Working with DC-10 derivatives. These ideas are not original, I know.

Maybe...or maybe still a CC-150 Polaris (just not an Airbus ;))

Think KC-10 in this scheme:

I cannot tell a lie, it was me that done it.  :)

Those two are the result of finding that one of my large stock of Airfix DC9-30s had no landing gear, no idea why. So I thought the long one up, the 'TW', so I could make one aircraft out of two but only use one set of landing gear. The backstory says that McD built it as the largest possible DC9 variant using the original high lift wings of the -30 when they realised that a much better wing was needed to fly the up-coming -80 series, later to become the MD-80 of course.

The DC9-60TW, its full title, used two sets of -30 wings but didn't need a tailplane of course, but it did need larger engines so they came from a Welsh Models MD-82 kit, of which I have four (!). McD only built the one -60TW and farmed it out amongst various airlines to trial the idea but only AirCal liked it enough to buy it (and because I LOVE the colour scheme and had four ATP AirCal decal sheets.  :))

Then I needed something to do with the bits left over, despite the lack of landing gear, and the BJ was the result. The wings are one set of the -30's tailplanes and the tails are the other set sawn down a bit. The engines have to be mounted to the fin as their mounting pylons are used as wing mounts. The nosegear came from the MD-82 kit and the main gear legs are lengths of piano wire bent to shape. The colour scheme is a fictional one from my ex-employers who are based in Eden Prairie, MN, as I had the logos and corporate colour (Pantone 200 BTW....) already on my laptop.

Both of them will be entered in the appropriate Class at this year's SMW at Telford next weekend where hopefully they'll shock a few JMNs.  ;)

Excuse my ignorance.

The -70 Series were exactly that, weren't they?

Delta had a number of them and I built one from an old Revell -61 with the CFM conversion kit from ATP. I still have it somewhere but it's in a box of 'Lost Airliners' that I've been searching for for about a year now.  :(

Well, the short fuselage would still give you adequate room for sensors, consoles, and weapons bays and the extra power, and fuel economy, of the CFM56 engines would allow quite hot and high performance since they did excellent in improving the performance of the -60 series to the -70 series.  You could use the longer fuselage but it would be something of an overkill.  The short fuselage with CFM-56's could likely use any field a P-3 could, which helps spread them around.

There were some DC8-72s, CFM engine -62s, which were pretty short, 157 ft long as opposed to the 150 ft long Series -10 - 5-s. But way shorter than the monster -61s and -62s at 187 ft or so.

For a bit of extreme thread revival, how about a KC-10B made by adapting the KC-10A mods to an MD-11 airframe?  Skin the winglets with composites and put ESM antennas there for threat detection.

He! He!  any more details about that proposals Carl ?

I'm currently resurrecting my BAe 844 project, while I'm on poggy, my plan is to do some courses for the Inventor program I had bought a few years ago but never got around to using because my business was mothballed. My plan is to draw the conversion in 3D and then see if I can get it 3D printed.

Below is the BAe 844 I'm planning on building.

Re: MDD DC-9 'Air Stair' (Rear Passenger Ramp) Location
« Reply #25 on: October 23, 2020, 08:04:45 AM »
Can anyone share a drawing or URL that shows where the rear passenger door/ramp is located on the MDD DC-9?  My recent acquisition of the Aurora 1:72nd scale DC-9 kit has minimal details and most every image or drawing I have found so far on-line pretty much ignore this unique feature of the DC-9.   

I would like to try and scribe in the detail of the ramp on the underside of the fuselage if possible.

Thanks for the assist Guy!  The first image you linked to appears to have created a hot-link conflict and will not show. 
The other images are in view. 
The "Air Stair" feature for the forward access door is not featured on the old Aurora kit, just the outline of the door and according to my research efforts it was not fitted to all DC-9 aircraft.  The rear steps are what I am after.  The rear view does help some in establishing the width of the thing and I can do some more guesstimation on where it lies on the underside of the fuselage. 

Without getting in to too much detail.  The objective is to try and scribe in the rear access stairs or if possible create an open step feature for an "alphabet agency" clandestine cargo aircraft that could drop "stuff" at night or in adverse weather.  Based on something I read several years ago that I think was a B727 that had the rear stairs modified to create a ramp to allow delivery of small "door bundles" with parachutes in support of some guerilla war.  So with that in mind, I hope to create something similar from the DC-9.  It has no windows along the fuselage sides so it is almost ideal for a cargo carrier.

Seeing that rear stair reminded me of something, when I went to the Yeovilton Royal Navy Museum, they had one of the prototype Concordes on display and you could do a walk through the cabin. We accessed it through a rear stair ---- but exited through a side cabin door near the front.

Evidently most DC-9-10 don't have the ventral stairs and the old Aurora kit is more
or less a DC-9-10. Stairs were optional on later series. Non-stair aircraft have a
detachable tailcone and an escape chute. The built in fwd. airstair was fitted to all
but the freighters.

Page 33 of this airport planning doc shows the critical clearances for the ventral stairs.
The door measurements are 27.75" X 72". Page 28 shows the Fwd. Cargo Door on the
freighter versions, pg. 19 has the interior arrangement for a 'shorty' freighter, the Aurora
kit is a shorty DC-9.

@JCF - Thanks for the additional information.  I must have missed the bit on the ventral stairs not being on all versions.  The kit states it is a model of a DC-9-10 and that was about it.  I still like my idea of a clandestine cargo delivery aircraft with a ventral stair converted to a ramp with rollers to facilitate smooth delivery of cargo bundles in the dark of night.  :smiley:

Otherwise, it goes to the scrap heap...
