METHOD FOR MOVING A VESSEL IN WATER AND VESSEL FOR MOVING IN WATER ACCORDING TO SAID METHOD

摘要

The invention relates to shipbuilding and serves to optimize the hydrodynamic characteristics of vessels. The method consists in moving a vessel having a pontoon-type hull with simplified lines, flat inclined portions of the bottom at the fore and aft ends, propellers, a propulsion plant, and an outer skin (5). The latter is moved along the surface of the vessel and of the movable pontoon in the direction of travel of the flows of water along the surface of the vessel and at a speed commensurable to the speed of movement of said flows of water in order to eliminate frictional drag. The ratio of the beam B of the hull to the length L thereof is selected according to the condition: B / L > 0.14. A movable streamlined pontoon (11) at the prow reduces drag. For the free passage of water through the vessel, an inclined shaft (16) is provided behind the pontoon (11), running from the deck to the bottom of the vessel, the walls of said shaft being formed by the inclined transom (7) of the hull and by the aft wall of the pontoon. Air is supplied in the fore and aft ends to reduce wave resistance. On the inside of the outer skin (5) the pressure of the air is constantly maintained, thus preventing water from getting onto the inside surface of the skin. The invention makes it possible to reduce water resistance, thus improving the streamlining of the hull and increasing the rate of sailing of the vessel, as well as to reduce draft, increase the area of the cargo deck and the tonnage of the vessel, and increase the reserve of stability for safe sailing.
