Title:
METHOD FOR REDUCING HYDRODYNAMIC RESISTANCE OF A FLOATING BODY
Document Type and Number:
WIPO Patent Application WO2002040339
Kind Code:
A3
Abstract:
The invention relates to shipbuilding. The inventive method for reducing the hydrodynamic resistance of a floating body consists in supplying gases at a pressure higher than environmental pressure to an environmental space through a section enveloping the side surface of the body and using high-temperature gases at high pressure which are relieved in the form of a jet forward from the nose part of the floating body. The inventive device for carrying out said method comprises a source of gases which have a pressure higher than the environmental pressure. The source is provided with an output section arranged in the nose part of the floating body in such a way that is backward. Said output section envelops the side surface of the body. In addition, the device is provided with an output section arranged in the nose part of the floating body in such a way that is forward. As a result of a gas-vapour medium formed by means of the high-temperature jet, a film boiling on a frontal edge and an artificially formed gas-vapour medium at the side of the floating body, the hydrodynamic resistance is reduced in such a way that the floating body provided with a gas-jet propulsion can develop a high speed (more than 350 miles/hour).
