Paddle wheel hovercraft

Abstract

A paddle wheel hovercraft Is characterized in that bag finger aprons are arranged on ship boards on the periphery of a hull, two fuel tanks are arranged on the left and right sides in a ship fore room, the fuel tanks are connected with a fuel hydraulic pump station through oil pipes, three main engines are arranged in a ship stern room side by side, middle shafts of main machines on the two sidesare each connected with a hovering fan, the air outlet of each hovering fan is connected with an air pipe, the middle shaft of the middle main engine is connected with a rotating shaft through a steering gear, fixed seats sleeve two ends of the rotating shaft, the fixed seats are fixedly connected into a hull cabin, paddle wheels sleeve the left and right sides of the rotating shaft respectively,and the outer edges of the paddle wheels exceed the bottom of the hull. According to the paddle wheel hovercraft technology, the high-speed paddle wheels are arranged below an air cushion of the hovercraft, the height of the air cushion is adjusted by adjusting the rotating speed of the hovering fans, so that the contact area and pressure of the paddle wheels are controlled, the defect that a flying wheel hovercraft is poor in amphibious performance is overcome, and the defects of an existing hovercraft are also overcome.

Description

【Technical field】 [0001] The invention relates to a ship, in particular to an amphibious paddle wheel hovercraft. 【Background technique】 [0002] At present, Shanghai Yiyi Company is developing a high-speed paddle steamer. The high-speed paddle steamer has high speed, short distance take-off, and no problems such as cavitation, air suction, and entanglement with fishnets in conventional water propellers; the structure is simple, the shape is small, and the cost is low. The maintenance cost is very low, and the maneuverability is good. Due to the use of the flywheel, a huge anti-side drift damping force is generated when the high-speed rotation is performed, so the horizontal drift is small when the high-speed rotation is performed; it can be driven on various surfaces, such as water, shallow water, and land. On, ice (on ice), high speed or medium and low speed driving, good maneuverability on land and ice, etc. But also have certain defect, its amphibious performance is poo...

AI Technical Summary

Problems solved by technology

But there are also certain defects, its amphibious performance is poor, such as when landing, the high-speed flywheel has too high requirements on the ground surface due to the high pressure of the wheels, and the amphibious area is small

[0003] The advantages of the hovercraft are amphibious, high speed, low ground pressure, etc., which can make the global landing beaches rise from 17% in the past to 70%, but the disadvantages of the hovercraft are: large area occupied by the air propeller, large noise, High cost, low specific thrust at low speed, poor concealment and land climbing ability, poor wind resistance, etc. All these shortcomings are caused by the use of aviation air propellers
