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.

Claims

1. A heli-hover amphibious craft, comprising:

a main hover craft fuselage body structure including a single hull provided with a deck, said hull being defined by a compartmental under base cavity extending downward with divisional and perimeter walls formed by air cushion containing means for containing suspension air, said fuselage body being provided with at least one built-in duct extending through said deck to said base cavity;

at least one deck mounted fan means for delivering pressurized air through said duct;

a superstructure attached to said fuselage body;

at least one horizontally rotating heli-rotor assembly supported well above said deck by said superstructure, said heli-rotor assembly being driven by a substantially vertically fixed shaft;

anti-torque means mounted on an aft end of said fuselage body; and

a drive means operatively connected to said heli-rotor assembly and anti-torque means for propelling the craft.

2. A heli-hover amphibious craft according to claim 1, including a counterrotating rotor positioned co-axially with said heli-rotor assembly.

3. A heli-hover amphibious craft according to claim 1, including an additional heli-rotor assembly, wherein said rotor assemblies are positioned in a tandem configuration.

4. A heli-hover amphibious craft according to claim 3, including additional heli-rotor assemblies wherein said rotor assemblies are positioned in a quad configuration.

5. A heli-hover amphibious craft according to claim 1, wherein said anti-torque means comprises a tail rotor attached to an elevated tail structure on the aft portion of the fuselage body.
