Alekseyev Fighter and Ground Attack projects

Great drawings, Borovik.
This book is only with italian language?


The I-21 and I-210 are different projects, right?
I-21 projected with TR-2 engines, I-210 with RD-20. (Than I-211 built with TR-1.)


(from book - Alberto Trevisan "Storia ed Evoluzione dei Caccia Sovietici a Reazione,1945-1955"

One and the same project. (If under the designation of I-21, we do not mean those planes ... http://www.secretprojects.co.uk/forum/index.php/topic,8112.msg76183.html#msg76183 ))
project, I-210 (I-21 Model 0) had to have two engines RD-20 (BMW 003), their thrust was not enough, as a substitute for considered the RD-10 (JUMO-004), but in the end it was It decided to build a fighter with two engines A. Lyul'ka TR-2 thrust of 1350 kgs.
Meanwhile, the development of motor TR-2 was delayed and eventually Alexeyev decided to adapt nacelle under the TR-1, whose static tests began in July 1946 under the designation I-211 (I-21 Model 1)
/Google translation/((
 
I-21 and I-210 was projects (to be powered with Lyul'ka TR-2 or BMW-003). Only the I-211 was built (2 prototypes).
The book is only in italian language, I guess.
 
Thanks Guys,

I made a comparative drawing where you can see the differences between the two projects.

Dear Borovik,
Can you send the table of contents of the book?

Oh, thank you very much!
I think, i want this book!


Are there accurate drawings from La-152-154-156?
 
Every plane included in the summary has at least an accurate profile drawing. The 3-views are very rough.
 
Hi, my five cents

Has someone photos or accurate drawing about I-215 D (bicycle gear version)?
 
Hi! Sh-218. Perhaps radiators are located inner side of the twin boom.

"The engine, mounted on the wing, was a Dobrynin VM-251 (in effect, half a VD-4, with three banks each of four cylinders) rated at 2,000hp. It drove an AV-28 contra-rotating propeller arranged for pusher propulsion, comprising two three-blade units each of 3.6m (11ft l0in) diameter."

VD-4 engine.

Hi! I-218.

The "218" was attack aircraft, not a fighter anyway. So it wasn't "I" and couldn't be "I". You can call it Sh-218, while simply Aircraft "218" would be more historically correct.

I can see aircraft 218-Ⅲ radiator at the wing root leading edge. Also I can see ram air intake and exhaust nozzle at the side of the fuselage.

Hi I-211,I-215 and I-216.
http://survincity.com/2012/05/transformer-alexeev-i-211-215-216-okb-21-fighter/

I-212.
http://www.airwar.ru/enc/fighter/i212.html
https://en.wikipedia.org/wiki/Alekseyev_I-212
"The Alekseyev I-212 was a twin-engined, jet fighter designed in the USSR in 1947 at OKB-21 (OKB - experimental design bureau). It was a two-seat variant of the I-21 (Istrebitel' - Fighter) designed in response to a requirement for a very long-range fighter issued by the Voenno-Vozdushnye Sily (VVS), (Soviet Air Forces), in 1946. Intended as an escort fighter, it was also designed for use as a night fighter and reconnaissance aircraft. No prototype was built, although some parts may have begun building before the project was completed."

"Variants
I-212: Initial version, never built.
I-213: Proposed heavier version with more fuel and only two forward-facing NS-23s and a single NS-23 in the tail barbette.
I-214: Proposed version with the tail barbette replaced with a rearwards-facing radar and heavier forward-facing armament.
UTI-212: Proposed training variant of the I-212 with both crewmen facing forward."

Don't you think it is strikingly similar to the French SNCAC NC.1071?
