Su-47

Su-47 ""Berkut"" are similar to those of Su-37, although they are different aircraft, and the back portion, front portion and canopy are similar to those of the Su-35. The first two prototypes of this aircraft were evidently designated the S-32, and the S-37 designation was previously applied to an unrelated fighter project for a smaller delta wing single aircraft that was cancelled due to lack of funding. The Su-47 features forward-swept wings, which promises a range of benefits in aerodynamics at subsonic speeds and at high angles of attack. The forward-swept wing, which enables the aircraft to increases its range and its maneuverability at high altitude, it makes extensive use of composite materials. The aircraft has large canards mounted on the intake side, close to the leading edge of the wings. The vertical stabilizers are canted slightly outward not inward, as previously believed, and two large auxiliary intake doors are visible on the center fuselage section. It is not clear which engines are used on this aircraft. The two power plants are at the moment D-30F6 turbojets which are normally used at the MiG-31M, while the second prototype uses the Ljulka AL-37FU turbojet with thrust vectoring. An experimental the Su-47 is program for developing fifth-generation for our technologies today’s.
