Abstract
A novel drive for a lifting platform utilizing a simple propeller, impeller, or gas turbine is disclosed. The axial air rotation from the drive is eliminated in order to permit the development of a partial toroidal vortex which efficiently maintains a raised air pressure zone beneath the lifting platform. The axial components are eliminated by means such as flow straightening vanes, which may also serve to control lateral motion of the lifting platform. The system can also be easily modified to function as an attractor device. Overall, the present invention explores the effect of vortices, both cylindrical and toroidal, and seeks to optimize their effects.
