Yatsenko I-28

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]
