Yakovlev AIR-9

The Yakovlev AIR-9, with its AIR-9bis refinement, was a two-seat sport aircraft designed and built in the Soviet Union in the early 1930s. It was a low-wing monoplane with wooden wings, a welded steel tube fuselage and a 100 hp Shvetsov M-11 radial engine. The first design had open cockpits, landing flaps and automatic leading-edge slats and was submitted to a safe aircraft competition but not taken further. It was reworked in 1934 with sliding canopies, and the AIR-9bis was shown at the 1935 Paris and Milan airshows and used for a women's altitude record in 1937.
