Bisnovat SK-2

A direct result of high-speed wing research conducted at the TsAGI (Central Aerodynamics and Hydrodynamics Institute) by a team headed by Matus Bisnovat, the SK-2 single-seat fighter was evolved from the SK (skorostnoye krylo, or high-speed wing) aircraft tested during the winter of 1939-40. The SK was, effectively, the smallest possible airframe capable of accepting a 12-cylinder Vee-type engine, every effort being made to reduce drag (eg, a flush-fitting cockpit canopy which could be raised, together with the pilot's seat, for takeoff or landing). The SK-2, flown in October 1940, had a similar small-area wing and 1050hp Klimov M-105 12- cylinder liquid-cooled Vee-type engine, but an orthodox cockpit, conventional carburettor and oil cooler air intakes, revised vertical tail surfaces and an armament of one 7.62mm and two 12.7mm machine guns. The SK-2 was of all-metal construction with dural pressed sheet stressed wing skinning and a semi-monocoque fuselage. Flight test results were allegedly promising, but not sufficiently so to warrant displacing established fighter types in production.
