An annular wing particularly suited for use in supporting in flight an aircraft characterized by the absence of directional stabilizing surfaces. The wing comprises a rigid annular body of a substantially uniformly symmetrical configuration characterized by an annular positive lifting surface and cord line coincident with the segment of a line radiating along the surface of an inverted truncated cone whereby a decalage is established for the leading and trailing semi-circular portions of the body, relative to instantaneous line of flight, and a dihedral ...
In combination with a tailless aircraft an improved wing when in flight having a direction of flight, a climb angle, a geometric center, an aerodynamic center, and a center of gravity located forwardly of the aerodynamic center of the wing, relative to the direction of flight, comprising: an unitary annular body defining an annular air foil symmetrically related to all planes passing through the geometric center thereof, and characterized by wing sections of uniform size and shape, each of said sections having a chord coincident with a segment of a line ...
