuels cells from the Academy MH-60 Blackhawk and HH-60 Pave Hawk inside the aircraft.  This of course would reduce the capability of carrying anything internally. 

Any suggestions that will not infringe on company secrets?

Convinced a friend of mine to do something similar with the HobbyCraft V-22 using the fuel tanks and pylons from the MH-53 mounted adjacent to the main wheels.  It may have been too much fuel tank but it certainly looked good with the other MH-53 parts added on with the exception of the big chin box holding the radar, FLIR, and refueling boom.  If nothing else actually is possible on the real aircraft then I will probably go that same route again for the 1:48th scale project.  It would be nice to know if that is the same solution that Bell/Boeing would use with the real aircraft in the real world.  The internal fuel cells take up a lot of room inside of the troop/passenger compartment just like they do in the MH-60/HH-60 when installed.  That same space could be put to better use for carriage of personnel and equipment if the fuel carried to extend range is carried somewhere else.

Err, that's something I'm really not at liberty to comment on much because I am aware of what's being studied.  The tanks up forward, as shown on the NH-90,  would have to be positioned carefully lest they get hit by the prop-rotor in airplane mode but I don't believe that's the preferred position.  Similarly, underwing tankage with have to stay clear of the full prop-rotor movement envelope and that could minimze just how large a tank you could put there.  The other thought that occurs to me is to extend the LH sponson as far forward as possible and the RH one up to the door.

Jeffry, I'm unfamiliar with the Exci/AMT SV-22 kit, could you scan the boxtop for me and email it.

Why not some sort of conformal tank which attaches to the front of the main wheel sponsons -- like an extension of the sponson

That was what my friend did with his HobbyCraft Osprey kit and parts from an Italeri MH-53 Pave Low kit that I provided to him for that effort. 

The 600 gallon (2271.247 litre) tanks are a bit large and also a problem to source unless you are flush with lottery winnings.  Since I have the parts available it is no problem for me but I still would like to reaffirm that I was going in the right direction, you know, trying to achieve some level of realism instead of what looks good :)

Evan,

I trashed that kit ages ago.  The kit came with two ladder shaped stores pylons that were to be fixed to a location just above or slightly forward of the main landing gear wells.  The ladder shape was quite plain and slanted towards the front but you can envision a ladder with two rungs at an angle and pretty much get the same shape.  Emil has one at the shop (Skyway Models (http://www.skywaymodel.com/)) but the price is now in the kit collector's range.

IIRC, a variant of the Ospery's engine was pitched as a possible powerplant for the CH-53K but declined in favor of the more powerful GE38-1B... so what if the engine-transfer went the other way, a 15,000SHP Super Osprey?
Title: Re: Tilt-Rotor Aircraft
Post by: elmayerle on December 19, 2012, 10:17:24 AM
Thanks, Jeffry.  Yeah, that's a logical location and, as long as you don't get too long, it keeps stores clear of the prop-rotors.  I wonder, though, why they didn't use a stub wing instead of just an "erector set" rack? (*wink*).

I'm told that the MH-53K engines have been looked at, but considerable redesign would be required to fit them in the Osprey (accessory and drive section) and it's just not cost-effective at the moment.

An extension of the LH sponson for additional tankage is possible while extension of the RH sponson is limited by the presence of the crew door.  There's another approach to conformal tankage under study, but more I can't say.  It's the obvious approach, though.

To fit the CH-53E tanks, you'd need some new structure on the top of the sponsons, including a fairing to extend out and keep the tanks clear of the main gear.

Exactly what my friend Vic Russell did with the HobbyCraft Osprey.  He attached the entire pylon section from the H-53 to include the fairing that attached the entire thing to the sponson on the thing to the Osprey and had it clearing the main landing gear in the process.  It looked convincing enough but the model went MIA in 1989 after it was left behind by accident at a contest held in Evansville, Indiana.

Definitely a cheesy approach to the entire concept with that lazy ladder assembly that AMT-Ertl/ESCI came up with.

Adapting the concept to the realities of how the V-22 goes together (and to workshare between Boeing and Bell) could be interesting; I'm sorely tempted to play with it and see what I can fit together while maintaining existing interfaces.  I would imagine the civil variant could get by without the IR supressors (FWIW, that allows you to use the Hobbycraft nacelles) but with otherwise few differences from the military versions.

I can see prop-tip velocities being an issue with this design, wouldn't take much for them to go way past supersonic.

Wonder if a 4-engined tilt-rotor design is workable? Maybe with the inner engine nacelles extended ahead of a (more) forward canted wing to reduce interference with/by the wing?

I'd hazard a guess that engine and transmission design would probably be the main factor since your two tilting nacelles are going to need the power of the four engines the C-130 normally has.  That's either two very large engines (perhaps a pair of A400M engines?) or two engines coupled to one transmission.  In either case, the transmission is going to be a major effort to handle that much power as well as the control inputs that proprotors require; this would not be an insignificant challenge.

Actually a four engine tilt rotor with either twin engine nacelles or even one engine in each nacelle an another in clutched into the cross linking drive shafts with contra props on each nacelle could be used for a 1/72 to 1/72 Spartan tilt rotor.

Good idea, save that underwing stores firing forward are very likely to hit the prop-rotors and that's not a good thing.  The fuselage-mounted or sponson-mounted approaches look best.  *wicked cackle*  You don't want to see some of the stranger V-22 proposals (scarily enough, at least one looks to be proceeding to test and evaluation).

Now that's a beautiful whif.  I'm not certain how efficient those rotors would be, they look on the short side to me (to be honest, I understand that the V-22 sacrificed some rotor efficiency to get a quickly stowable design).

The engines don't pivot, the rotors do. The engines are mounted on the wingtips.
It's an alternative layout that's been around for decades. Bell proposed it on their
CTR-7500 large civil tilt-rotor. See page 3 of this thread for more.

Boeing used it on their proposal for the XV-15 demonstrator.

I've become concerned with an issue: Tilt-rotor footprint.
With wing and proprotor folding for stowage everything looks well and good; but, what happens when the time comes to spotting planes on deck with fuel burning and rotors turning?
What happens when engaged in operations among urban canyons, say, in support of MOUT?

I've attached the only three comparison images I could find of size comparisons. Note the footprint comparison against the Frog, and the one against the Chinook (specially leghtwise)

V-22 is being evaluated for the COD role to replace C-2A's.  It meets the main criteria, it can carry a crated JSF engine.  More to the point, once it delivers to the carrier, it can then make further deliveries to the rest of the task force without transferring material to a waiting MH-60R or MH-60S.  It's also been trialed, dry, as a refueling bird and has been successful in safely deploying the drogue to where a F/A-18 could mate with it.  I still want to do a USFS one with a mini-MAFS and a hover tank refill capability like the SIkorsky/Aero Union Firehawk has.

Nope, not me, I don't drive a pickup, even if I do live in Texas.  I find it amusing that, as we finally have a good 1/72 V-22 kit out there, we (Bell) are getting ready to make significant changes to the engine nacelles.  The proof of concept for one change is already fiying on N404TR and I'm "assholes and elbows" into the production version.  There's a similar change being studied at the back end, but that's a ways down the road for flying the PoC version (I was heavily involved in that, too).

"Interesting" is quite the word I'd used since I've been dealing with them (at least in the sense of "don't intrude into this swept volume" way, structure does need to clear) and I'd hate to think about the complications contra-proprotors would introduce.

Looks plausible, somewhat like an XV-3 converted to turboshaft power instead of a piston engine.  The only thing I'm not certain of is whether you could fit the controls for four-bladed prop-rotors in those nacelles (they tend to be rather large-sized due to control loads).

It's more of a joke idea, but the 20th SOS flies CV-22B's for AFSOC and their nickname is "The Green Hornets"; it would think that one with the pilot's name shown as "Britt Reid" would be amusing (that, of course, is the name of the radio, and, later, TV, character who fought crime as "The Green Hornet".

Those of us at Bell wouldn't mind that at all!  Meanwhile, there are already three different FMS packages in work and more in negotiations (two of the in-work ones have been reported in the press).  It certainly doesn't hurt that the ATTR is demonstrating design improvements and enhanced capabilities (the IFR capability being just one).

Yes, that's the aircraft on which we are flying the proof of concept for the new inlet on the port engine (I was heavily involved in that and I'm now very heavily involved in the production version).  N204TR is officially the ATTR (Advanced Technology Tilt-Rotor) aircraft and is on bail for demonstrating new developments and technologies.  If you saw pictures of the demo for adding a tanker capability, it was used for that among other efforts that I can't discuss.

ESCI *(AMT/Ertl) had a variation on the V-22 theme that included some odd looking racks for a quartet of even stranger looking torpedo shapes.  The only different between the standard ESCI V-22 Osprey and the ASW version was the decals and that extra portion of sprue with the torpedos and stores racks.

You're not the only one.  I'm looking ot add dipping sonar, sonobuoy dispensers, and a deploable MAD "bomb".  Definitely need better looking torpedos, though.  I'll probalby replace the existing racks with something derived from SIkorsky ESSS pylons.

I was looking at using the UH-60 Black Hawk ESSS parts for that same purpose.  Not quite sure where to apply them though.  A friend of mine back in Indiana built an MV-22 with Pave Low features that included the external fuel tanks and pylons from the MH-53 that were attached on the sponsons just above the main gear on the Osprey.  They really looked good at the time and along with a few other bits and pieces from the Pave Low bird that were attached to the top and bottom of the fuselage and a nice coat of dark green overall it looked quite convincing. 

Most of the parts you require for an ASW Osprey could be sourced from one of the Lynx HAS, Sea King, Sea Hawk, or, Sea Sprite kits that have the parts included for the ASW mission.  The dipping SONAR and the deployable MAD sensor being two of the most common parts in most cases.  If you are wanting some kind of radome affixed to the Osprey you have a couple of choices on location.  Add it on as an extended nose as suggested in the image above?  Perhaps under the fuselage as flown on the Sea Sprite and Sea Hawk LAMPS birds?  On top of the fuselage or attached to the rear loading ramp?  Plenty of options on the location just need to make it fit in with the rest of the concept. 

Decent torpedo shapes in 1:72nd scale are out there and some decent looking Mk 46 ASW torpedoes can be found in the Hasegawa P-3 Orion kit.  Revell's Breguet Atlantic kit also has a couple of nice torpedo shapes and some nice life raft containers if you want to add something uniquie to your ASW bird to give it an SAR mission.  There are a number of other 1:72nd scale kits out there with some torpedo shapes that might work but it all depends on how much detail you want on the things.  I really do not know of any resin or metal aftermarket torpedoe shapes that are currently available.  Anyone have additional information on that to share, please do.  I have some of the following in my possession and I can say that they exceed my expectations for details on amu 1:48th scale torpedo: 
 offers a set of three different torpedo types for the Lynx HAS as [url=http://www.belcherbits.com/lines/148conv/bb34.htm]BB-34 - Lynx ASW Weapons set (http://www.belcherbits.com/Belcher Bits[/url) provides some nice aftermarket resin torpedoes for the Lynx in the form of the Mk 46, Sting Ray, and, Euro Torp MU90. 
AeroBonus (AiRes) (http://www.aires.cz/en/) has a nice set of Mk 44 ASW torpedoes (http://www.aires.cz/en/product/mk-44-us-navy-torpedoes/0-696/) and Mk 46 ASW torpedoes (http://www.aires.cz/en/product/mk-46-us-navy-torpedoes/0-673/). 

Interior details for an ASW V-22 can be found in the same Lynx, Sea Sprite, Sea King, and, Sea Hawk kits though in most cases it is very sparse on the details in 1:72nd scale.  Sonobouy launchers and sensor consoles being the most important pieces.  I would guess the best location for the sonobouy launcher on the Osprey would be on the rear loading ramp or perhaps launched through the floor (underside) of the Osprey.  You could drill some holes for your sonobouy tubes and box it over on the interior to make something that could pass for the launcher system.  In 1:48th scale Osprey you have the same Lynx HAS, Sea Hawk and Sea Sprite kits to source for parts plus the Cobra Company resin conversions for the Sea Sprite and Sea Hawk.  Cobra Company (http://cobracompany.com/) offers the following items for the SH-2 Sea Sprite and the SH-60 Sea Hawk that could be applied towards your SV-22 Osprey ASW aircraft in 1:48th scale:

SH-2 Sonobuoy Launcher (http://cobracompany.com/48063.htm)
SeaHawk External Sensor (http://www.cobracompany.com/48059.htm)
SH-60B Super Detail Set (http://www.cobracompany.com/48026.htm) includes a pair of torpedo shapes plus the sensor console equipment and the sonobouy launcher.  Additional exterior details for the fuel tank sponsons and pylons plus the folding main rotor parts. 
SH-60F Super Detail Set (http://www.cobracompany.com/48027.htm)Pretty much the same parts as above.  Really can not determine what the difference is between them based on the images provided. 

These following items are included just in case you want to adapt some of the parts to your V-22 Osprey:
HH-60H Conversion/Detail Set (http://www.cobracompany.com/48032.htm)
HH-60J "Jayhawk" USCG conversion/ Detail set (http://www.cobracompany.com/48033.htm)
MH-60L conversion for Academy UH-60L (http://www.cobracompany.com/48031.htm)
MH-60L DAP weapons set (http://www.cobracompany.com/48034.htm)

If you don't want to spend the money for the Belcher Bits and AeroBonus torpedoes there is always the alternative of using some of the lesser quality torpedo shapes from the various kits that include an ASW torpedo in the kit. 
Title: Re: Tilt-Rotor Aircraft
Post by: elmayerle on November 04, 2014, 07:29:50 AM
I'm thinking the ESSS rack-derived bits at roughly where the SV-22 kit has that ladder-looking rack; that puts the torpedos well clear of the prop-rotors when they drop.  My plan is to replace the existing lower aft ramp with a sonobuoy launcher mounting the winch for the MAD "bomb" on top of it.  I've got both SH-2 and SH-60 kits in 1/72 to optain the MAD bomb from and I've got a PV-22 kit (same manufacturer(s) as the SV-22) with a dipping sonar.  I'm not totally sure what to do for the radar, but I've time to puzzle that out; real world V-22 efforts are keeping me quite busy.

I'll admit, though, that I like the idea of the radar in the nose rather than under the fuselage; less chance of FOD damage.

Aircraft is N204TR (CN D0043), also known as the ATTR (Advanced Technology TiltRotor). and it's used as a testbed.  This was a "quick and dirty" trials installation that included replacing the standard FLIR turret with one incorporating designation capability.  A production mod would have pylons on both sides and they would be slightly swept forward so that the starboard weapons would clear the door.  The overall location looks peculiar but makes sense in that it moves the weapons out of the sweep of the prop-rotor even in forward flight.

The engine nacelle nearest the camera still has the proof of concept EIBF installation I was involved with on 2011 & 2012 and it's more than demonstrating its worth.  I'm currently involved in a production kit development of this concept.

I've heard rumors that some of these pictures were taken by Jay Miller, but I can't verify at the moment.  I do know there were at least five separate cameras tracking the tests.

I didn't think the rotor arcs were that close to the fuselage?   It's an interesting position for weapons pylons.  Reminds me of the Rockets installed on the Coastal Command Liberators, which were also a cheek installation.

I just had a question pop into my head (don't know where from).  Can the V-22 lower it's nacelles to below the horizontal at all?   I can't really think if it would be any use, except for mid-air braking but I was just wondering...

Yes, they are that close, it really shows when the V-22 is in "show pose" with the nacelles down and the rotors stopped in an "inverted-Y" position.

No, horizontal is as far down as the nacelles will rotate.

Somewhat amused that the drawing is not taken from an accurate side view.  There's an "elephant ear" scoop" for the oil cooler on the upper aft outboard side of the engine nacellee that is quite prominent, but not seen in this art.  Still, the decals themselves look most excellent and add another whif possibility to the two Japanese schemes Hasegawa is producing.

Bell can but hope that all three comes true (some form of Japanese will, the FMS paperwork has already started).

That's true, although the image they use is cropped and facing the wrong way.  No Greg I have that pic all the way from Sept 2008 that's similar but not exact. Hmm, puzzling.


Anyway, in my search I stumbled across something, I saved a Wikipedia entry regarding Dale Brown's fictional aircraft, specifically the MV-32.

"The MV-32 is the advanced version of the V-22 tilt-rotor aircraft. The traditional propellers found on the V-22 are replaced by advanced jet engines. It fires navalized versions of the FIM-92 Stinger and has two cannon pods, with a 20 mm Gatling gun under the nose. The MV-32 has enhanced range and speed over the V-22 and is traditional used in Tin Man support operations."

So Jet lift?
Instead perhaps some form of Un-ducted fan? or like an extended/enlarged A400M / An-70 style prop?

Can the transmission handle more than three blades thereby reducing the prop/rotor arc?
Or attach the wing to a different fuselage.
Or even search through the whole thread an see what else had been posted.

GTX' posted a fan-jet V-22 earlier in this discussion at this link: Reply #44, 20120107 from Greg T (GTX_Admin), Re: Tilt-Rotor Aircraft (http://beyondthesprues.com/Forum/index.php?topic=298.msg3217#msg3217)

Based on that idea I dabbled around with a jet engine (fan-jet) version of the V-22 based on a digital model I found at the SketchUp 3D Warehouse (https://3dwarehouse.sketchup.com/?redirect=1) several years ago.  Since the model was derived from the work of another party I did not share it on-line.  I do have some screen captures of the model I made in an image gallery attached to my FB page.  Here are a few of the images that I uploaded to that gallery:

While the transmission likely could, the control linkages eat up volume like you wouldn't believe (I'm dealing with that area as part of the project I'm on and I have to be careful to stay out of the volume they rotate through).  I know there've been studies of dual contra-rotating prop-rotors, but I don't know of anything that progressed to flight test status.

I know the Bell tilt-rotor thread over on Secret Projects has a depiction of a Bell/Boeing proposal of the V-22 nacelles and wing mated to a Dash 8 fuselage with a sponson added, each side, for the main gear.  I intend to model that one, either in civil markings or in CAF markings.

You'll need to extend the span on the wings. I know because I had one half built, Italeri V-22 + Hobby craft Dash 8, it died after a shelf collapse a couple years back.

Odd thought for a huge tilt-rotor aircraft, a MIL Mi-12 with just the transmission and proprotor moving for each nacelle.

This thought stemmed from the NASA Historical Monograph on the XV-15 which include a lot of back history on tilt-rotor aircraft.  Platt-LePage Helicopters got into it looking at improvements that could be made to the Focke-Angleis twin-rotor concept with horizontally-spaced rotors rather than fore-and-aft spaced ones.  Since the Mi-12 has this same configuration, it seemed a natural as a large tilt-rotor aircraft.

Firmly on my to do list is a tilt rotor strike version. V-22 wings and rotors with a minimalist fuselage with hard points underneath for rocket pods, Hellfire and such. Some form of gun perhaps like the Apache. Landing gear would have to be on the tall side to allow room for weapons loading.

Seems IIRC the Marines have the problem of the V-22s out running their helicopter escorts. Usually its the armed aircraft out running the transports.

One reason an armed V-22 demonstration has been conducted.  The real trick is keeping the released weapons clear of the proprotors.  My own thought would be to keep the existing lines but replace the cargo bay with a weapons bay with doors on the bottom.

I as thinking Apache simply because Boeing acquired the Apache during their merger mania and has kept it.  Granted that the design office for the Apache is rather far across the country from the design office that did the fuselage of the V-22 (just outside Philadelphia), they still could work together.

With both in 1/72, you'd need to redo most of the rest of the V-22 fuselage.  I'm thinking a 1/48 Bronco to a 1/72 V-22 would work, though.  Have to check that out.

Has anyone said how they are going to deal with the F-35 engine cans? My understanding is that it doesn't fit into a V-22 cargo bay.

The V-22 cargo bay has a published width of 65" and the F135 has a diameter of 46". 19" is not much of an allowance for a shipping can and a transport pallet.

Awkward, but it would be possible to ship the can only (assuming it fits), but a bit tight. They must have a plan to support the F-35 during a COD mission, anyone have any details?

I couldn't quite see why the USN would consider the V-22 as a COD if it couldn't carry the F-35 engine shipping cradles.  They must have known it was capable of doing it well before hand. 

I couldn't understand one of the detractors comments that it wasn't capable of carrying the weight of them either, he said the Greyhound could bring on-board 5 tons of cargo, the specs for the V-22 say it can carry 20,000 lb internally, well that '10' tons --- much more capable I'd think --- and take it to any ship with a landing pad to boot.

Don't start getting facts crossed up with other peoples delusions. Somebody ends up with a stroke from the high blood pressure.

Did a little checking. The payload for the V-22 was listed by Wikipedia as 20,000 lbs and the C-2 at 10,000 lbs. The two aircraft had about the same cruising speed but the C-2 had a much longer range. Of course the V-22 has AAR capability and, as you said, can land on any ship with a landing pad. So sacrifice range for versatility. Unless you have a COD with intercontinental range the fleet is going to have to sail close to a friendly base that has the supplies it needs anyway.

A V-22 COD also helps if you've got carriers without arresting gear; your only other option, then, is a much slower CH-47 or something equivalent.

I wonder why I couldn't find those images when searching?

Kind of a minimalist engine can, but it is a can and an engine goes inside... then it all goes inside an Osprey.

The V-22 as a support for fleet ops is a good choice. I've often wondered why it wasn't in place for VERTREP. I can see lots of potential for supporting dispersed forces. I wonder if they will start building flightdecks on AORs to handle the extra weight? Logistics are critical, anything that improves the flow is a good thing.

If memory serves me correctly, she was a derivative of the design for H.M.S. Lion and I've seen drawings of a studied battlecarrier version of that design, so you'd have a starting place for this conversion of Vanguard.

(Does it seem ironic to anyone that the last British battleship built was named "Vanguard"?)

yup.

I sometimes think people confuse real issues and actual trade offs and decisions with minor gripes that are not deal breakers. I noticed that seems to be the thing a lot of these articles lock onto. Much like a successful marriage, work and adjustments and annoyances are not deal breakers, I wouldn't divorce my wife because she chews her food too loud when she has fried chicken. people have a hard time differentiating between a serious concern and some detail that needs to be accounted for, but the all other aircraft have those too. There are no perfect weapons.

Some of these gripes are just relics leftover from times before a lot of the complainers were even born, I'm still seeing complaints about the F-15 being "too complex" its amazing.

Anywho, I am hoping this is the start of more US Navy use, from ASW to SAR, even Naval Special Warfare. Vertical lift is never short of work.

I assume Alvis mean the Flying Dorito, because that's the one I meant and the CIA bird was actually a success rather than being cancelled before its first flight.  Not the place to discuss but I have wondered how close it was to actually working and if it could have been made a success, there are a whole raft of whiffs in the projects cancelled by Cheney then Rummy when he got his turn as SECDEF.

If you don't have the storage height requirement the USMC wanted, you could probably do it fairly easily, though the connnections when the wings pivoted to the stowed position might be a pain.  It's probably the cleanest approach but, if you're working with that restriction, such as a variant that could be shared with the USMC or other users, it gets a bit more problematical.

An enlarged nose radome might fit, getting decent side arrays given the sponsons and the blockage the tilted nacelles would give in hover mode, I'm not sure how practical such an approach would be.

Another tilt-ducted fan:

(http://www.aerospaceprojectsreview.com/blog/wp-content/uploads/2015/04/Bell-D190B-VTOL.jpg)

The description with this is very enticing for whiff ideas:

"...an artists impression of the Bell D190B, a tilt-duct VTOL derived in part from the X-22. The D190 series, dating from the early 1960’s, was for a more-or-less common airframe design that could carry out a number of missions. Interestingly, variants of this design were considered for “parasite” roles. The aircraft could hard-dock to the underside of a C-130; the larger transport aircraft could then haul the smaller VTOL around the world, where it could serve as a rescue plane (note the rectangular hatch on the top of the fuselage). Another idea was for the small VTOL to serve as a crew or passenger transfer system for EC-135J (707 derivatives) flying command posts, including transporting VIPs (read: politicians) away from nuclear strikes to orbiting escape planes."

Something I've been thinking about.  Is there a reason why all the tilt-rotors are three-bladed rather than four or more bladed?  I have an idea in the back of my mind and am unsure about how many blades I should put on the rotors...

Partly it's a matter of the controls you can fit into a nacelle of comfortable size (the V-22 nacelle is just packed, very little extra room) and still have robust control rods etc.  Perhaps Fly by Wire may change this in the future, but for the present three seems to be pretty much optimum.

FWIW, here's the explanation of what happened to that MV-22B that crashed in Hawaii: http://breakingdefense.com/2015/07/fatal-crash-prompts-marines-to-change-osprey-flight-rules/ (http://breakingdefense.com/2015/07/fatal-crash-prompts-marines-to-change-osprey-flight-rules/)

The EIBF shown is the prototype "Proof of Concept" version I was involved with from mid-2011 to mid-2012.  I've been involved with the production version since mid-Spetember, 2013; it's more "maintainer friendly" than either the PoC or present inlet and EAPS and it does eliminate some of the problems the earlier version had.  If one was going to model it, the Hasegawa 1/72 kits are the only ones I'd recommend using as their nacelle construction would make modelling the new configuration easier.  Now, when this goes forward, I hope someone does a conversion kit (I keep thinking of an Italian one with the new inlets, painted in "sand and spinach" camouflage and operating in North Africa).  Oh, FWIW, the basic concept here is very similar to the "tropical" filter installed on Bf109s and MC.202s.

*wry chuckle* We can hope, though.  We feel we have a very good product and we are aggressively addressing the known shortcomings.

I do know that the USMC has found that the V-22 has allowed them to greatly disperse forward deployed ships without complicating logistic support, making it far more difficult for anyone to target them.  It should be most interesting to see how the COD V-22s alter the USN's conops once they get used to them.

Not to derail the "Oopps, I Bought Another Model" thread any further:

BLUF: I picked up the Testors 1/48 boxing of the Osprey - plenty of differences from the later Italeri kit  so I had the idea to mark is as a "civilian" aircraft that is actually owned/operated by the CIA for supporting "people that aren't there, doing things they shouldn't be doing."

Just remember, the Hellfire racks have to be positioned so that you don't kill your rotor, with the nacelles in the flight,  forward, position, when you fire.  That effectively means they'll need to be forward, close to the cockpit, as on the armed demonstration done with the ATTR.  You could put something that just drops, like drop tanks or torpedoes, aft of the rotor but not something that shoots forward.  Working with the aircraft for a few years now has given me a much better appreciation for it and the restrictions the concept imposes.  Also remember that any fuselage guns need to be aft or out the rear ramp to make sure you don't hit an engine nacelle.  If you have any questions on the V-22, feel free to message me.

I'll definitely ask for some help/ideas for these nacelles - I'm pretty sure they don't have the "elephant ear" scoops on them...

The rough idea now regarding weapons' emplacement is that the hellfires will be mounted in covered, recessed bays on the belly, so they extend down for launch but can only be used in "helicopter mode." Same for the miniguns - they'll be mounted to retract into the fuselage at the forward door, with an additional hatch put on the opposite side, and probably one on the tail ramp for good measure.

Maybe put this one "on a stick" and have it gear up, weapons out, coming into an LZ? Then I'd need some 1/48 pilots and gunners...
Yeah, the "elephant ear" scoops are very noticeable and quite missing on a lot of kits (in 1/72, I think only Hasegawa has them).  If you go with forward-firing Hellfires in under-fuselage bays, you could use them in forward flight, too.  I suspect side door/hatch miniguns could only be used in helicopter mode.  As an odd bit of armament, how about an MLRS "six-pack" or an equivalent sized box firing out the ramp?

I have 4 M134s coming from Live Resin, and they'll all go aboard this recently acquired V-22.  I also found some Air America markings, so that's the livery she'll be wearing, probably in an aluminum or silver with blue stripes/trim paint scheme.  I'm also thinking of taking a stab at making prop blur discs in place of the protors...if it's going to be on a stick, I may as well go all out, right?

I have that kit, too, and I figure to obtain or clone some ESSS pylons from some MH-60's to properly carry some accurate torpedoes (Brassin does some nice ones).  Really, that stores location works only for unpowered (in flight) dropped weapons or drop tanks.

For an armed MV-22B, I'm thinking of one with versions of the "moustache" weapons pylons trialed on N204TR mounted on both sides and carrying either APGW 2.75" rocket pods or 2 or 4 Hellfire racks per side; perfect for a forcible entry assault.

V-22 with ASW sensor suite could get there first and vector attack helicopters in on the target.  Alternatively, since torpedos are gravity-drop weapons, you might could fit a decent rack of them aft of the prop-rotor plane, somewhat like the SV-22A kit from AMT/Esci but with better racks to carry the torpedoes.

Actually, I'm doodling a SV-22 with a sonobuoy launcher rack replacing the standard aft ramp and supporting the winch for deploying a MAD "bomb" for tracking purposes.  That, coupled with torpedo racks, a carefully extended nose for better radar, and, possibly, a dipping sonar through the bottom "hell hole" would make for a formidable aircraft.  Then add the full E2E+ upgrade proposal for enhanced performance and reliability and you have something very distinctive.

Which works well for carrier operations, as you bring the transport helo's on deck & launch them, next come the attack helo's, then bring up the V-22's & launch them. Works much the same as a time-on-target artillery barrage.

Evan will know better (so feel free to correct me) but I would possibly consider using one of the rotary sonobuoy launchers as fitted to the new P-8 and have it fire through the same hatch as used by the BAE Systems Remote Guardian weapon:

The commandant decided it needed a turret. So "a wild turret appears" it's true that with the Nacelles the defensive fields of fire are more limited, but the people complaining about not having a "forward turret"... neither did the phrog, and the osprey needs far less protection in the first place as it is.

My understanding is that it did get trialed "in the sandbox" and was found to not be worth the cost in weight and volume.  I could see that after access being used for a sonobuoy launcher, though, as those are gravity-drop items that wouldn't interfere with anything.  My own thoughts are a dipping sonar there and sonobuoys on a replacement for the aft ramp, but that's my take on being able to use both.

If you look closely, you can see the fuselage underneath.  At first glance though it looks like just the wing and engines.

Evan: How difficult was it to get the pivot-wing mechanism to work?
My understanding is that the pivot-wing mechanism wasn't the biggest challenge.  The nacelle underwent several redesigns in the course from EMD to the current production configuration and getting the tilting aspects correct was a challenge (both the basic mechanism and the system interfaces between nacelle and wing).

I see the use of asuch MV-22-based ASW platform a good idea - especially its transitional speed!
Although, I think the MV-22 in its present form is too large, heavy, and complex!
I would have liked to have seen a XV-15 derivative in the ASW role!

By the time you grow the XV-15 to add personnel for the mission and mission equipment, you'd probably be getting close to V-22 size.  V-22 is no more mechanically complex than the XV-15 (I've seen details on both).  I'm thinking of an ASW CMV-22B derivative with a MAD bomb deployable from the rear ramp, or its replacement, sonobuoy chutes on an assembly that replaces the lower ramp, a dipping sonar option through the hell-hole hatch in the center of the cabin, and a couple lightweight air-launched torpedoes on streamlined external racks (similar to the ESSS pylons and racks on the UH-60) back near the main gear (you could carry torpedoes back there because they are gravity-drop weapons, not propelled forward weapons that would interfere with the prop-rotor arc.

If I can find some 1/72 ESSS pylons and racks, I've got most of the rest of what I need to do this in 1/72.

Thinking of self-propelled weapons that fire forewards, could the wing span be increased slightly, to put the propeller arcs further out?

Not easily, as longer wings would need to be fully tested and recertified.  Too, that would somewhat increase the logistics "tail" for the aircraft.  The addition of extra wing fuel tanks for the CMV-22B is an interesting enough effort.  I rather suspect that forward firing weapons will be on "moustache" pylons, much like what was trialed on N204TR, but on both sides.  Gravity drop weapons I could see aft of the prop-rotor arc but only those (save for any automatic weapons you may have firing off the ramp).

I can see another option - low hanging pylons on the fuselage sides.   To put the weapons firing trajectory just outside the rotor arc.

I can see there would be a need for recertification/etc. for longer wings but agree that would be a lot of effort - perhaps for a JV-22C?

The problem is its not foldy. MV-22s can get really small on deck, this was never built to be on a ship so you run into the same issue that Evan mentioned. By the time you make it shipboard ready, its going to get bigger so it can get smaller ironically.

Low hanging pylons run the risk of the stores impacting the ground as well as airflow problems over the airframe with those.

Took a long time to get the V-22 to work right but it seems to be working out well for the Marines. Marines should pick up the A-10s the USAF doesn't want anymore and use them for Osprey escorts.

Took a long time to get the V-22 to work right but it seems to be working out well for the Marines. Marines should pick up the A-10s the USAF doesn't want anymore and use them for Osprey escorts.

They are getting more work than they know what to do with:
 

"Next in line for readiness recovery is the V-22 Osprey – which reached initial operational capability only nine years ago but is “the most in-demand airplane in the world, and we’re loving it to death.”

Davis said this fleet has been operating at surge capacity since it was fielded and shows no sign of slowing down. Readiness has degraded because the tiltrotors are being used faster than ready forces can be generated. In theory, for every V-22 squadron deployed in a Marine Expeditionary Unit, one is just getting home and another is training to go out next. With three MEUs out at any given time, the Marines would need nine squadrons to sustain this 1:2 deployment-to-dwell ratio.

However, the V-22s are now also used in land-based Special Purpose Marine Air-Ground Task Forces (MAGTFs) in U.S. Central Command and U.S. Africa Command – meaning five squadrons are deployed and 15 would be needed to sustain.

“I’ve got 14. For a long time I had 13,” Davis said.
“So what that means is, we were moving maintainers from unit to unit to unit. Our [deployment] tempo is 1:2, or less than 1:2 in V-22. Going aboard the ship, going to Special Purpose MAGTF, basically we have no breathing space for our pilots or our maintainers in V-22. We have been at surge since 2007. … The airplane’s been incredible, just been incredible, but we’re basically outstripping our ability… to sustain it with spare parts and train the maintainers.”

The deployment tempo has not only taken its toll on the planes themselves, but also the personnel. There are no V-22 captains at the Expeditionary Warfare School and none serving as forward air controllers – both great career advancement opportunities – because they’re so busy operating at a surge rate.

The Defense Secretary recently approved a decision to cut the number of V-22s in the Special Purpose MAGTF- Africa from 12 to six, as well as cutting the number of C-130Js from four to two, giving the Marines a little more capacity for proper training at home.

“They’re still standing up squadrons and trying to make a move to Hawaii and everything else,” Davis said of the V-22 community.
“So we’re going to pull back a little bit from our overseas commitment in order to plus-up our training base and basically give us some breathing room.”

Any emerging requirements that can’t be met by the half-sized Osprey squadron in the Special Purpose MAGTF would be taken on by the nearest MEU, he said.

The service is still developing its V-22 readiness recovery plan now and will implement changes as needed, Davis said, but he’s optimistic that a slower operational tempo will help. Marine Helicopter Squadron (HMX) 1, the presidential helicopter squadron, is prioritized for obvious reasons. It has a stable base of maintainers with a stable workload, and it gets all the spare parts it needs in a timely fashion. As a result, HMX-1 had a 94 percent readiness rate over the last six months and only a 2.6 percent not mission capable- supply rate – a tenth of what the rest of the V-22 fleet saw – showing that the planes work just fine when properly cared for."

A-10s were offered and rejected by the marines in the early 90s same story with the army. Army citing costs, Marines that it can't be ship based.

Post by: Kerick on November 30, 2016, 01:56:17 AM
Good to hear the V-22 is in demand.
I was half joking about the A-10s but the Marines need an escort that flies faster than their Cobras and can stick around longer than a jet. That pretty much leaves A-10s or a gunship V-22. I hope the Air afore and the Marines are supporting each other in the 'Stan.

Just recalled, when reading some revitalised anti F-35 trash, that the MV-22 used to be in the same boat and that even now after being in service for years, exceeding user expectations and transforming what the USMC can do and how they do it, there are still people calling it a death trap and demanding the projects cancellation.

It strikes me that an unfortunate number of uninformed people are not only unaware that they are uninformed and way off mark but that they are actually exhibiting signs of being delusional.  Perhaps this explains what is wrong with the world today, too many delusional people?

Yeah, it would likely look cool, but as close to the ground as the exhausts of a standard MV-22 get, I suspect you'd really be boiling water with a seaplane, if not immersing the exhausts in water.

Deepen the hull (and reshape it), add floats with deflectors to the wings and it should float high enough not to submerge the exhausts.
Title: Re: Tilt-Rotor Aircraft
Post by: elmayerle on September 19, 2017, 11:19:37 AM
Yeah, that might be possible, though it would definite require some major wing redesign, too, to properly anchor those floats to structure (not impossible, but challenging).  The other approach would be to rewing the aircraft with new wings and engine installations more like the V280's where only the prop-rotors and immediate transmissions rotate; that would get your exhausts out of the water.  In that case, you might want to widen the main landing gear sponsons to provide better stability in the water.

Yeah, that might be possible, though it would definite require some major wing redesign, too, to properly anchor those floats to structure (not impossible, but challenging).  The other approach would be to rewing the aircraft with new wings and engine installations more like the V280's where only the prop-rotors and immediate transmissions rotate; that would get your exhausts out of the water.  In that case, you might want to widen the main landing gear sponsons to provide better stability in the water.

What about like this

A V-22 done that way might work.  You would need to be careful, though, to keep the floats out of the areas swept by the prop-rotors.

Or just tilt the rotors, rather than the engines and rotors.

I believe that's the V280, like the V280-style redesign I suggested on Monday for adding amphibious capability.

If they were located under the wings and didn't project fore and aft of the wing, it would work IMO.

Yeah, but you are going to need them projecting forward for balance when floating (a matter of stability when at rest); be far easier to set them far enough down to be fully out of the prop-rotors' arcs under the most severe external environments.

How about a kit bashing between the V-22 Osprey and the Grumman Albatross?

Albatross fuselage sans wing mated to the entire wing assembly of the V-22 Osprey to create a tilt-rotor amphibian.  The wing mounted floats from the Albatross will need to be located on the Osprey wing somewhere near the engines I suspect.  Reality check about suitability for actual flight to be ignored.

1:72nd scale Revell (former Monogram) SA-16 Albatross kit with the aforementioned parts from the HobbyCraft, Italeri, ESCI, or Hasegawa V-22 kits, depending on your ability to afford this project.

1:144th scale now has a V-22 kit but I am not aware of any Albatross in this scale.

1;48th scale Trumpeter Albatross and of course the Testors'/Italeri V-22 kit if you really want to spend some money.

Title: Re: Tilt-Rotor Aircraft
Post by: elmayerle on April 24, 2018, 12:08:34 PM
I would probably go with moving the floats to sponsons off the fuselage rather than leaving them on the wing.  Something you would need to be careful of is how far the aircraft sits in the water so that the exhausts don't get submerged while floating (as an alternative, modifiy the IRS so that the exhaust is redirected out the side with blocker panels and similar moving pieces, similar to the thrust reverser set-ups on several airliner nacelles - a few scribed lines could indicate this on the model).

Given that the V-22 wing and center section is manufactured as one large assembly, attaching it to the top of the Albatross would take some careful plastic surgery but is doable.

Folks, you don't have to choose between fully horizontal, or fully vertical
rotors.

(https://upload.wikimedia.org/wikipedia/commons/thumb/b/b2/V-22_Osprey_tiltrotor_aircraft.jpg/1200px-V-22_Osprey_tiltrotor_aircraft.jpg)

Rotors at an angle that allows forward firing of weapons wouldn't be hard to accomplish.
Title: Re: Tilt-Rotor Aircraft
Post by: Kerick on September 29, 2018, 01:11:13 AM
There would have to be some sort in of safety lock to prevent from firing until the rotors were at least the right angle. Not a problem in whiff world.
Title: Re: Tilt-Rotor Aircraft
Post by: elmayerle on September 29, 2018, 01:41:40 AM
It would definitely require a redesigned wing.  The present wing is a very large fuel tank and would need new structure and wiring provisions to add pylons like that, particularly when you consider that the present wing skins are fairly large bonded structural pieces.

The company claims its High-Speed Vertical Take-Off and Landing aircraft could blend “the hover capability of a helicopter with the speed, range and survivability features of a fighter aircraft”. Such as system would be capable of “low-downwash hover” and “jet-like cruise speeds over 400kt [740km/h]”, the manufacturer says.
