| Abstract: |
A heli-hover amphibious craft which includes a main hover craft fuselage body structure including a single hull provided with a deck. The hull is defined by a compartmental under base cavity extending downward with divisional and perimeter walls formed by air cushion containing structure for containing suspension air. The fuselage body is provided with at least one built-in duct extending through said deck to said base cavity. At least one deck mounted fan is provided for delivering pressurized air through the duct. A superstructure is attached to the fuselage body. At least one horizontally rotating heli-rotor assembly is supported well above the deck by the superstructure, with the heli-rotor assembly being driven by a substantially vertically fixed shaft. An anti-torque device provided on an aft portion of the fuselage body. A drive mechanism is operatively connected to the heli-rotor assembly and the anti-torque device for propelling the craft.
