Hovercraft

Abstract

The invention relates to a hovercraft which comprises a cockpit, a hull, a buoyancy tank, side walls, aprons, a gas booster, propulsion equipment, fuel equipment and electrical control equipment, wherein the left side and the right side of the hull are respectively provided with a side wall, and the front side and the back side of the hull are respectively provided with an apron; the gas booster comprises a gas boosting cylinder and a gas boosting pipe; a gas inlet is arranged at one end of the gas boosting cylinder, and a gas inlet valve is arranged in the gas inlet; an exhaust outlet is arranged at the other end of the gas boosting cylinder, and an exhaust valve is arranged in the exhaust outlet; an acetylene gas inlet pipe and an igniter are arranged on the outer surface of the gas boosting cylinder; the detonation combustion of the acetylene in the gas boosting cylinder generates high-pressure gas which is conveyed into a gas cushion chamber through the gas boosting pipe; the propulsion equipment comprises a combustion chamber and a water sprayer; the combustion chamber is a cylinder body which is arranged horizontally; a gas inlet is arranged at one end of the combustion chamber, and a gas inlet valve is arranged in the gas inlet; an exhaust outlet is arranged at the other end of the combustion chamber, and an exhaust valve is arranged in the exhaust outlet; an acetylene gas inlet pipe, an igniter and a fuel gas pipe are arranged on the outer surface of the cylinder body; and the detonation combustion of the acetylene in the combustion chamber generates high-pressure fuel gas which is conveyed into the water sprayer through the fuel gas pipe, thereby driving the water in the water sprayer to flow to be spouted at a high speed from a water spout.

Description

technical field [0001] The invention relates to ship technology, in particular to a hovercraft. Background technique [0002] A hovercraft is a ship that uses high-pressure air to form an air cushion between the bottom of the ship and the water surface or the ground, so that all or part of the hull is lifted to achieve high-speed navigation. The air cushion is formed by pressing the air under the bottom of the ship with a high-power compressor, and restricting its escape by air sealing devices such as flexible aprons or rigid side walls around the bottom of the ship. There is an annular nozzle around the bottom of the hovercraft, and the airflow is jetted out at a high speed from the nozzle at an angle. Due to the obstruction of the water surface, the airflow accumulates at the bottom of the boat to form an air cushion, and generates a strong lifting force to lift the boat out of the water. Because the friction between objects and air is much smaller than the friction betwe...

Problems solved by technology

The main engine of a large hovercraft is usually an aero engine, a high-speed diesel engine or a gas turbine. Due to the extremely high requirements on its performance, so far, my country has not yet reached this level.
