--The Weser Fluke P.1003 is a double-seat vertical take-off and landing aircraft designed by Weser Fluke Zeikbau in Germany in 1938.
--With the support of the German Ministry of Aviation, which showed an interest in military tilt rotor aircraft, this aircraft was developed with Dr. Adolf Rohrbach as the chief designer.
――The most characteristic part of this aircraft is that the wings are rotated 90 degrees from the middle of both wings, the propeller is directly above, vertical takeoff is performed in the same way as a helicopter, and after takeoff, the gradually rotated wings are in a horizontal state. I returned to to secure the driving force forward.
--The main wing is a high wing type to secure the clearance of a huge propeller with a diameter of 4 meters, it is operated by one Daimler-Benz DB600 series engine mounted on the back of the cockpit, and the intake is from the air intake at the bottom of the nose. It was done.
――The landing gear was retractable on the fuselage, and the cockpit was tandemly arranged so that two people could board the front and rear seats.
――P.1003 was an aircraft designed with a novel concept, but there was no prospect of developing a complicated power transmission mechanism that operates the propellers at both wing tips with one engine, so we planned without making a prototype. It ended with.
