History

The izdelie 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, known as a channel wing; in addition, the aircraft has side-by-side seating, a fixed tricycle landing gear configuration, and a V-tail. 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]
