The Su-35 has long been a brand name in the aviation world. Since 1992, an export version of the Su-27 fighter (created under the order of the Russian Air Force) has been demonstrated at international air shows. At the turn of the millennium, Su-35 fighters participated in the tenders of Korean and Brazilian air forces. By the mid-decade of the new century, a general concept emerged of a considerably modified Su-27 fighter, which retained the name of Su-35. What is new in the Su-35? First off, the fighter will get an improved airframe, which will dramatically increase 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). Aerodynamically it is similar to the Su-27. But unlike the Su-30MKI it will feature no canard fins. All the three channels will have electrically signaled control without mechanical cabling. The use of a new integrated control system (developed by MNPK Avionika Moscow-based Research and Production Association) simultaneously performing functions of several systems – remote control, automatic control, limiting signals system, air signals system, chassis wheels braking system – will enhance the fighter’s handling capability and maneuverability. Among the Su-35 design features, worth of note is the absence of an overhead brake flap, a standard characteristic of the Su-27. Its functions are performed by an active rudder. The Su-35 chassis has been reinforced because of the increased takeoff and landing weight of the aircraft. For the same reason, the front bearing has two wheels. The improved radar stealth reduces the reflectance of the Su-35 in the X radio waveband and in the angle range of ±60°. Another important difference of the Su-35 from predecessors from the Su-27 family is the use, in its power plant, of new engines with an increased thrust. Those engines, known as 117S, have been developed by NPO Saturn Research and Production Association. 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. The 117S engines will be co-produced by Ufa-based Motor Building Association and Rybinsk-based NPO Saturn Research and Production Association. The first production 117S engines were delivered to KnAAPO in early 2007 for testing on the first experimental Su-35 aircraft.
