The Su-35 chassis has been reinforced because of the increased takeoff and landing weight of the aircraft. Its functions are performed by an active rudder. Other aerodynamic refinements include a height reduction of the vertical stabilizers, a smaller aft-cockpit hump.Īmong the Su-35 design features, worthy of note is the absence of an overhead brake flap, a standard characteristic of the Su-27. These improvements removed the need for canards and saw the abandonment of the 'tandem triplane' featured on several Su-27 derivatives. Technological advancements have produced more compact and lighter hardware, thus shifting the centre of gravity to the aircraft's rear. But unlike the Su-30MKI it will feature no canard fins. The fighter also has an integral oxygen generation unit to enhance its self-contained operation capabilities.Īerodynamically it is similar to the Su-27. Another first for the aircraft of the type is the Aerosila TA14-130-35 gas-turbine auxiliary power unit (APU). In addition, the Su-35 is the first in the Flanker family able to carry two drop tanks 2,000 litres each. The fuel load grew by more than 2 t, totalling 11,500 kg. The central and side tail booms have extra room to house fuel. The rudders were enlarged and now have the vertical trailing edge, while the tail tips are made of metal. The upper surface of the fuselage centre section lacks the air brake, with his job now being handled by differentially operated rudders. The aft-cockpit avionics bay was shortened, and the remaining volume now houses an extra fuel cell. The reduced weight raised the maximum takeoff weight to 34.5 tonnes.

The reinforced airframe sees extensive use of titanium alloys.

the fighter got an improved airframe, which dramatically increased its service life to 6,000 hours, 30 years of operation (the time before the first test and recondition and the between-repairs period has been increased to 1,500 hours, or 10 years of operation).

Su 35 is a considerably modified Su-27 fighter.
