Analysis of operation of ground-effect machines (GEM); defined as devices which operate in close proximity to earth's surface separated by cushion or layer of air; propulsion and control must be of aerodynamic nature; main categories of GEM's established are ram wing, peripheral seal, such as non-recirculating annular jet, recirculating labyrinth seal, diffuser, peripheral air leakage, such as plenum chamber, and levapad; basic principles involved.
