The Su-47 fighter aircraft, previously called the S-37 Berkut or Golden Eagle, was developed by the Sukhoi Design Bureau of Moscow, Russia, and performed its first flight in September 1997. Su-47 is in a forward-swept wing configuration and uses a highly unstable triplane (with three main lifting surfaces) aerodynamic configuration. It retained some of the systems and component designs from the Su-27 (the all-weather supersonic fighter aircraft with Nato reporting name Flanker), for example, the design of the canopy, landing gear, some of the avionics, and the near-vertical tails. Su-47 manoeuvrability 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, and it also retains manoeuvrability in supersonic flight. The Su-47 aircraft has very high levels of manoeuvrability with maintained stability and controllability at all angles of attack. Maximum turn rates and the upper and lower limits on airspeed for weapon launch are important criteria in terms of combat superiority 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 enables the pilot to turn the fighter aircraft quickly towards the next target to initiate the weapon launch. Compared to a swept-back wing of the same area, the swept-forward wing provides a number of advantages: higher lift to drag ratio; higher capacity in dogfight manoeuvres; higher range at subsonic speed; improved stall resistance and anti-spin characteristics; improved stability at high angles of attack; a lower minimum flight speed; and a shorter take-off and landing distance. Su-47 fuselage The Su-47 fuselage is oval in cross-section and the airframe is constructed mainly of aluminium and titanium alloys and 13% by weight of composite materials. The nose radome is slightly flattened at the fore section and has a horizontal edge to optimise the aircraft’s anti-spin characteristics. Forward-swept wings The forward-swept mid-wing gives the unusual and characteristic appearance of the Su-47. A substantial part of the lift generated by the forward-swept wing occurs at the inner portion of the wingspan. The lift is not restricted by wingtip stall. The ailerons – the wing’s control surfaces – remain effective at the highest angles of attack, and controllability of the aircraft is retained even in the event of airflow separating from the remainder of the wings’ surface. The wing panels of the Su-47 are constructed of nearly 90% composites. The forward-swept mid-wing has a high aspect ratio, which contributes to long-range performance. The leading-edge root extensions blend smoothly to the wing panels, which are fitted with deflectable slats on the leading edge, as well as flaps and ailerons on the trailing edge. The all-moving and small-area trapezoidal canards are connected to the leading-edge root extensions.
