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 fl...
An aircraft comprising in combination a lifting body and a jet flap at the trailing edge thereof, said aircraft having a substantially delta-shaped planform, a nose, and a wide trailing edge opposite said nose, movable flap means forming part of said trailing edge, propeller means for producing a propulsive thrust solely as a result of the reaction of a plurality of rotating blades with the surrounding atmosphere, said blades being mounted on a hub rotatable on a first axis, and means for tilting said first axis about a second axis located above, and ext...
