A hybrid aircraft is taught having VTOL, R-VTOL and S-STOL capabilities. The aircraft has a lifting body hull and four wing sections arranged in tandem which are pivotally moveable about their neutral axis. Each wing section has mounted thereon a pivotal propeller-rotor assembly for providing thrust substantially in a range between horizontal and vertical. The wings and propellers are integrated to the hull by an outrigger designed to be very stiff and to distribute forces from the wings and propellers to the hull. The hull is shaped to provide aerodynamic lift in an airstream and to facilitate construction by minimizing the number of panels of differing curvature required. The hull is formed of a pressure tensioned frame covered with semi-rigid panels, a lower cladding frame and bow and stem cladding nose cones. The semi-rigid panels covering the frame are formed of gas-tight and abrasion resistant laminate material and are connected to the frame by means of an interface rib and latch system. The frame is formed of a plurality of curved elongate segments arranged in series orthogonal to the long axis of the hull and connected by means of torsion members. A turbo-electric drive system can be used to drive the aircraft. An advanced hybrid aircraft is also described having about 8 to 12 high speed fans in place of the propeller-rotors.

[ I claim:] [1.] An aircraft comprising: a lifting body hull, a plurality of wings spaced about the hull including a left-side forward wing, a left-side rear wing, a right-side forward wing and a right-side rear wing, each wing being shaped as an airfoil and mounted to be pivotally moveable about its neutral axis, each wing being pivotable independent of each other wing and a propelling means mounted on each wing and being pivotally moveable at least between a position in which it is disposed to provide thrust substantially vertically and a position in which it is disposed to provide forward thrust, each propelling means being pivotable independent of each other propelling means and independent of the pivotal movement of the wing to which it is attached.
