Russians had to buy Chinese so they can make S-Ducts

>august 2011

not really. they're an engineering nightmare as they twist weirdly, needs composites not to tear apart, but once the layups are perfected, no significant difference to other wings for ground crews etc.

The Yak-43 didn't have a lift fan, turbonigger.

F35 has more in common with an f16 than a yak43

and? it had STVOL and was purchased by Locheed-Martin as the basis of F-35.

LOL'd. your butthurt is hilarious.

What are the advantages to the forward sweep?

USAF can turn Soviet scraps into a first rate aircraft, Russia can't even get a large enough production line for new fighter engines.

Ufimtsev didn't develop stealth. He solved several equations that predicted the way electromagnetic radiation would reflect off of surfaces. This is a huge leap from "he developed stealth", and it's rather telling that the Soviet Union never had concrete plans for a stealth aircraft, with Russia still struggling with the technology 30 years later.

You're trading top speed for maneuverability

Retard

lol'd. let's see some citations.
Anyway, Ben Rich says you're wrong. Stay mad nigger.

Yet the us were buying soyuz rocket engines up to 2018. Stop being a whiny nigger and do something with your life to prove yourself. You frame of thought is that of a basketball american. Good day.

>Retard
LOL'd. Your butthurt is fucking immense kiddo. Loved the counterargument.

It's fucking hilarious that the US still doesn't have the capability to put people in space.

mfw vodka americans can't stop throwing up long enough to equip a full airforce of 5th gens despite having the tech

No one's willing to fund it. We'd rather pay for social services for illegal immigrants.

>Anyway, Ben Rich says you're wrong.
Incorrect. He actually brings this up in Skunk Works- Ufimtsev's work languished in the back of a scientific Journal until a Skunk Works engineer translated it into English and realized what the discovery could be used for. From there it was a process of refining numerous test models and developing RAM coatings. All of this, while the USSR completely ignored the Professor's work.

That's like saying that a person who invents a formula for predicting the reflection and refraction of light deserves sole credit for inventing a camera. The guy figured the math, which was incredible, but clearly not many on that side of the curtain thought much about how to use it in such a way.

lmao it's almost as if VTOL has been experimented with since even WW2

We have a private company that can do it

>MUH RAM COATINGS
LOL'd even harder than before! RAM coatings add between 5-7% of LO effectiveness. Again, according to Ben Rich. Even if you don't have any, you're still fine.

>We have a private company that can do it
Which private company can send people to ISS? LOLing fucking hard at how butthurt you are!!!!

their waifus

greatly improved stall characteristics, lift.

In any case, you seem to have failed to comprehend my post. The fact that a Russian research paper helped Lockheed to develop a computer program to calculate RCS does not mean "THe Russians invented stealth". As it appears now that you're the Armatard, this conversation is over.

Look it up, you lazy nigger. I already told you who said it. I've already proven you wrong on every bullshit you brought up. Go fucking educate yourself on your own time and use a search engine.

From the other threads:
Aint going to waste my time to write an answer to this picture, straight from the archive:
A little list of stuff that is fishy on a short glimpse in this picture alone >Yak uses dedicated vertical thrust jets not a lift fan
Obvious difference hence why they lie about it.
>work of Petr Ufimstev was deem to be useless for soviets and so it was allowed to be puplish publicly
American making stuff work russians could not.
>the picture of the YAK-43 is according to wikipedia from a site for vector graphics that is offline, great source
On top of that every vantik like you would have shitted all over me for using something from wikipedia, while almost all the text on the picture is from there.
>there is no source at all for the YAK-43 using s-ducts
Inb4 "but YAK-40 and YAK-42 had them". Yeah they had them but they are fucking civilian airliners and entire different planes

Wrong

>A great deal of misinformation has appeared on the Internet regarding the relationship of the Soviet Yak-41 (later Yak-141), NATO reporting name Freestyle, to the X-35 and the rest of the JSF program. The Pratt & Whitney 3BSD nozzle design predates the Russian work. In fact the 3BSD was tested with a real engine almost twenty years before the first flight of the Yak.
>Throughout the 1970s and 1980s, the Soviet Navy wanted a supersonic STOVL fighter to operate from its ski jump equipped carriers. At what point the Yakovlev Design Bureau became aware of the multi-swivel nozzle design is not known, but the Soyuz engine company created its own variant of it. The Yak-41 version of the nozzle, from published pictures, appears to be a three-bearing swivel duct with a significant offset “kink.” The Yak-141 also used two RKBM RD-41 lift engines – an almost identical arrangement to the Convair Model 200 design. The aircraft was also re-labeled as a Yak-141 to imply a production version, but no order for follow-on series came from the Russian Navy.
>Yakovlev was looking for money to keep its VTOL program alive, not having received any orders for a production version of the Yak-141. Lockheed provided a small amount of funding in return for obtaining performance data and limited design data on the Yak-141. US government personnel were allowed to examine the aircraft. However, the 3BSN design was already in place on the X-35 before these visits.

>Kevin Renshaw served as the ASTOVL Chief Engineer for General Dynamics and was later the deputy to Lockheed ASTOVL Chief Engineer Rick Rezabek in 1994 when the 3BSD concept was incorporated into the X-35B design. Renshaw continues to work in the Advanced System Development branch of Skunk Works where he is currently working on flight demonstration of the DARPA ARES VTOL UAV program.

>DAT MASSIVE BUTTHURT of a guy who argues with Wikipedia, Ben Rich, Lockheed-Martin, Reuters, AP and other facts
you actually make me feel sad for you. schizophrenia is a helluva disease.

>that obvious butthurt for getting his shit kicked in
>using the word schizo
Oh, Ivan, please never change your autistic screeching and helplessness is just too darn amusing.

>throwing a tantrum about wikipedia, while defending a picture that is almost entirely based on it
Is that what schizophrenia feels like?
