Video Features Sukhoi SU-57 Russian Super Stealth fighter jets performing Amazing maneuver

The Sukhoi Su-57 is a Russian stealth, single-seat, twin-engine jet multirole fighter aircraft. It is designed for air superiority and attack operations

The fighter is planned to have supercruise, stealth, super maneuverability. And advanced avionics to overcome the prior generation fighter aircraft as well as ground and maritime defences.

The prototype first flew on 29 January 2010 and deliveries of production aircraft to the Russian Air Force are to begin in 2018.

Su57 incorporate substantial amounts of composite materials and possess advanced avionics such as active phased array radar and sensor fusion


The Su-57 has a blended wing body fuselage and incorporates all-moving horizontal and vertical stabilizers

The vertical stabilizers toe inwards to serve as the aircraft’s airbrake.

The aircraft incorporates thrust vectoring and has adjustable leading edge vortex controllers (LEVCONs) designed to control vortices generated by the leading edge root extensions, and can provide trim and improve high angle of attack behavior, including a quick stall recovery if the thrust vectoring system fails

The advanced flight control system and thrust vectoring nozzles make the aircraft departure resistant and highly maneuverable in both pitch and yaw

It enables the aircraft to perform very high angles of attack 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 the normal operating altitude is also expected to give it a significant kinematic advantage over prior generations of aircraft.


Pre-production T-50 and initial production batches of the Su-57 will use interim engines, a pair of NPO Saturn izdeliye 117,[N 2] or AL-41F1.

Closely related to the Saturn 117S engine used by the Su-35S

The 117 engine is a highly improved and uprated variant of the AL-31 that powers the Su-27 family of aircraft.

The 117 engine produces 93.1 kN  of dry thrust, 147.1 kN  of thrust in afterburner

Furthermore, It has a thrust to weight ratio of 10.5:1

The two 117 engines incorporate thrust vectoring (TVC) nozzles whose rotational axes are each canted at an angle

In addition similar to the nozzle arrangement of the Su-35S.

This configuration allows the aircraft to produce thrust vectoring moments about all three rotational axes, pitch, yaw and roll.

Thrust vectoring nozzles themselves operate in only one plane; the canting allows the aircraft to produce both roll and yaw by vectoring each engine nozzle differently.

The engine inlet incorporates variable intake ramps for increased supersonic efficiency

And retractable mesh screens to prevent foreign object debris being ingested that would cause engine damage.
