Embodiment Construction

[0017] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 , figure 2 , image 3 As shown, an H-shaped boat used in inland rivers and lakes, including the main hull 1 and auxiliary hulls 2 on both sides; The bottom surface of the ship gives the ship a thrust; when the surface paddle 6 pushes the ship, a large amount of air enters the bottom of the ship, and the horizontal plane forms an elevation angle 8 with the hull waterline 7, and as the air continues to enter, the elevation angle continues to increase. The H-shaped wings 3 on both sides of the main hull surround the air at the bottom of the ship to prevent side leakage of air; the wings 4 on the inside of the auxiliary hull and the wings 3 of the main hull divide the space surrounded by the wings 3 of the main hull into three closed spaces open forward. Space; under the action of air lift, three high-pressure air ...

Abstract

The invention discloses an H-shaped drag reduction ship and a working principle and belongs to novel ship body structures. The H-shaped drag reduction ship is formed by a main ship body, an auxiliary ship body, side wings of the main ship body, side wings of the auxiliary ship body, a tail flow plate and a surface paddle and the like. When the ship is anchored on the water surface, a sleigh type bow is inclined upwards, air easily enter the bottom of the boat; when the ship runs, plenty of air enters the bottom surface of the ship, the ship body and the water surface form an elevation angle, H-shaped side wings on two sides of the main ship body enable air to be enclosed at the bottom of the ship, the side wings on the inner side of the auxiliary ship body enable a space enclosed by the side wings of the main ship body to be divided into three sealed spaces open forwards, the tail flow plate is used for controlling the water flow direction, three high-pressure air cushions formed by the three sealed spaces enable the ship body to be gradually separated from the water surface under the lifting effect of air, the wetted area of the ship body is reduced, water resistance to the ship body is reduced, and accordingly the ship speed is increased. The H-shaped drag reduction ship is simple in structure, low in cost and convenient to manufacture and maintain, can remarkably reduce ship resistance and is particularly suitable for offshore use and use for lakes.

Description

technical field [0001] The present invention is a novel hull structure used in inland rivers, lakes and oceans, specifically an H-shaped ship that reduces resistance and increases speed by utilizing the cushioning effect of air. Background technique [0002] With the development of the national economy, people are doing more and more research on ship drag reduction technology. Ship drag reduction technology can significantly reduce fuel consumption and increase ship speed, which has important economic and military value, so it has always been one of the research hotspots in the fields of ship engineering, hydrodynamics and military science and technology at home and abroad. The current ship drag reduction technology mainly uses microbubble drag reduction, air film drag reduction and air curtain drag reduction at the bottom of the ship to increase the speed of the ship, which not only makes the hull structure complex, but also increases the cost, which is not conducive to the...
