Title:
HULL CONFIGURATION UTILIZING MULTIPLE EFFECTS
Document Type and Number:
WIPO Patent Application WO2003008262
Kind Code:
A3
Abstract:
A hull configuration for a vessel that utilizes multiple effects to reduce friction between the vessel and the water's surface is provided by the present invention. In various embodiments, a surface effect is employed such that a supporting cushion of air is provided underneath the hull (2) to substantially isolate portions of the hull from coming into contact with the water's surface (100). A blower (374) is used to provide pressurized air to the air cushions. The inlet of the blower (372) is positioned in the direction of the vessel's movement such that a ram air effect decreases the power required by the blower. An amount of thrust is also generated by the forward placement of the blower inlet. The vessel has a superstructure (230) that is shaped to create a low pressure zone above the vessel. This low pressure zone creates a lifting body effect such that the friction between the hull and the water's surface is reduced.
