KB SAT (Sovremennye Aviatsionnye Teknologii) of Russia is currently working on a new intermediate jet-powered trainer for the Russian Air Force and perhaps, in the near future, global export customers. Work on this compact platform began in 2007 and the product was unveiled at MAKS 2009. The SR-10 was originally developed in response to a Russian Air Force requirement of 2014 which sought to secure a new basic trainer aircraft. However, this requirement was eventually fulfilled by the Yakovlev Yak-152 (detailed elsewhere on this site). A first-flight for the still-in-development SR-10 occurred on December 25th, 2015 and work on the aircraft is ongoing as of 2017 to which a single, flyable example was been completed to date (2017).
The aircraft seats its crew of two in tandem (one behind the other) with good views offered for both pilots (instructor and student) out over the nose. The single engine installation, buried within the aerodynamically-refined fuselage, is aspirated by small, side-mounted rectangular intakes and exhausted through a single port at the rear of the design. The wing roots extend over the intakes and meet each of the mainplane leading edges. The most unique feature about this Russian aircraft is its forward-swept wing mainplane - each element having a sweep of ten degrees giving the SR-10 a very science- fiction-like appearance. The mainplanes are set just aft of midships and are high-mounted along the fuselage sides. A single vertical tail fin is featured at the rear of the aircraft along with low-mounted horizontal tailplanes, these sporting noticeable anhedral. Ground-running is accomplished by way of a conventional three-legged retractable undercarriage. Overall construction of the aircraft relies heavily on use of lightweight, yet strong, composites.
The SR-10 carries a single Ivchencko AI-25V turbofan engine rated at 3,790lb of thrust. This provides the platform with a maximum speed of 560 miles per hour and cruises at 325 mph. Range is out to 930 miles and a service ceiling of 932 miles is reported. Rate-of-climb is 12,000 feet-per-minute.
Structurally, the SR-10 has an overall length of 31 feet, 5 inches, a wingspan of 27 feet, 6 inches and a height of 11 feet, 7 inches. Gross weight is 5,300lb with a Maximum Take-Off Weight (MTOW) of 6,000lb.
July 2017 - KB SAT has proposed an unmanned version of its manned AR-10 intermediate trainer. This variant is set to be designated as the AR-10 "Argument" and feature a pair of external underwing hardpoints for munitions-carrying. Other changes include a V-style, double-finned tailplane arrangement.
October 2017 - Reports indicate that the SR-10 has been selected by the Russian Air Force to replace its aging fleet of Czech-originated Aero L-39 Albatros jet-powered trainers currently in service. Deliveries are set to begin sometime in 2018.
