A new trainer jet designed by a private Russian design bureau KB-SAT has completed its maiden flight on Dec. 25 from an airfield near Vorotynsk, in the Kaluga Region, Russia.
Dubbed the SR-10, the new trainer follows the heritage of the Sukhoi Su-47 Berkut supersonic demonstrator and features an unusual moderate forward swept wing with leading edge root extension.
The aircraft is designed to achieve high maneuverability, high structural strength and minimum airframe weight. The forward swept wing enable maneuvering at wide range of angle of attack.
The all composite airframe has three sections. The nose section with the avionics, front landing gear bay and the pressurized tandem seat cockpit.
The middle part of the airframe has an equipment compartment behind the cockpit, the hull fuel tank, side air intakes. The side beams with attachment points of main gears are located along the sides.
The aft part of the fuselage includes: the engine compartment, the life support and air conditioning systems.
The jet trainer will be capable of providing both initial and basic flight training with its 200-900 kmph speed range and operating altitude of 6 km.
The present Yakovlev Yak-130 (Alenia M-346) advanced jet trainer operated by Russian Air Force can operate at an altitude of 12 km and at speeds up to 1000 kmph.
The SR-10 has landing and take off speeds of 185 and 190 kmph respectively, and is equipped with Zvevda K-93 zero-zero ejection seat that is safe up to 900 kmph speed.
Powered by a single AI-25TL turbofan engine, the SR-10 has a maximum take off weight of 2,700 kg. A more powerful AI-55 engine is also being studied.
The first prototype has an analog cockpit and a glass cockpit with LCD screens is optional. The aircraft will also have an aerobatic version for aerial display and sports events.
In 2014, SR-10 had lost a Russian Defense ministry tender for basic trainer aircraft, which was won by the Yak-152 turboprop trainer.
The first forward swept wing aircraft X-29 was developed by the Grumman Corporation in 1980s. The aircraft first flew in 1984 and was controllable at 67 degrees of AOA.
The Sukhoi developed Su-47 first flew in 1997 and aided in development of the PAK-FA stealth fighter.
