Army and Weapons | Deadly Sukhoi Su-47 Berkut | The Sukhoi Su-47 Berkut (Russian: Су-47 Беркут - Golden Eagle) (NATO reporting name Firkin), also known as S-32 and S-37 (not to be confused with the twin-engined delta-canard design offered by Sukhoi in the early 1990s under the name Su-37) during the first development, was an experimental supersonic jet fighter developed by Sukhoi Aviation Corporation. A distinctive feature of the aircraft, the forward-swept wing that the device gave an excellent agility and maneuverability. While the series production of the type never came, the sole aircraft produced served as a technology demonstrator prototype for a number of advanced techhnologies later used in the 4.5 generation fighter SU-35BM fighter and the current 5th generation Sukhoi PAK FA prototype.
The Sukhoi Design Bureau of Moscow, Russia has developed the Su-47 (previously called the S-37 Berkut or Golden Eagle) fighter aircraft, which first flew in September 1997. Su-47 is a forward-swept wing configuration and uses a highly unstable triplane (with three main lifting surfaces) aerodynamic configuration. The Su-47 was introduced in January 2000 and completed the first phase of flight tests in December 2001. The aircraft is managed by the Russian Air Force
In May 2002 Sukhoi was selected as prime contractor for the next generation of Russian PAK FA fighter program. The PAK FA fighter aircraft is a development of the Su-47, but without the forward swept wings. The first test flight of the PAK FA fighter aircraft was completed on January 29, 2010.

The design of the high maneuverability prototype is based on the avionics and aerodynamics technologies developed for the Su-27 upgrade program.
Part of the systems and components designs from the Su-27, (the all-weather supersonic fighter aircraft with NATO reporting name Flanker), have been used in the Su-47, for example the design of the canopy, landing gear, part of the avionics and the almost vertical tails.
The Su-47 has extremely high agility at subsonic speed of the aircraft to the angle of attack and flight path change very quickly, and it remains maneuverability in supersonic flight.

Maximum turn rates and the upper and lower air speed for weapon launch are important criteria in terms of fighting superiority. The Su-47 aircraft has a very high degree of maneuverability while maintaining stability and controllability at all angles of attack.
Maximum turn rates are important in close combat and also medium and long distance, when the mission may involve working on consecutive targets in different sectors of airspace. A high rotational speed of the Su-47 fighter aircraft, the pilot quickly toward the next goal to begin launching the weapon.

The swept-forward wing, compared to a swept-back wing of the same area, a number of advantages: higher lift to drag ratio, a higher capacity in dogfight maneuvers, higher range at subsonic speed, improved stall resistance and anti- spin features, improved stability at high angles of attack, a lower minimum flight speed, and a shorter takeoff and landing distance.
Trunk
The Su-47 fuselage is oval in cross section and the hull is mainly constructed of aluminum and titanium alloys and 13% by weight of composite materials. The nose dome is slightly flattened at the bow and has a horizontal edge to the plane of the anti-spin characteristics to optimize.

Wings
The forward swept midwing gives the unusual and distinctive appearance of the Su-47. A substantial portion of the lift set by the forward-swept wing occurs at the inner part of the span. The lift is not restricted by wingtip stall. The ailerons - the wing-control surfaces - remain effective at the highest angles of attack, and controllability of the aircraft is retained even in the case of the airflow to separate from the rest of the wings' surface.
The wing panels of the Su-47 is made of almost 90% composites. The forward-swept midwing has a high aspect ratio, which contributes to long-range performance. The leading root extensions to run on the wing panels, fitted with deflectable slats on the front, flaps and ailerons on the trailing edge. The all-moving and small-area trapezoidal canards are connected to the leading-edge root extensions.
Weaponry
The Su-47 fighter pilot features 14 hard points (2 wingtip, 6-8 under wing, conforming underfuselage 6-4). The hard points are equipped with R-77, R-77PD, R-73, K-74 air to air missiles. It is also equipped with air to surface missiles X-29T, X-29L, X-59M, X-31P, X-31A, KAB-500, KAB-1500.
Cockpit
The cockpit's design has focused on maintaining a high level of comfort for the pilot and the pilot the ability to plane in extremely high G-load maneuvers to control.
The aircraft is equipped with a new ejection seat and life support system. The variable geometry adaptive ejection seat is an angle of 60 °, the impact of the high G-forces on the pilot reduced. The chair aerial combat maneuvers with significantly higher g loads can usually be tolerated by the pilot.
The pilot uses a side, low-travel control stick and throttle tensometric.
Landing gear
The aircraft uses a retractable tricycle landing gear with a wheel type for each unit. The smaller nose wheel pulls to the back and the two main wheels to slide forward in the wing roots.
Engine
The Su-47 fighter aircraft powered by two D-30F6 Permian Aviadvigatel turboshaft engines. Around 83.4kN dry thurst can be produced by each motor. The engine is primarily used in short-haul passenger aircraft.
The length and diameter of the fantip 3.98m and 1.05m respectively, motor, while dry weight and the weight of the motor supply 1,550 kg and 1,712 kg. The engine also features a thrust reverser and a low pressure compressor.
Performance
The Su47 fighter aircraft can climb at a speed of 233m / s. The cruise speed is 1.800 km / h. The range and service ceiling of the aircraft 1,782 nm (3,300 km) and 18,000 m respectively. The maximum takeoff weight of the aircraft is 34,000 kg. The wing loading and a maximum g-force of the Su-47 to 360kg / m² and 9g respectively.
