    • 专利摘要:
    A high-speed ship of the displacement hull type which is adapted to float in a raised position, with the waterline being at a lower position. Greater buoyancy is caused by high-pressure air being held between the bottom plating of the ship and the water flowing under the bottom plating thereby reducing the wave-making drag of the bow and thereby allowing for the ship to have increased capability.

    In addition, the hull can be made with: additional intermediate snow parallel to the side.
    It is advisable that the above-mentioned trimming be equipped with a drive for its reciprocating movement in a vertical plane, and the nose portion of the housing is provided with a guide, front protrusion and a rear groove for moving the above-mentioned trimming along them.
    FIG. 1 shows a schematic view of a catamaran-type vessel described, front view; in fig. 2 is a section A-A in FIG. one; in: FIG. 3 - described vessel with one hull, front view; in fig. 4 is the same, bottom view, in FIG. 5 is a side view on the bow of the described vessel; in fig. b - longitudinal vertical cross section of the bow of the described vessel; in fig. 7 — node I in FIG. 2; in fig. 8 is a vertical section of the lateral skeg; in fig. 9 is a horizontal section of the lateral skeg; in fig. 10 is a vertical longitudinal section of one of the variants of the described vessel; in fig. 11 is a vertical longitudinal section of another embodiment of the ship under navigation.
    The described vessel contains a hull
    1c sheet {| covering, side skids 2, displacement stern and razons of bow 3 and stern 4 parts of the bottom of housing 1. Part 3 is raised relative to part 4 and forms an air cavity B in the air cavity, pneumatically connected to the source 5 of increased pressure . Under part 3 between skegs
    2 a rigid plate 6 is fastened. A pneumatic pressure source 5 is connected with the area behind the plate b from the stern side. The body 1 is made with a ballast tank 7 pneumatically communicated
    with a source of increased pressure. Plate b can be made with channels 8 for communication with a source of increased pressure and with a nasal hollow Hc1 trimming triangular-section 9 along the body 1, equipped with guide-discharge nozzles 10, which are located at the top and bottom of the plate 6.
    Between part 4 and the plate b between the skegs 2, it is advisable to install a flat divider 11.
    Part 3 can be made with an attachment 12 having the ability to reciprocate in a vertical plane. Housing: 1 can be made with additional intermediate skegs 13, parallel to the skegs 2.
    The tool 12 may be provided with a drive 14 for its reciprocating movement in a vertical plane, and a part 3 may be provided with guides 15, a front projection 16 and a rear groove 17 for moving the finishing 12 along them.
    From the pressurized source, the pressurized air can flow through the outlet 18 to the area B through the outlet 19 to the tank 7 and through the nozzles 10 in the plate 6 also to the area c.
    On the ship's station, the supply of pressurized air from pressure source 5 to region B, tank 7 and through channels 8 to plate .6 stops. Water fills the space between skegs 2, and the vessel is in a displacement state (the dashed-dashed waterline in Figure 2).
    At the beginning of the vessel’s movement, the increased air pressure from the pressure source 5 begins to flow through the openings 18, 19 and the nozzles 10, respectively, into the area B and the tank 7. In this case, the plate separates the flow of water into the upper one, moving above the plate 6, and the lower one under this plate. An air cavity is formed between these flows, into which air flows through nozzles 1.0. The air entering the cavity B through the opening 18 displaces the water from the space between the skegs 2. The upper water flow above the plastic 6 prevents air from leaking from the area B forward. The upper and lower water flows adjacent to the plate b restrict the flow from area B to the bottom and to the side of part 4. In addition, by regulating the flow of air into the tank 7, it is possible to change its buoyancy. All this allows to keep the described afloat with a higher waterline (solid line in Fig. 2), which is lowered below part 3. As a result, the characteristic impedance affecting part 3 (and the vessel as a whole) is significantly reduced, which provides the course of this vessel with increased speed.
    The presence of the divider 11 between the skegs 2 allows an increase in the air cavity between the upper and lower water flows over the plate 6.
    The presence of a movable in the vertical direction refining 12 allows the amount of upper water flow above the plate b to be adjusted, which means it prevents the leakage of air from the area B at different speeds of the vessel.
