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 ...
[ I claim:] [1.] An aerodynamic force-producing apparatus with the associated force direction defined as the up direction, comprising:(a) a body having an upper surface with respect to said up direction, and said upper surface having a predetermined geometry, a first periphery and a second periphery;(b) convergent-divergent nozzle means disposed atop said upper surface along said first periphery for blowing a supersonic gas stream across said upper surface and together with said geometry of said upper surface for causing said gas stream to flow contiguou...
