Abstract
A novel means of stability for a lifting platform utilizing toroidal vortex airflow through air guide means. A toroidal vortex created by the airflow means efficiently maintains a raised air pressure zone beneath the lifting platform or body. Airflow is directed downwards by means of air guides, which serve to produce lift and control rotational motion of the lifting platform to achieve stability of the body during operation. The system can also be easily modified to function as an attractor device. Overall, the present invention explores the uses of vortex airflow towards maintaining rotational stability.
