MAKS 2017 - SU-57, The Pinnacle of Russian Air Domination! - HD 50fps

Yesterday (5/12/2017), the SU-57 made the first flight to test the new 'izdeliye 30' engines!

In this video, Sergey Bogdan and Sergey Chernyshev (Сергей Богдан, Сергей Чернышев), both first-class test pilots of the Sukhoi Company perform an amazing flight display with the latest and most modern russian 5th generation fighter aircraft, the Sukhoi SU-57 during MAKS 2017 at the Ramenskoe airport in Zhukovskiy.

The Sukhoi Su-57, previously designated T-50 (Сухой Су-57 / T-50) is a single-seat, twin-engine, stealth fighter aircraft with multirole capability but designed for air superiority and attack operations. This jet aircraft is the product of the PAK-FA (ПАК-ФА, Перспективный авиационный комплекс фронтовой авиации, literally "Prospective Aviation Complex of Frontline Aviation"), a fifth-generation fighter programme of the Russian Air Force. The first prototype performed the maiden flight on January 29, 2010. Deliveries of production aircraft to the Russian Air Force are expected to begin in 2018.

The fighter is intended to succeed the MiG-29 and Su-27 in the Russian Air Force and to serve as the basis for the Fifth Generation Fighter Aircraft (FGFA) while complementing the recently built fleets of SU-35S and SU-30SM. The initial production batch are to be delivered with a highly upgraded variant of the AL-31F engine, extensively used by the Su-27 family while a totally new turbofan jet powerplant is being designed from scratch. In fact the first prototype of this engine has already been fitted into a SU-57 airframe and has already begun testing.

The Su-57 has a blended wing body fuselage and incorporates all-moving horizontal and vertical stabilizers. The aircraft incorporates thrust vectoring nozzles and has adjustable leading edge vortex controllers (LEVCONs) that improve high angle of attack behaviour. The advanced flight control system and thrust vectoring nozzles make the aircraft highly maneuverable in both pitch and yaw, enabling it to perform post-stall maneuvers such as the Pugachev's Cobra and the Bell maneuver, along with doing flat rotations with little altitude loss. The aircraft's high cruising speed and normal operating altitude is also expected to give it a significant kinematic advantage over older fighter jet generations.

The aircraft will make extensive use of composites; on the first prototype, composites comprise 25% of the structural weight and almost 70% of the outer surface. Weapons are housed in two tandem main weapons bays between the engine nacelles and smaller bulged, triangular-section bays near the wing root. Internal weapons carriage eliminates drag from external stores and enables higher performance compared to external carriage, as well as enhancing stealth. This is the same trick used by the American F-22 Raptor and F-35 JSF/Lightning II. Advanced engines and aerodynamics enable the Su-57 to supercruise, which is the ability to maintain sustained supersonic flight without using afterburners. Combined with a high fuel load, the fighter has a supersonic range of over 1,500 km, more than twice that of the Su-27. In the Su-57's design, Sukhoi addressed what it considered to be the F-22's limitations, such as its inability to use thrust vectoring to induce roll and yaw moments and a lack of space for weapons bays between the engines, and complications for stall recovery if thrust vectoring fails.
