A variable catamaran air cushion yacht

Abstract

The invention discloses a variable double-body air cushion yacht. The variable double-body air cushion yacht comprises two piece bodies, a connecting bridge arranged between the two piece bodies, a supercharging chamber arranged in the connecting bridge, an airbag recovery cabin arranged at the peripheral side of the supercharging chamber, and an air cushion cabin arranged below the supercharging chamber, wherein the supercharging chamber consists of multiple supercharging sub-chambers; air ways are formed between the adjacent supercharging sub-chambers; hoisting fans are correspondingly communicated above all the air ways; the supercharging sub-chambers and the adjacent air ways are communicated through air way pipes; airbags are arranged in the airbag recovery cabin, and are communicated with the air ways; meanwhile, multiple air stop devices communicated with the air cushion cabin are arranged at the bottoms of the supercharging sub-chambers; when the hoisting fans are started, air flows to the airbags by the air ways, and flows to the corresponding supercharging sub-chambers by the air way pipes; and when the air in the supercharging sub-chambers bursts through the air stop devices, the air enters the air cushion cabin to form an air cushion. The variable double-body air cushion yacht has the advantage of realizing free conversion between a double-body ship form and a local air cushion double-body ship form or a full cushion hoisting type air cushion double-body ship form through controlling the folding and the unfolding of the air cushion.

Description

technical field [0001] The invention belongs to the technical field of high-performance hybrid ships, and in particular relates to a variable catamaran air cushion yacht. Background technique [0002] Catamaran: It has a large deck area and space, and at the same time can easily obtain a higher speed. Each hull is thinner and longer, thereby reducing the wave-making resistance at high speed, so that it can be more convenient to obtain a higher speed. Speed ​​requirements. Since the width of the catamaran is much larger than that of the monohull, its lateral stability is obviously better than that of the monohull, and it has the ability to withstand relatively large wind and waves; the catamaran not only has good maneuverability, but also has a resistance peak Compared with monohull ships of the same tonnage, the catamaran has a larger overall width, so it often has a larger deck area and cabin volume, especially suitable for loading those ships that are large in size but no...

AI Technical Summary

Problems solved by technology

The function of the air cushion greatly reduces the movement resistance, increases the speed of the ship, and increases the speed of the ship. However, after the compressed air is sprayed out, it escapes to the surroundings, causing quite large waves and splashing a lot of water, which consumes a lot energy

Therefore, although the speed of the ship has increased, the horsepower required is also very large.

At the same time, the hovercraft has poor seakeeping performance, a large stall in sailing in wind and waves, and poor maneuverability
