The Yatsenko I-28 was a 1930s Soviet single-seat fighter designed by Vladmir Yatsenko and first flown in 1939.[1][2] The I-28 was a low-wing cantilever monoplane of mixed construction powered by a 900 hp (671 kW) Tumansky M-87 radial piston engine.[1] It had an enclosed single-seat cockpit with a rearwards sliding canopy.[1] The wing had an inverted-gull shape to reduce the length of the retractable main landing legs.[1] The prototype was destroyed shortly after the first flight but an order was placed for 30 production aircraft.[1] Also ordered was a prototype of an attack version, the I-28Sh.[1] Although the first five production aircraft were completed the programme was cancelled in early 1940.[1]

Le Yatsenko I-28 est un chasseur monoplan, de construction mixte en bois et métal, conçu à la fin des années 1930.
