Appl. No.:

11/308532

Inventors:

Mark Rice - Brinklow MD, US

Assignee:

MARITIME APPLIED PHYSICS CORPORATION - Baltimore MD

International Classification:

B63B 1/24

US Classification:

114272000

Abstract:

The present invention concerns a marine vehicle that derives its lift and control forces and moments from a combination of the following mechanisms; aerodynamic effects on a lifting surface in ground effect, hydrodynamic effects on submerged hydrofoils, planing forces on deployed winglets, and hydrostatic effects on submerged elements. The portion of the overall lift and control forces that is contributed by each mechanism varies as a function of vessel speed. The hydrofoils may be subcavitating, supercavitating, transcavitating or superventilated. The three lift and control mechanisms are individually found on existing Wing-In-Ground Effect (WIG) vehicles, hydrofoil vessels, and multi-hull vessels but have not previously been combined in the manner described. The present invention combines these three elements to achieve high lift-to-drag ratios, low fuel consumption, good maneuverability, low noise, low vessel draft, low vessel motions, and operation in higher sea states at all relative headings to the wind and waves. Applications of this craft include both civilian and military uses.

Abstract:

A marine vessel for amphibious operations carries a land military vehicle which is secured by a cable and winch arrangement to the deck of the vessel and also positioned by means of a torsion bar. The military vehicle can be moved fore and aft to vary the longitudinal center of gravity of the vessel as a function of water speed so as to a transition the hydrodynamic hump of the vessel to obtain maximum speed with minimum power. The movement of the vehicle is controlled by the vehicle operator who manipulates the recovery winch. The vessel is under the control of the vehicle operator by means of a flexible control cable and a control box which is disposed within the vehicle.

International Classification:

B63B 15/02

US Classification:

Abstract:

Some implementations feature a mast stabilizing device that includes a mast comprising a first portion and a second portion, a sensor coupled to the first portion of the mast, and a pivot structure coupled to the mast. The pivot structure is configured to allow the mast to pivot in the mast stabilizing device. The mast is coupled to the pivot structure so as to pivot along a pivot portion of the mast. The mast stabilizing device also includes a mass coupled to the second portion of the mast. The mass is configured to counteract a force applied to the first portion of the mast. The mast stabilizing device further includes a platform coupled to the pivot structure, the platform configured to operate on a body of water. In some implementations, the pivot structure is a gimbal device.
