Hi,

the Bratukhin B-12 was a project for single-rotor training
helicopter with anti-torque tail rotor in various versions
with M-14 or twin M-11 engines.

Also the designer worked on a project for piston-engined
[ later gas turbine ] convertiplane which formed the
conceptual basis of the Kamov Ka-22.

I spoke before about B-6,

and here is an info about B-6,B-7 and B-8;

To a high degree of perfection of the designers brought the bureau
projects a heavy landing vehicle B-7 and Agricultural B-8. The B-6 is a
longitudinal twin-screw helicopter project scheme.

Not out of the stage designs machine B-6 longitudinal scheme
and farm B-8. December 12, 1947 The Council of Ministers in
the decree "On the helicopter," demanded a stop to construction
of the giant B-7, and developmental testing F-4, B-5.

Was Bratukhin's group folded into the Kamov Design Bureau?

Was Bratukhin's group folded into the Kamov Design Bureau?

If I have correctly understood a question.
OKB-2 by Kamov from the end of 1948 to work in one area of the plant (GOSZ-3/ ГОСЗ-3), so to speak under one roof, together with OKB-3 Bratukhin's, independently of him.
Part of the design-office staff Bratukhin were transferred to the OKB -2 to gain a new design team.

Excellent as usual my dear Borovik.

Combat helicopter "Omega" armed with machine guns and cannonsp

 

[mil]

I think that this project is Bratukhin B-14

 

[borovik]

I think that this project is Bratukhin B-14

Four-sitter B-14 to be used as: a connected, training, air reconnaissance, artillery spotter, etc.
It was the last deep development Bratukhin in OKB № 3.
You specify a transport helicopter project is also featured in the book Mikheev, but without any numbering / unknown project rotorcraft I.P.Bratuhin /

Hi,


here is anther drawings for two Bratukhin Projects.

 

[hesham]

Title slightly changed, as most of the types aren't that "superheavy", I think.

That's right my dear Jemiba.
