My dear Jemiba,

there is a little different,please see the drawing from Luftwaffe Archive site;

Jemiba · 20 May 2014

That's much better, I think, just compare it to photos. The other looks to me, like
based on descriptions only (cockpit has more the shape of that, of the He 177 A-7,
tail turret, wheel spats with wrong shape ...), so errors would be understandable.

Is that EF-132 B2 a real project?

blackkite · 31 January 2016

Main landing gear is twisted then retracted to dodge the flap.
We can see something at both side of the fuselage near wing trailing edge. What is this? STARTRAKETEN(5000kp START ROCKET)?

Absolutely real. As far as I know the construction of two copies of the EF-132 is this version, powered by the AM-TRDK-01 by A.Mikulin was to be completed by September 1948.

By the beginning of 1948 was nearing completion manufacturing layout, detailed engineering went aircraft parts and industrial equipment. Some systems and components - chassis/landing gear, infantry turrets - were ordered by other plants. The aerodynamic laboratory plant completed purge model airplane. Overall, however, the pace of work lagged behind scheduled. It became clear that to begin testing the machine in time will fail.
At the same time the Council of Ministers №2055-805 canceled the development of the most promising German planes - long-range bomber EF-132.

There was also an intermediate version of the draft with forward-swept wings.
______________________________
The Design Bureau OKB-1 B.Baade for internal designation EF-132 used letters:
for a preliminary design with forward-swept wing - A (Span - 33,900; Lenght -35,080)
with the usual, backward wing sweep B or B-1 (D.Sobolev D.Hazanov and in the book "German mark in the history of domestic aviation" on page 252 for the result of this version (Span - 34,400; Lenght -39,400)
and B-2 (Span - 36,400; Lenght -39,850)

Vladimir · 1 February 2016

Thanks, borovik!

blackkite · 1 February 2016

Many thanks borovik-san as usual.

EF-132 B2 wing plan form is very unique.
EF-132 FSW three side view drawing is for the first time for me.Fuselage is large.

Also we can see an intermediate version of the draft with normal swept wings isn't it?
It's vertical tail stabilizer area is small compared with FSW version.
FSW has inverse influence for directional inherent stability.

blackkite · 2 February 2016

What is the relation between EF-132 and EF-132 B2? Also B1 existed?
I feel the relation between EF-132/EF-132B2 and two of V bomber.
EF-132 EF-132B2
Span 34.4m 36.4m
Length 39.4m 39.85m

on dead http://www.oocities.org/hjunkers/ju_home.htm
was reported the jumo 211 A/B

I' m confused because on others sources they speak about DB 600 engines !

Skyraider3D · 23 July 2016

Does anyone have a legible copy of the Ju 287 V3 skin plan (Haut-Plan) by any chance?

I am very interested in the dimensions between the fuselage frames. This drawing was reproduced in Horst Lommel's excellent Ju 287 book (page 98 of the Aviatic Verlag edition) but I can't read the numbers. I don't know if a larger copy may have been published in the Schiffer edition of this book?

hesham · 17 September 2016

Asymmetric Ju-287.

Just two variants shown in a single drawing. I'm sure there were no plans for an asymmetric arrangement as it just doesn't make any sense.

hesham · 13 January 2017

In Luftfahrt History 16,

why they wrote on the drawings Ju-288 and not Ju-287,a misprint or what ?.

richard · 13 January 2017

A misprint , indeed .

hesham · 13 January 2017
