Abstract: An unexpectedly high 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 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 air flow over the flap in an attached condition, and entrains and energizes the lower-velocity boundary layer on the airfoil forward of the flap, thereby producing an augmentation in lift. The lifting body lends itself especially to lift augmentation in that, for a given lifting surface area, the low aspect ratio of the lifting body gives rise to a much greater lift augmentation than would be afforded by a high aspect ratio surface.

Abstract: An aircraft capable of flying at very low velocities utilizing a wing envelope of an aerodynamic configuration having cells filled with a lighter-than-air gas. In one embodiment the buoyancy of the wing is slightly less than the total weight of the aircraft wherein forward movement is required to provide lift. In another embodiment the buoyancy is greater than the aircraft weight wherein forward motion is required to produce universal control without the release of gas or ballast. The wing envelope is formed of a plurality of trussed members radially extending from an axis producing a plurality of cells covered by a lightweight high strength skin material, the aircraft being characterized by high strength, economy and efficiency of construction and efficiency of lift at low speeds.
