High speed air cushion vessel hull

Abstract

The invention relates to a high-speed air cushion ship, belonging to the ship technique, wherein said invention comprises a ship hull and mechanical pushing screw mounted at the stern of ship hull; the bottom of hull is flat while the middle part is the main air chamber whose bottom is open; two sides of main air chamber are mounted with stabilize air chambers whose bottoms are open; the hull has air boost device whose high-pressure outlet is through to the main air chamber and the stabilize air chamber; the bottom of ship that at the back of main air chamber is mounted with several diversion grooves concave upwards. The invention has low sailing resistant, simple structure and the application in common or military transportation.

Description

technical field [0001] The invention relates to a hull, in particular to a hull of a high-speed hovercraft. Background technique [0002] Objects moving in water are more resisted by water than in air, because the density of water is about 800 times that of air, so the resistance of objects moving in water is about 800 times that of moving in air. The reason why a ship cannot run fast in the water is the resistance of the water. When the ship runs fast, the resistance of the water also increases sharply. The water resistance hinders the speed of the ship. According to experiments, the speed of the ship has three parts: One is the frictional force, which is produced by the friction between the surface of the hull and the water flow. The larger the area of ​​the hull in contact with water, the greater the frictional resistance. The second is wave-making resistance, which is formed by waves arising from the ship's navigation in the water; the third is eddy current resistance, ...

AI Technical Summary

Problems solved by technology

On this basis, after people's continuous efforts, the hovercraft was invented. The hovercraft set up inflatable cushions on both sides or bottom of the hull, inflates the air cushions during navigation, raises the hull close to the water surface, and uses the wing blades on both sides to stabilize , which greatly reduces the resistance of the water during navigation, and the speed of the ship can be increased to 40-60 knots; but the hovercraft also has fatal shortcomings, because it needs to flush and deflate the air cushion, the structure is complicated, and it is affected by the power of the engine, making the hovercraft The load capacity is very limited. Generally, it can only form a load of several hundred tons. At the same time, its energy consumption is astonishing. It can only be used in special occasions such as short-distance personnel transportation and military transportation.
