Focke-Wulf Triebflügel Aircraft   AH48A001

The Focke-Wulf Triebflügel, or Triebflügeljäger, literally meaning “thrust-wing hunter”, was a German concept for an aircraft designed in 1944, during the final phase of World War II as a defence against the ever-increasing Allied bombing raids on central Germany
The design was particularly unusual. It had no wings, and all lift and thrust were provided by a rotor/propeller assembly 1/3 of the way down the side of the craft (roughly halfway between the cockpit and tailplane). When the plane was sitting on its tail in the vertical position, the rotors would have functioned similarly to a helicopter.[2] When flying horizontally, they would function more like a giant propeller.
The three rotor blades were mounted on a ring assembly supported by bearings, allowing free rotation around the fuselage.[2] At the end of each was a ramjet. To start the rotors spinning, simple rockets would have been used. As the speed increased, the flow of air would have been sufficient for the ramjets to work and the rockets would expire. The pitch of the blades could be varied with the effect of changing the speed and the lift produced. There was no reaction torque to cause a counter rotation of the fuselage, since the rotor blades were driven at their tips by the ramjets. Fuel was carried in the fuselage tanks, and was piped through the centre support ring and along the rotors to the jets
