Abstract

A ground effect flying craft utilizing a pressure cavity (10) for low speed support on a static air cushion. The cavity is bounded by a streamlined aft body (18), a fore body (24), and side plates (22) which allow for low drag and high lift at cruise speed on a dynamic air cushion. Static lift pressure and dynamic thrust are provided by a fixed dual purpose propulsor (20'). Flow diverting devices or auxiliary power units are not needed for transition from static lift to dynamic flight.
