Amazing Borovik!

Great work. Thanks.

lark · 4 September 2007

Just a question Borovik ,
Was there any relation between the Lagg-3 (VRDK) and the Gudkow Gu-VRD ?

Thanks in advance.

Antonio · 4 September 2007

Thanks Borovik,

Impressive post as usual :

Fascinating beast. Thanks

Antonio · 1 April 2008

Borovik, could you give somo details about that Er-2 version powerplant?

The designation is E-3130?

Thanks in advance,

Antonio

Hi,

here is the MiG I-250 Models; N-1,N-2 and MiG-13.

Stargazer · 31 October 2010

Amazing thread which I'd never seen before. Wow!

Does the "Su" in "Su VRDK" indicate a Sukhoi design?

narount · 31 October 2010

hello, sorry for my English but I am French (and this applies all the excuses ;D).
An excellent book (in French) by Herbert Leonard talks about the Soviet fighters and contains an entire chapter about the famous "half-jet" whit fantastic profiles.

Welcome narount! Yes, it is indeed a fantastic book! Don't have it myself but I purchased it as a gift to my dad years ago and it's a book he has cherished dearly over the years.

Wow amazing drawings!

Skyraider3D · 5 November 2010

Great stuff. Did any of these get built besides the I-250?

Of course the Su-5 (I-107, aka Aircraft "D") was built. It made its first flight on April 6, 1945. Two were built, but the second prototype didn't fly - it was only tested in TsAGI T-101 wing tunnel.

Pelzig · 5 April 2011

But bear in mind that Campini's patents for this type of aircraft had been around since 1931-1932. The Sukhoi VRDK bears some traits to Campini's unbuilt patent drafts, notably, a forward cockpit, annular inlet, and, of course, the motorjet. Seems unreasonable to believe that Russian designers were totally unaware of Campini's work for over a decade. Plus, Flight magazine was discussing Campini's designs starting in 1941.

Was the USSR that locked down that engineers and designers had no access to outside information such as magazines, patent data, etc? Or is it a matter of pride and denying influence from outside sources?

Hello Ed,
No further information on the impact of the Italian experience, I have not found and archivist of Sukhoi DB. V.Proklov’s (except as an obvious principle of similarity with CC-2).
Kept only the general form of the aircraft and layout scheme VRD, as it was in fact, we can only presuppose.
I personally, as well as the author of the article N. Valuev is inclined to the first question.
On denying influence from outside sources, I did not write.
Believe me I do not have and had no desire to participate in a "tug of war" to the same nothing new since 1910, after the precedent of the Great underrated Romanian Henri Coanda not (unfortunately most of the "Coanda effect," said outside the context of aviation, for example when a shed liquid from the kettle) ))
Matter of pride - applies only to the enthusiast, devotee of science, such as A.Lyul'ka, I.Merkulov, etc. Overall, the program development of jet aircraft in the Soviet Union (primarily turbojet engines, as undoubtedly the most promising) in the first half of the 40's had failed because of apparent underestimation by management of the aviation industry prospects for jet aircraft.
What kind of pride we talking about?
Well, if you still remember that Russia - the native land of elephants (a phrase from a joke)). Then the first who suggested the idea to use moto-compressor engine/ "motorjet" was a Russian engineer Gorokhov(1909). But this is only a theory, but in the history of the first practices are ...
H. Coanda - 16 december 1910 (short takeoff)
He-178 E.Heinkel 's - 27 August 1939 with piloted E. Warsitz
Caproni Campini N.1 by S. Campini - 27 (17?) August 1940 with piloted M. De Bernardi etc.
Sorry for the cost of auto-translation.
Regards, Anatoly.

The layout of TsAGI S-2 confirms my theory about Sukhoj "K". It was not a Me-262 copy.

Hi Alberto.
Just look at the comparison scheme technology partitioning of the two aircraft ...

... But the copy of the RD-10 (Soviet clone of the German Jumo 004) and their arrangement increases this impression.

So far not been published.
I can offer its own reconstruction made from the top view and side view (see Reply # 8 on: March 31, 2008)

Great work my dear Borovik.

Stargazer · 9 July 2013

I could be wrong, but I couldn't find a thing on this forum about the Sukhoi Su-7R mixed-propulsion prototype.

Here is a set of pictures from Polish magazine nTW dated October 1997:

Mustang1957 · 9 July 2014

The USN Had a Fighter Called The Ryan FR-1 Fireball. Had a Wright-Cyclone Radial Up Front And a Small Jet Engine In Back. Went In Service Late In The Pacific War,But Saw No Combat.

Mustang1957 · 9 July 2014

Here's A Drawing. B) Oops,My Bad :-[ The Fireball Was a Production Aircraft. Sorry Guys. Dale

hesham · 9 July 2014

Yes Mustange,

and its competition had some half-jet aircraft and projects;

MONTHLY MUNITIONS REPORT

The W-14 Plane Program

WAR PRODUCTION BOARD
Bureau of Program and Statistics
Military Division, Aircraft Branch
April 24, 1945

"The newest and most promising torpedo bomber, Grumman's TB3F, was first scheduled in a revision to W-13. Production of the TB3F is scheduled, to begin in March 1946 and to reach 50 a month in December. Like the FR Fireball fighter, the TB3F will have both a conventional and a jet engine — its R-2800C and West-inghouse jet engines will give it far more power than any other torpedo plane."

Anther great info Ryan,many thanks.
