Sukhoi T 50 PAK FA Stealth Technology
Показать описание
The Sukhoi PAK FA T 50 is a twin-engine jet fighter being developed by Sukhoi for the Russian Air Force. The Sukhoi T-50 is the prototype for PAK FA.[10] The PAK FA is one of only a handful of stealth jet programs worldwide.
The PAK FA, a fifth generation jet fighter, is intended to be the successor to the MiG-29 and Su-27 in the Russian inventory and serve as the basis of the Sukhoi/HAL FGFA being developed with India. The T-50 prototype performed its first flight 29 January 2010. Defense Ministry have openly stated that it features stealth technology and has the capability to supercruise,[6] and incorporate advanced avionics such as an Active Electronically Scanned Array (AESA) radar and an artificial intelligence system. It is to be outfitted with the next generation of air-to-air, air-to-surface, and air-to-ship missiles. The T-50 has a blended wing-body design and incorporates all-moving vertical stabilizers and horizontal elevators. The aircraft has wing leading-edge devices above the jet engine (LEVCONs) designed to control vortices generated by the leading edge for improved behaviour at high AOA. The two engines incorporate 2D thrust vectoring nozzles canted at an angle, similar to the configuration on the Su-35S. Differential actuation of these nozzles can produce rolling and yawing moments. The aircraft inlet incorporates variable intake ramps for increased supersonic engine efficiency and retractable mesh screens to prevent foreign object debris from being ingested into the engines.
