Yakovlev

Fri Jul 06, 2001 5:27 pm

So, lets start the first Yakovlev-topic in this forum:
I've got two questions in connection with that Russian design bureau:

1- There was once (or is?) the Yak-141 Freestyle, a STOVL or VTOL aircraft. Does anyone know something about that aircraft? Was it in service in the Russian AF? And how many were built?

2- Some days ago, in another topic in this forum, there was said something about a new Yakovlev prototype. Has anybody got info about that plane?


SU508, this is the chance for you! You can post something not totaly useless! You can post something else than "Sukhoi is great" and so...  Big thumbs up

Yak-141 is the world's only VTOL aircraft that can go supersonic. Avionics and missiles on Yak-141 are common to these on both Su-27 and Mig-29. According to "Modern Interseptors" book (Russian) this aircraft is 15-20 years ahead of anything similar in the West. I am not sure how many were made but one went to Franbough Air show in 1992. The project was canceled 1991 however.

How 'bout the JSF contenders, can't they go supersonic?
BTW, the Russians said that either Boeing or Lockheed-Martin "bought" the technology used in the YAK-141 to use in their JSF contender, don't know if it's true, though.

I would like some info on the new a/c too.
I assume the mentioned a/c is the new Russian 5th generation fighter that was supposed to be developed by Sukhoi and other Russian design companies, and was supposed to be the "Russian answer" for the JSF. See http://www.airliners.net/discussions/military/read.main/875/6/
Anyways, if anyone has any up-to-date info on the project, can you please post it?

15-20 years ahead of anything similar???
My opinion 'bout that: that's rubbish. What should be the big advantage of this VTOL plane? The V-22 Osprey is ahead of its time, but this aircraft doesn't seem so special...but, actually, I don't know enough about it, so I shut up...

Martin.

Again this web site shows that many people just don't want to understand the overall difficulty of designing an airplane. Yak-141 has 3 engines!

1 R-79 - 152/88.3 kN afterburning/nonafterburning
2 RD-41 each 41.8 kN for lift

The last two engines are actually almost vertical and have vector thrust.

All three engines must work in combination in order for Yak-141 to fly. The whole control system as I understand is digital "fly-by-wire". I am 100% sure that West had nothing like this in 1991. Hence this aircraft is ahead of time.

Hey, I didn't know so much about the Yak-141, that's why I asked for some info. And now I got it, thanks!

accordingto my oppinion freestyler is good naval fighter and there is some interesting decision about building the modern naval's but it is nothing compared with naval flanker and if you really know just a little about yak a suggest you to read do a little search on
http://www.google.com/search?q=yak+freestyle
http://www.fas.org/search.html
P.S. Su508 sometimes is really overdoing but i agree with him about somethning flanker are the very very very very very best

because of your P.S.: this criticism on SU508 isn't always really serious, but as you say he's overdoing.

The Yak-141 never entered service. All prototypes crashed...
Vertical takeoff would melt or burn almost anything, special metal allay plates were needed to deflect the exhaust sideways. Hardly practical in an operational environment.
I wish I were flying
