History

The Antonov An-181 (or product 181) project was terminated due to the lack of funds following the collapse of the Soviet Union. An interesting feature of the plane is its unusual arc-shaped wing, a so-called Channel wing. The aircraft has two seats next to each other, a tricycle fixed landing gear configuration, 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 aeroplanes with the same wing concept in the USA.[1]
