The Izdelie 181 (Ukrainian: Виріб 181, Russian: изделие 181), occasionally referred to unofficially as An-181, was a Soviet experimental aircraft designed during the 1980s by Antonov.
History
Development of the Izdelie 181 was discontinued when funding ceased after the Soviet Union dissolved. This aircraft is notable for its distinctive arc-shaped wing, classified as a channel wing. Additionally, it features side-by-side seating arrangements, a fixed tricycle undercarriage, and a V-tail configuration. The propulsion system transmits power from the engine through drive shafts and deflection gearboxes to two-blade propellers. Registered as СССР-190101, the sole prototype is now displayed at the State Museum of Aviation in Ukraine. The channel wing concept had earlier been explored by Willard Ray Custer in the United States with similar aircraft designs.
