SU-47 BERKUT - The best fighter in maneuvers - one with inverted wings - The Lamborghini of fighters
Berkut means golden eagle, in Russian. The first flight of Berkut was in September 1997, with the designation S-37 still. The first stage of flight testing was completed in 2001. Some of the features used in SU-27 (flanker, NATO) were also used in Berkut, as the canopy (cockpit), landing gear and derives double next vertical.
This game has FSW wings (Forward-Swept-Wing or wing with negative enflechamento), easily recognized by this feature. FSW wings means that are "swept-back" in the opposite direction to the usual one, namely, forward. This concept of wing is already studied for many years by the designers of fighters, but only in recent years with the use of computers in the dynamic correction of the flight, that can be used to really practical way. Wings in this regard provide great maneuverability even at low speeds, close to the "stall" (stall). However, without an assisted correction, it becomes dangerously unstable under certain conditions. The use of composite materials to reduce the wake turbulence generated by the wing was also a breakthrough that enabled the construction of the SU-47.
When comparing a pair of inverted wings like the SU-47 against a pair of ordinary wings of the same area, there are some advantages: Greater support, most sub-sonic range, increased maneuverability, greater resistance to "spinning "slower for the" stall "increased stability at higher angles of attack and lower track space required for both take-off and for landing. Wings in this direction give the Berkut extreme maneuverability at subsonic speeds and can quickly change the angle of attack and the line of his flight. This capability is essential for air superiority, it opens up more possibilities in the launching of missiles / bombs and cannon firing.
The Berkut pilot can quickly change your target, engaging in another as soon as he made the shot against the first. The possibility of fast corner is also an important factor for the acquisition of new targets.
The panels Berkut wings are constituted by 90% of composite materials. The fuselage structure is predominantly composed of aluminum and titanium plus 13% composite materials.
