  • Sukhoi SU 47 Burkut

    Hey i was looking at the Burkut and wanted to know if anyone knew the flight performance and service availability of it?

    That project was part of the PAK FA program for 5th generation fighter. That design has been scrapped.

      Do you know why?

        The plane was just an experimental one to evolve into the next 5th gen plane.
        It had the following characteristics.

        The Su-47 has extremely high agility at subsonic speeds, enabling the aircraft to alter its angle of attack and its flight path very quickly while retaining maneuverability in supersonic flight. The Su-47 has a maximum speed of Mach 2.34 at high altitudes and a greater than 9g capability.[2]

        Maximum turn rates, and the upper and lower limits on airspeed for weapon launch, are important criteria in terms of combat superiority. The Su-47 aircraft has very high levels of maneuverability with maintained stability and controllability at extreme angles of attack. Maximum turn rates are important in close combat and also at medium and long range, when the mission may involve engaging consecutive targets in different sectors of the airspace. A high turn rate of the Su-47 allows the pilot to turn the fighter aircraft quickly towards the next target to initiate the weapon launch.

        The swept-forward wing, compared to a swept-back wing of the same area, provides a number of advantages:

        * higher lift-to-drag ratio
        * higher capacity in dogfight maneuvers
        * higher range at subsonic speed
        * improved stall resistance and anti-spin characteristics
        * improved stability at high angles of attack
        * a lower minimum flight speed
        * a shorter take-off and landing distance

        Since then it has evolved into the T 50 project for 5th gen fighter with partnership with India. Ideas were also got from the Mig 1.44 experimental plane

          With such advantages gained from forward swept wing design, would a further aircraft of this type of configuration not be a likely option?
          Also if such clear advantages were the case then why would western designs not follow suite?

            The forward swept wings were a problem tough it had good maneuverability.
            The downside of such a wing design is that it produces strong rotational forces that try to twist the wings off, especially at high speeds.

              Minor correction. It's the S-47, not the SU-47.

                Its got twin designation of Su 47 and S 37

                  The airplane now called Su-35 seems to have no canards, true 3-D thrust vectoring and turbo-jet engines (rather than turbofans?), better for very high altitudes? Is then an interim aircraft before PAK-FA? (Personally my feeling is internal weapon bayed ‘stealth’ fighter aircraft make big tactical compromises).

                    The current designation of the PAK FA project is T 50

                      I wonder why its T-50. Tech 50. It could have been something better. Plus T-50 is a designation for another plane.
