ABSTRACT:
An aerodynamic device which can take off and land vertically is disclosed. The device comprises a non-rotating central body surrounded by an outer rotating disc concentric with the central body. A plurality of jets affixed to the disc are selectively vectorable between a vertical, tangential, or radial direction. One or more reaction jets are affixed to the central body and vectored to counteract a torque generated by the rotating disc. The jets affixed to the central body so that as the disc rotates relative to the body the jets are rotated in a counter direction to have a common longitudinal axis with the central body. Pairs of radial vanes disposed along the upper and lower walls of the disc are hinged to their respective walls, and when open impart a lifting action to the disc. The pairs of upper and lower vanes are interconnected by a slot which makes the lifting action of the vanes aerodynamically more effective. The slots also serve as a means for causing the disc to rotate relative to the central body in the event of a total power failure and give the device a degree of stability and control during a non-powered decent.
