PAK FA, Sukhoi

Sukhoi PAK FA is the fifth largest battlefield conducted by the Sukhoi OKB of the Russian Air Force. PAK FA is fully developed aimed at replacing the MiG-29 Fulcrum and SU-27 Flanker on a Russian custodian and using it as the basis of the Project / HAL FGFA project (developed by India). As a fifth generation of jet fighter, we have been specifically competing with Mr F-22 Raptor and America / Britain F-35 Lightning II.

The current prototype, called T-50, made the first aircraft on 29 January 2010. It was conducted by the Sukhoi testing pilot Sergey Bogdan and lasted for 47 minutes. It is the second flight that takes place on 6 February. As of August 2010, they made 17 flights and in mid-November 2010, the number was 40.

In the late 1980's, the Soviet Union indicated the need for future flights to return May 29 and Su-27 in the previous service. Two projects were raised to meet this need, Sukhoi SU-47 and Mikoyan Project 1.44. In 2002, Sukhoi was chosen to lead a new aircraft design. PAK-FA will install technology from both Su-47 and MiG 1.44.

Design

Although most information about PAK FA is divided, it is believed to communicate with the people of the Russian Air Force department and the protective service (less than F-117), has the ability to shine, adjust the next generation of airline air, air and air, In the air conditioning, including the AESA radar with a 1500-element array and will have "inserted intelligence".

PAK FA is expected to utilize two Saturn 117S engines in its first aircraft. 117S (AL-41F1A) is a huge AL-31F enhanced based on AL-41F aimed at enabling Su-35BM, producing 142 kN connections with afterburner and 86.3 kN dry. In fact, PAK-FA is already using the new engine completely in its first move, as explained by NPO Saturn. Engine is not supported on Saturn 117S. The engine produces a larger system and a complicated automatic system, facilitating easy travel systems. It is expected that each engine will automatically be able to independently vector its top up, down or next. Installing a single vectoring engine with one down can produce a potential argument. Therefore PAK FA can be the first fifth-generation fighter of a 3-D generation full of vectoring that complies with all three airline directions: pitch, yaw and roll. These engines will include steps to minimize infrared and RCS.

The first driving video shows that PAK-FA / T-50 does not have normal rudders, their mobile tailors are completely moving. This unique mill tailor design is similar to the V-tails using Norroprop YF-23 in 1990, but it is compiled with low-cost computers (such as F-22). T-50 has a leading jet engine company called a signature control signature.

Composites are widely used for T-50 and comprise 25% of its weight and less than 70% of the outer space. It is estimated that content of the titanium alloy of fuselage is 75%. Sun's concern for reducing the radar cross-section (RCS) and pulling is also reflected in the provision of two major weapons in the major events between the engine and the nacelles. Each is thought to be 5m long. Main bays are sold for bulged, more than triangular in the wing of the wing.
