Lifting body aircraft for v/stol service

Abstract From the Canadian patent

Augmentation of aerodynamic lift for a given amount of power in STOL operation of a V/STOL aircraft is achieved by combining the unique features of a lifting body with those of a "jet flap", i.e. an aerodynamic mechanism in which a slipstream is directed over a deflected flap. Specifically a movable, flap is located on the trailing edge of the lifting body and, a tiltable rotating blade propeller which propels the aircraft, in the normal manner in cruising may be tilted, in low-speed, flight, in order to direct air toward the leading edge of the flap and over the upper surface thereof. The movement of a large mass of air at a higher velocity over the upper surface of the flap maintains the …
