Sukhanov's "Discoplan II"

(1960)

The photo s shows the 1960 version, the Discoplan 2. These photos are very heavily retouched, but the aircraft's structure appears to have been based on a wooden or steel truss covered with lacquered canvas -- standard lightplane and glider construction. Apparently the disc-shaped vertical "fin" was designed to revolve on a horizontal axis like a bicycle wheel -- possibly to provide some sort of gyroscopic stabilization to the aircraft's control system via a system of cables and struts.
