ABSTRACT:
An aircraft having a rotor wing which in one position is locked against the irframe for forward flight, and in another position is extended clear of the airframe. In the extended position the wing is rotated and the tip portions are controllable in the manner of a helicopter rotor. A single power source provides propulsive and wing rotation power. In the preferred form the power source is a turbojet engine and the wing is rotated by a tip jet powered drive beam, separated from the wing to avoid aerodynamic interference. For forward flight the drive beam is enclosed in the airframe as the wing is retracted to fixed position.
