ABSTRACT:
A hovercraft capable of free flight having lifting fans driven alternatively by a gas turbine coupled to the fan shafts or by the diverted exhaust gases of jet engines impinging on circumferential turbine blades on the fans. The jet engines normally provide propulsion, but their exhaust may be directed downward to provide lift. Baffles at the various intake and discharge ports control the direction of movement of the craft and contribute to its stability. Retractable wings enhance lift during horizontal flight.
