This project of a vertical takeoff and landing aircraft - VTOL (Vertical TakeOff and Landing) - from the Weserflug company is dated 1938. The fuselage of the aircraft is very traditional and is equipped with a standard tail unit. The wings were the original design solution for this project. Approximately half of the cantilever part of each wing could be rotated relative to the center section on special hinge joints. At the ends of the wings, it was supposed to install nacelles with gearboxes equipped with large-diameter propellers. Since the wing was installed in a high-wing style, the propeller could be turned both forward and downward.
It was installed as a vysokoplan, the propeller could be deployed both forward and downward.
The only Daimler-Benz DB 600 engine, driving both propellers, was supposed to be located in the fuselage behind the cockpit. To supply the engine with air, an air intake was provided, which was led into the nose of the fuselage. The chassis of the traditional three-post scheme was retracted into the fuselage. The crew consisted of two people.
Despite the fact that it was a revolutionary idea at the time, the project never went beyond the drawing board.
