Sukhoi Su-35

| Thursday, June 23, 2011 | 0 comments

The Sukhoi Su-35 (NATO reporting name: Flanker-E) is a Russian heavy, long-range, one-seat multirole fighter. Developed from the original Su-27 air superiority fighter, it was originally designated Su-27M and later renamed Su-35 by Sukhoi. Due to the similar features and components it contains, the Su-35 is considered a close cousin of the Sukhoi Su-30MKI, a modernized Su-30 variant for India. The Su-35 is a 4++ generation aircraft employing technologies of the fifth generation. They make it superior to all other 4th generation fighters now under development worldwide. In 2009-2015, thanks to these technologies, the Su-35 will dominate the world market, outperforming other proposed multi-role fighters.

In terms of engineering, the engines are substantially modified AL-31F production engines employing fifth-generation technologies. They use a new fan, new high and low pressure turbines, and a new digital control system. A provision is made for using a vectored thrust nozzle. The modernization has increased the engine special mode thrust by 16%, up to 14,500 kgf. In the maximum burner-free mode it reaches 8,800 kgf. Compared to today’s AL-31F engines, their capabilities will grow substantially, by 2 to 2.7 times. For instance, the between-repair period will grow from 500 to 1,000 hours (the operating period before the first overhaul is 1,500 hours). The designed period will vary between 1,500 and 4,000 hours.

In addition to the armaments onboard the modern Su-30MK, it is planned to additionally arm the Su-35 with new types of air-to-air and air-to-surface guided missiles, including long-range types. The maximum ordnance load of the Su-35 is 8,000 kg. This is placed in 12 weapon stations.
