The aim of the project was to construct a military tilt rotor aircraft with VTOL characteristics for use in World War II.
[1] At the beginning of 1938 plans for a tilt rotor aircraft were drawn up, and the project, named P.1003, was supported by the Air Ministry.
A single Daimler-Benz DB 600 engine was mounted in the middle of the fuselage, and drive shafts connected the engine to the propellers, which were abnormally large with a diameter of 4 metres, where for a similar aircraft the propellers would have had a diameter of 2 metres.
The initial plans included the aircraft being fitted with retractable landing gear.
[2] For takeoff, the entire outer part of the wing could be rotated 90 degrees so that the propellers pointed straight up, lifting the aircraft off the ground in a manner similar to that of a helicopter.
