Various Post-War Yakovlev (Yak) Projects & Prototypes

[Vasily41]

Beautiful work Zizi !

 

[hesham]

As I know there was two Yak-U variants,

the first had twin engined and the second gad single engine.

 

[Vasily41]

Really? This I did not know.
Are there any illustrations or descriptions regarding the design?

From Аэрокосмическое обозрение 2012-3,

very strange,you feel there was early drawing to Yak-60 and later one was different ?.

Unknown Yak-30 project with T-tail

A twin-engine Yak-30? I have never heard account of this.

Yak-25 “Burlaki” for the concept of a parasite fighter. Was planned to be hooked to a Tu-4, but problems like an unpressurized cockpit while the engine was off killed the idea.

Nice find Grey Havoc. Let’s hope that Yakovlev gets the necessary funding for their new VSTOL supersonic fighter that is currently being designed.

I can't ID this Yak Project exactly,maybe it looks like Yak-60 ?,could be
anther thing,MiG design for example ?,but why they insisted it was
developed from DFS-346 !.

Also possible it is just a hypothetical concept ?.

Hello!


I hope, that this small pictures from Polish magazine "Lotnictwo" 2015-06 could be a good teaser to Wiktor Druszlakov article about little-known Yakovlev fighter projects.
Types, mentioned: Yak-29, -30; Yak-40, -41; Yak-60; Yak-50.


The images was absolutely new to me!


All copyright belongs to author and magazine.

Yak-29 there seems very similar to one of the PVRD Ramjet Project Designs.

That same design is on the cover of Popular Science magazine from January 1951, I think it is in the discussion of Western artists concepts of Soviet Aircraft. IIRC it is marked Yak-25. I think it is an artist concept of what was ultimately the MiG-15.

Hi,

SimplePlanes | Yak-36 VTOL prototype 2

PC and mobile game about building airplanes.

www.simpleplanes.com

Be aware that the information on this page is slightly incorrect as the aircraft referred to in the text in French references the Yak-36 VTOL prototype, yet the illustrations are for the Yak-36-70 light strike concept based around the same engine configuration as the Yak-36. In the text, the engine is stated as "a vertically mounted fixed engine, rotary nozzles and a conventional fuselage", which is not strictly correct, as the Yak-36 had two horizontally mounted R21M-300 engines with vectoring thrust nozzles and no vertically mounted jet-lift engines. One of the prototypes survives at Monino and, in common with other aircraft there, it is depicted in a scheme that was not worn by the type at all during testing and resembles the in-service scheme applied to Yak-38s.

The Yak-36-70 was drawn up in a couple of different variants, the light strike variant and a light fighter variant, both of which resembled each other. I have seen a photo of the heavy cruiser Kiev with models of these on the flight deck, instead of the Yak-38s that it went on to receive. The Yak-38 differed in that the engine configuration was changed completely and a single engine was mounted horizontally in the fuselage fitted with vectoring thrust nozzles, and two vertically mounted jet-lift engines aft of the cockpit. Oddly, the pre-production prototypes of the Yak-38 were designated Yak-36M, even though their configuration was different to the Yak-36 testbed and the Yak-36-70 concept.

Excuse the photo, I took it during a rainsoaked visit to Monino years ago and I wrote on the back of the prints to identify them.

Hi,


in the article of Polish magazine,they mentions the Yak-41,and there is two Yak-40 &
two Yak-41 designs;

http://www.secretprojects.co.uk/forum/index.php/topic,4180.msg33059.html#msg33059

Major cool that the dimensions of the ramjet engine were finally given: L = 2.5 meters, D = .55 meters.
