Su-35 - Big Brother to the Su-27

A Russian 4++ Generation, heavy class, long range, multi-role, single-seat aircraft. It is a redesigned variant of the Su-27, with an upgraded airframe and improved avionics, weapons, and engines.

The Su-35 is basically a modernized version of the Su-27, built in the 1970's, to fill the gap until the new PAK FA T-50 aircraft becomes operational. The PAK FA can be comparable with the American F-22 and F-35. It was presented to the general public in the MAKS 2007 airshow.

Improvements from Su-27M...

The Su-35 has larger wings and engine intakes. The airframe of the Su-35 is reinforced with the use of composite materials (strong and lightweight) like titanium alloys that extends the aircraft's service life by about 4000-6000 hours and lengthens the time period between overhauls (Milavia). The front radar signature of the Su-35 is also significantly reduced.

An advanced digital fly-by-wire (KSU-35) is also introduced into the plane and a rear-locking radar is included for firing Semi-Active Radar Missiles.

The canards from the Su-27M Super Flanker and the speedbrake are also removed. To match or surpass the maneuverability of canard-equipped aircraft, the Su-35 uses its new engine and the digital fly-by-wire system.

The maximum payload, however, has not changed.

New engines...

The new 117S engines of NPO Saturn powers the Su-35. This engine provides 16% more thrust compared to the Su-27's AL-31F. Engine service life and time between overhauls has also been increased.
