Product 181 (Ukrainian: Виріб 181, Russian: Изделие 181), was a Soviet experimental aircraft, built by OKB Antonov in Kyiv at the end of the 1980s. An interesting feature of the plane is its unusual arc-shaped wing, a so-called Channel wing.


The Antonov An-181, or also called Product 181, is an experimental aircraft built by OKB Antonov in Kiev in the late 1980s. Due to the collapse of the Soviet Union, the project was terminated because of the lack of funds. An interesting feature of the aircraft are its unusual curved wings, the so-called channel wings. The aircraft has two seats next to each other, a conventional fixed landing gear, a V-tailplane, and high-wing equipped with a channel wing in the area of the propellers. Power from the engine is delivered by means of drive shafts and deflection gearboxes to the two-blade propellers. The aircraft received the registration СССР-190101 and is exhibited in the State Museum of Aviation of Ukraine. Willard Ray Custer had previously built airplanes with the same wing concept in the USA.[1]
