The SR-10 debuts at the Zhukovsky Show
A new Russian aircraft made its debut at the MAKS 2017 International Fair which took place near Moscow last week. The SR-10 school developed by the SAT is a Russian acronym for "Modern Aviation Technologies".
The KB SAT SR-10:
This newcomer was developed by a Russian private engineering firm called KB SAT, the aircraft has a reverse wing (FSW). The development of the SR-10 school aircraft began in 2007 by the Modern Aviation Technology Design and Engineering Office (KB SAT). The development of it took a few years behind due to funding problems, now resolved. The first appearance of this project dates from the Moscow Air Show in 2009, with the presentation at the time of a scale model.
The SR-10 is made entirely of composite materials and uses the technology of the inverted wing which offers better handling thanks to its angle of attack. The FSW is characterized by significant directional instability around the yaw axis and is subject to aeroelasticity problems at the tip of the wing and is quite unstable under stall conditions. Several demonstration machines such as the Grumman American X-29 and the Sukhoi Su-47 "Berkut" have in the past demonstrated the characteristics of this type of aerodynamics. So far, this technology has never been taken up for the production of an aircraft because of structural instability.
The SR-10 has a maximum take-off weight of 2,700 kilograms, its maximum speed is 900 km / h (it is capable of flying over a very wide range of speeds), and its range is 1,500 kilometers . The aircraft is powered by a Saturn AL-55 NPO. Its aerodynamic configuration with the inverted wing allows to perform all the figures of the high aerobatics characteristic of the apparatuses of the generations 4 and 4 +. According to its designer, the SR-10 will be able to compete with the current airplanes schools.
Soon in the Russian army ?
The Russian Air Force intends to use the SR-10 as a direct replacement for the Aero L-39 Albatros for the initial and main training courses. The Yak-130 will be confined to weapons training.
