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 aerodynam...
[ 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 w...
