Abstract

A non contact lifting device comprising a body including a flat lower surface radially outward of a first angled impingement surface and a plenum with an outwardly facing annular outlet including a nozzle throat. At least one fluid inlet port communicates gases to the plenum. A central lower surface sits below the plenum. The nozzle throat geometry and fluid pressure supplied in use through the fluid inlet port cause a supersonic gases jet to exit the nozzle throat in a radially outwards direction into an area below the first angled impingement surface. The geometry of the first angled surface in a region between the nozzle throat and intersection of the first angled surface and the flat lower surface of the body, maximizes the entrainment effect of gases under the central lower surface by carrying the gases downstream in a radially outwards direction and setting up a toroidal vortex in the area under the first angled surface.
