Abstract
A lift apparatus using the method of blowing air over the upper surface of the apparatus to generate lift by virtue of the balance of outside pressures against the body of the apparatus. It does this by using the expansion characteristic of supersonic gas stream in a divergent space to create low pressure above the upper surface and to maintain the attachment of the stream to the surface. For power source, it uses the hybrid internal combustion engine of a co-pending invention in its jet operation mode to jet the air. And it solves the working substance supply problem by recycling.
