Abstract:
1. A tilt wing and short takeoff and landing (V/STOL) aircraft having a tall (vertical) fuselage of streamline shape in plan view with its chord pointing forward exhibiting variable area with height above the ground having a right side surface, a rounded leading edge surface, a left side surface and a sharp trailing edge containing at least two sets of aero-surfaces disposed vertically along the trailing edge, each set consisting of at least two elements, one on each side of the fuselage, freely rotatable about a line parallel to the fuselage trailing edge to be deployed during horizontal cruise flight to act as rudders when both sets move together in the same direction, said set acting as aero-brakes when elements of the sets are operated differentially, and said set acting as pitch control of the aircraft when the respective vertical sets are operated at different differential amounts, a single wing near the top of the tall fuselage, the span of said wing being equal distance on each side of and orthogonal to the chord of said fuselage, freely rotatable about an axis parallel to the ground and orthogonal to the chord of said fuselage to facilitate pointing the chord of said wing vertical for takeoff and landing operations and in a horizontal direction for horizontal flight having a lower surface, leading edge surface, upper surface and a sharp trailing edge with at least two sets of aero-surfaces one set on each side of the fuselage each set consisting of at least two elements one on the top surface of the wing and the other on the bottom surface of the wing both freely and independently rotatable about an axis essentially parallel to the wing span said sets being spaced equidistant outboard of the centerline on respective sides of the fuselage, in level cruise flight acting as conventional ailerons when said elements are moved together in opposite directions on each side of the fuselage, and said elements acting as lift augmentation devices when operated together in the same direction on both right and left of the fuselage and said elements acting as aero-brakes when said elements are operated differentially on respective sides of the fuselage, said wing having boom mounted aero-surfaces fixedly mounted to the center of the tilt wing and engine structure extending in the direction of the wing chord aft of the trailing edge having aero-surfaces acting as conventional elevator and rudder in horizontal cruise flight, a propulsion means consisting of an engine and tractor mounted variable pitch propeller extending forward of the leading edge of the tilting wing points up during takeoff and landing and horizontal during horizontal cruise flight.
