Patent ID: 8398015

Claim:
An aircraft capable of vertical and horizontal flight without use of a fixed wing, the aircraft comprising: one or more means of propulsion for achieving horizontal flight; an aircraft cabin generally having a front end, a rear end, a top side and a bottom side; at least two sets of wings for achieving vertical lift configured to rotate about respective axes in a horizontal plane that are: (i) laterally spaced apart in a horizontal plane of the aircraft, (ii) parallel to each other, and (iii) positioned adjacent one or more frame portions; wherein each said set of wings is controlled independently of each other said set of wings; each of said one or more frame portions defining a continuous surface, having a semi-circular cross-section, the semi-circular cross-section extending from a point directly above the axis of its respective wing, and to a position directly below the same axis, at least two of said semi-circular frame portions being connected by a stationary horizontal frame member; and an engine for driving each of said at least two sets of wings so that, as they spin, each said wing moves sequentially upwards inside its respective frame portion, and downwards outside its respective frame portion to drive air in a downward direction thereby providing vertical lift for the aircraft.
