Description

The Su-47 Berkut, whose initial prototypes were designated S-32 and S-37 Golden Eagle, is an experimental aircraft derived from the Su-27 Flanker class. After a test campaign in 2001, Sukhoi was selected by the Russian government in May 2002 to be the manufacturer of the next-generation Russian fighter aircraft PAK FA, which will be a development of the Su-47.

The design of the Berkut is based on a reverse-swept wing (similar to that of the X-29) and the use of the natural instability of the airframe to increase its agility. It indeed has considerable maneuverability, even at supersonic speeds, thanks to the use of a reverse-swept wing that offers numerous advantages. The Su-47 is also equipped with small movable canard surfaces. The fuselage is composed of aluminum and titanium, as well as 13% of the weight in composite materials. The wings are made up of 90% composite materials. The Su-47 also appears to have fairly good stealth capabilities, although they are inferior to those of the F-22 Raptor. The cockpit has been designed to ensure maximum comfort for the pilot, even under high G-forces. It is equipped with a next-generation inclined ejection seat at 60°. The avionics and armament system of the Su-47 will be particularly advanced, notably the NIIP N011M radar.
