Junkers Ju 287 variants
I am interested in finding information on this aircraft, notably the variants. Does anyone have anymore variants of the Ju 287? Thanx in advance!

Re: Junkers Ju 287 variants
There is an article about Ju-287 on the excellent site http://perso.wanadoo.fr/prototypes.com/index.html
http://prototypes.free.fr/ju287/ju287-1.htm
For those who do not speak French here's a summary:
Ju-287 V1 with 4 Jumo 004B (testbed with He-177 fuselage, flown in 1944)
Ju-287 V1 (identical with Ju-287 V1, but not completed)
Ju-287 V3 with 6 RD-10 (Jumo 004B) and Ju-288 fuselage (flown in 1947)
Ju-287 V4 (identical with Ju-287 V1, used for static tests)
The drawing below represents the EF-131, a slightly modified Ju-287 V3
Ju-287 production model with 4 He S 011 (not completed)
EF-125 - projected development of Ju-287 production model with 2 Jumo 012 or 2 BMW 018 (not completed)
EF-140 - russian built EF-131 with 2 RR Nene (flown in 1948)

Probably for the same reason the US didn't. The forward swept wing, although it offers significant aerodynamic advantages (tip vortex is reduced if not eliminated outright), requires a very rigid and strong structure to avoid progressive twisting at high angles of attack and load. Until carbon fiber came along about 30 years ago, that was impossible without making it also prohibitively heavy.Topspeed wrote:I wonder this too ?! Why not ?Kurt_Steiner wrote:Wonderful pics!
Why did the Russians not go ahead with their development of the Ju 287?
And BTW, like the US X-29, the Russians have developed a forward swept aircraft. http://en.wikipedia.org/wiki/Sukhoi_Su-47

quiet a nice aircraft
Re: Junkers Ju 287 variants
What is that weird rear gun position on the second drawing?
Is that artistic licence or a real design?

Re:
They did go ahead because they recognized the benefits of swept wing tech. The EF 131 was completed after WW2 and flow in the USSR beginning in May 1947. There is a grainy photo of the EF 131 in Griehl (2004, p. 306).Kurt_Steiner wrote: ↑30 Oct 2004, 10:33Wonderful pics!

Re: Junkers Ju 287 variants
Hi,
There's photos of the nearly-completed second Ju 287 prototype in Griehl (2004, pp. 294-295), and the Ju 287 V2 was similar to the first prototype except that it had six turbojet engines and the tailplane was moved a few inches below the base of the vertical stabilizer. One of those photos shows the Ju 287 V2 after it was blown up by the Germans to avoid capture by Allied forces.

Re: Junkers Ju 287 variants
It's real. Two tail turrets were studied for the aircraft, FHL 131/Z with two MG 131 one above the other and an unspecified turret with two equally unspecified guns mounted side by side. Model photo is shown in Griehl's book, p. 304.
