Title:
WIG CRAFT COMPRISING MULTIPLE HULLS
Document Type and Number:
WIPO Patent Application WO/2011/111919
Kind Code:
A2
Abstract:
The present invention relates to a WIG craft comprising multiple hulls, which comprises: a plurality of WIG craft vessel bodies comprising multiple hulls; a plurality of propulsion chambers which are provided on the upper parts to the rear of each of the vessel bodies and generate a propulsive force and air-cushioning pressure while off the water; an air-cushion chamber (or chambers) which is (are) positioned on the underside between each of the vessel bodies and guides (guide) propulsion propeller rear pressure while off the water so as to form an air cushion which is used to reduce water resistance; and a duct which forms a link between the propulsion chambers and the air-cushion chamber(s) such that the propeller rear pressure is transmitted to the air-cushion chamber and a cushioning pressure is created. This configuration has the advantageous effect that it solves the prior art problem of providing additional engines and hence allows a reduction in the costs incurred in the manufacture of WIG craft and the weight of WIG craft.
