Embodiment 1

[0024] Embodiment one: see Figure 1-Figure 4 , Image 6 , a heavy-duty air-cushion ship in the figure, including a hull. The hull is equipped with an air compressor unit, a high-pressure gas storage tank, and an air supply pipeline, and is also equipped with a power propulsion unit, a transmission mechanism, a propeller unit, and a generator unit. The jet holes evenly distributed on the flat part of the bottom of the ship, each jet hole is connected with the air supply pipeline; Each jet hole is connected respectively, and a check valve is installed on the jet pipeline, and a pressure reducer is installed on the jet pipeline; the jet hole is set at the water diversion part of the bow as the center jet hole, and the diameter of the center jet hole is maximum.

[0025] The upper surface of the bow is provided with a row of jet holes backward from the center jet hole; the two sides of the bow and the bottom surface of the bow are provided with a central jet hole extending from...

Abstract

The invention relates to a method for generating an air cushion by a heavy-duty ship and a heavy-duty hovercraft thereof. The ship contains a hull, wherein an air compressor set, a high-pressure air storage tank and an air supply pipeline are arranged in the hull, the plane part of a hull bottom is evenly distributed with air vents, and each air vent is communicated with the air supply pipeline; the air supply pipeline contains a main pipeline, branch pipelines with a certain number and air vent pipelines with a certain number, wherein the air vent pipelines are respectively communicated with each air vent, check valves are installed on the air vent pipelines, and decompressors are installed on the air vent pipelines; the water diversion position of a fore is provided with an air vent which is a center air vent, and the diameter of the center air vent is largest; and in the method, a high-pressure air layer is generated at the fore by high-pressure gas, an air bubble layer is generated at the hull bottom, the fore, the hull bottom and the water surface are isolated by air, and an air cushion is formed. The frictional resistance of the ship and water is reduced, so that the speed of the heavy-duty ship is higher under the condition of equivalent propulsive force.

Description

1. Technical field [0001] The invention relates to the field of water surface transportation tools, in particular to a method for generating an air cushion in a heavy ship and the heavy air cushion ship. 2. Background technology [0002] At present, all hovercraft in the world are small boats. Its technical content is low, all is to enclose hull with rubber skin, ventilates to the bottom of ship with blower, forms air cushion. Small boats are propelled by high-powered engines, and the speed of the boat is very high. This technique is generally only applicable to the manufacture of small boats. [0003] Chinese invention patent No. is that 02115523.2 proposes a kind of jet air cushion device that can improve the speed of navigation, relates to a kind of inflatable, jet device that is contained around the ship. It installs the main air pipe around the side of the ship. The air inlet of the main air pipe is connected to the air compressor through a pressurized gas storage cy...
