摘要
The invention relates to shipbuilding and is directed towards optimizing the hydrodynamic characteristics of future vessels and vessels already in use. The technical result of the proposed method and vessel is a reduction in frictional drag and wave formation and an improvement in the streamlining of the hull of the vessel, leading to a significant increase in the rate of sailing of the vessel in both still and rough water, a reduction in draft, an increase in the area of the cargo deck of the vessel, an increase in tonnage, and an increase in the reserve of stability, thus ensuring operational safety. The method for moving a vessel in water is novel in that the ratio of the beam B of the aforesaid hull to the length L thereof is B / L 0.14; in order to reduce frontal wave resistance, a movable streamlined pontoon (11) is mounted at the fore end, and to allow for the free passage of a volume of water through the vessel, an inclined shaft (16) is provided behind the movable pontoon (11), running from the deck to the bottom of the vessel. When the vessel is in motion, an outer skin (5) moves along the surface of the vessel and of the movable pontoon (11) 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. Furthermore, air is supplied in the fore and aft ends of the moving vessel to reduce the wave resistance of the water, and on the inside of the moving outer skin (5) the pressure of the air is constantly maintained, thus preventing water from getting onto the inside surface of the outer skin (5). The vessel for moving in water according to the above method is novel in that the size of 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) is mounted at the fore end, and an outer skin (5) is mounted so as to be able to move along the surface of the hull and of the movable pontoon (11) 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. The hull of the vessel is provided with additional compartments (12) arranged along the surface of the hull and of the movable pontoon (11); the aforementioned moving outer skin (5) is situated on the outer side of said compartments, and a belt conveyor-type device for moving the outer skin is situated inside each compartment. Furthermore, the compartments (12) are filled with pressurized air, which prevents water from getting onto the inside surface of the outer skin (5). An inclined shaft (16) runs from the deck to the bottom of the vessel, the walls of said shaft being formed by the inclined transom (7) of the water displacing hull and by the aft wall (17) of the movable pontoon (11). The surfaces of the movable streamlined pontoon (11) and the inclined transom (7) are also provided with additional compartments (12) with a moving outer skin (5).
