Here I want to include a series of straight wing conventionaly configured early jets and some prop powered designs that I consider related and in some way beautiful and tasty

Interesting collection, one thing though, those are all 1940s designs.
:)
The Air Force Museum site has some good photos on the various type pages:

I have long liked the Convair XB-46 - the slender wings and long fuselage just look so appealing.

XB-46 has impressive performance for being powered by J35 engines.
Moving up to J65 and later to dry F404 (in Skyhawk fashion) would be interesting moves. Even considering critical Mach issues.
-
I wonder how well an XB-46 with piston/turboprops (for better range) would fair as a maritime patrol bomber? Its not much larger than a P2V Neptune, can carry more ordnance, but is shorter legged. Hmmm.... :)
-
I wonder what an XB-46 would look like in the role the WB-57(x) plays.
-

You are right. My fault :-[
-
And what about XB-48 with those 3 jet packs? that make me think in 4, 5, or 6 engines packs 8) :P

Cool notion, although you'd want to use a different design for the pack as the one Martin
engineers used created massive drag.
Looked good on paper, seemed OK in the windtunnel, full size not so good.
-
IIRC the XB-48's engines were actually in separate 'boxes' with small gaps in between, just because of the high drag problems JCF mentions. One weird design.
-
Yep, and the ducts between the engine were the problem, the air dammed-up between
the engine boxes and created the drag. A redesign that eliminated the 'floor' of the ducts
possibly may have fixed most of the problem.

Yeah, that can be a real problem. Look at the thickened nacelle pylon on the Lear 25G where the tight areas between narrow pylon, fuselage, and nacelle were eliminated with a definite reduction in drag.
-
A similar situation obtains with VC10s.
The pylon is a REALLY complicated shape and I don't think any model manufacturer has ever got it tight yet. It's twisted, cambered and tilted in every direction you could imagine in the quest to get the air going in the direction they wanted without causing lots of drag.
-
The XB-48 always looked to me to have been a Soviet or Eastern bloc design.

Yep, I can picture it painted up with red stars starring as a Commie bomber in a 1950s
Red-Scare flick.

Big bomber borrowing on IL-28 experience.

Cool (X)B-42 Artwork:

-
what are the cannon supposed to be, 40mm's ???
-
No idea - I think it is just artistic licence.
-
Twin 37mm, the other proposed armament fits for a solid-nose attack
variant were sixteen .50 MG or one 75mm and two .50 MG.
-
Cool artwork 8)
See a lot of Heinkle 100 in those Tony fighters.
-
Thanks Jon.
Here's another:

I always found the Custer Channel Wing to be a fascinating concept and I understand its STOL performance was very good.

I imagine it would have done well in SAR or air ambulance roles.
I wonder how it would have fared with turboprops.
From all I've read, the aircraft's single biggest problem was the guy running the show. Willard Custer sounds like he was a real piece of work.
-
Well, you'd need cross-shafting between the engines for safety (don't want way more lift on one side than the other) and I'd love to see what other special requirements the FAA would levy for certification. I will agree that Willard Custer doesn't come off sounding that good.

Updated XB-43

Enlarged version of Martin 4.0.4, equipped with the wings of XB-48 and their odd triple jet pods :mellow:
To avoid central undercarriage, not adequate for a liner, main u/c has been moved to sponsons in outer face of engine pods.

Interesting concepts and graphics. Disappointing that have not seen 1/72 Martin 404 kit. Did tour a parked 404.

I like the engine pod landing gear.

According to PAK-20 book, Combat Models does/did one and another company called Victor 66 did one too. As Combat Models is now closed down too, both would be a rare find.

That 1/72 Victor Sixty-Six vacuform did pop up on Old Model Kits but displays as now sold. Still, goes to show that there are 1/72 Martin 404s out there :smiley:

Airliner derived from Convair XB-46. Along with orignal XB-46

Er, shouldn't that be "...derived from Convair XB-46."? The proposed airliner derivatives from the B-36 were rather larger.
-
Post info about them, please. :smiley:

Regional liner based in North American B-45 Tornado.

-
Oh, I do like that
-
Post info about them, please. :smiley:
I would say they were based on the XC-99 wouldn't you ?
-
My fault, SORRY. I mentioned XB-36 by error, I meant XB-46. Already fixed.
IMO, XC-99 is based in B-36. XB-46 is not so big.
-
You could look at maybe an XC-99 based airliner with YB-60 wings and tail surfaces

Sure could :smiley:

XB-51 is a pretty strange project on its own. So I had to address several issues:
1. I removed the center landing gear and replaced it with a classic one.
2. I replaced the variable incidence wings with some classic ones taken from the F-86 (upscaled).
3. I solved the problem of lack of power by adding a fourth reactor, removing the central engine.
Here we can see 2 versions:
1. Closer to the original XB-51, in TWA colors, preferred by Howard Hughes.
2. More civilized, in Pan Am colors, chosen by Juan Trippe.

Very cool! 8) Especially the TWA version's layout.
