MW: The Russians took possession of the 5th generation fighter 20 years ago


In December 2020, the Russian Aerospace Forces accepted the Su-57 into operation, after which Russia officially became the third country in the world to be armed with fifth-generation fighters of its own production. However, few people know that the Russians took possession of the last generation aircraft more than 5 years ago, writes the Military Watch online edition.


In 2005, the F-22 Raptor was adopted in the United States, and in 2017 in China, the Chengdu J-20. Dozens of these fighters are used in their countries. At the same time, the Su-57 is probably necessary for the Russians to develop a breakthrough 6th generation fighter, which will enter the troops in large numbers.

One of the notable programs for the development of a fifth generation fighter in the Russian Federation is the Su-47 "Berkut". The aircraft is made according to the aerodynamic design "longitudinal integral triplane" with a forward swept wing. He first took to the skies in September 1997, 13 years before the flight of the Su-57. It was the Su-47 that made an invaluable contribution to the appearance of the Su-35 and Su-57, becoming an experimental board. It was produced in just one copy.

The wings made the Su-47 extremely maneuverable with unrivaled turning speed, and its combination with a thrust vectoring system made it the world's leading fighter. The wing design gave the fighter a higher lift-to-drag ratio, superior stability at high angles of attack, lower minimum airspeed, improved stall resistance and anti-roll characteristics. The fighter received a significantly longer range at subsonic speeds and could use much shorter runways due to the greater lift generated.

At the same time, the wing design, formidable for combat, also had a downside - it limited the speed to Mach 1,6, like the lighter F-35, another fifth-generation fighter of the United States. Moreover, the Su-47 wing was 90% made of composite materials, since the metal could not withstand overloads.

The Su-47 used the D-30F6 bypass turbojet engine with a common afterburner and an adjustable supersonic nozzle, as on the MiG-31 interceptors. The fighter could use a wide range of weapons.

      What do you call a third-rate Yusovsky site?

    Russian got hold of fighter of the 5th

    I, having read the heading with the word "captured", decided that somewhere the F-22 "hung". But it turned out that this is another example of the “lack of” knowledge of the Russian language when using computer translation. request

    If the entire "fifth generation" of the Su-47 consisted of a forward swept wing, the Americans received their prototype of the "5th generation fighter" back in the mid-80s, the Northrop Grumman X-29.

    In practice, it turned out that the reverse sweep, which undoubtedly had a positive effect on super-maneuverability, made the aircraft more unstable and difficult to control. This in itself is not a problem for modern automation, but the failure of this automation did not give the aircraft any chance.

      I worked in the Sukhoi Design Bureau in the early 90s. It stood (Su-47) in our experimental shop.
      The wing twisted during flight, which is bad, that's why they used a composite. But even then it was clear that this was a dead end.
      By that time, the Yankees had tests of both reverse streamer and X-shaped and asymmetrical wings on the flyers.
      Military Watch - to quote this does not respect yourself, a third-rate site of Mr. Pushkov, passed off as an American one.

    How is it really with these SU-57s?
    Here they write that the only one, torn off by the Army, stands in the hangar and does not fly. He was seen several times on the runway, but never took off. I ask what is truth. Your planes have always been of high quality, and we still use the MiG-29.

      They say that from this year they will collect faster. Judging by what appears on the network - debugging and optimization of production is in progress.
      Actually, here he (the first transmitted) flies
