METHOD OF REDUCTION OF HYDRODYNAMIC RESISTANCE OF THE VESSEL AND PLANING BOAT

摘要

The invention relates to the building of planing boats. A method of reduction of hydrodynamic resistance of the vessel consists in the creation of flow acting on the hull of the vessel. The density of flow is increased by creating the dense fog in the form of colloidal system "water in air" simultaneously by transverse water and longitudinal air flow, the flow of this fog is divided into three separate flows, two of which are directed under rear sponson of the vessel, and the third -under the rear surface of bottom for creating the aerodynamic lift. The planing boat consists of a hull with bottom, stepped rear end of which is made in the form of Fox sled. In the transom part of the hull an additional sponson is located. Rear sponsons have arched form in the cross section, which smoothly passes into the flat carrying surface. Front sponson is made in the form of a tunnel trimaran. Technical result consists in increase of high-speed qualities of the vessel.
