According to the ship resistance reducing system, the high-pressure seawater spraying module is installed below the waterline of the ship, a large number of flat capillary nozzles in the module are used for spraying high-speed water flow to the rear portion of the ship, and a very thin water film flowing backwards at a high speed is formed below the waterline; the seawater resistance borne by the ship during sailing can be greatly reduced by utilizing the water film. The high-pressure seawater spraying module is formed by combining a plurality of modules, is similar to wall bricks, is connected through butt-joint openings and is adhered to the position below a ship waterline. The appearance of the ship does not need to be changed, and the device can be conveniently installed on an existing ship shell. Under the condition that the thrust of the propellers is not changed, the running speed of the ship is related to the backward flowing speed of the water film, when the speeds are equal, the seawater resistance borne by the ship is close to zero, no seawater resistance exists, and the ship can run at a high speed under the action of very small thrust.
本发明设计了一种船只降阻系统,通过在船只吃水线以下安装高压海水喷射模块,利用模块中数量众多的扁平毛细喷口向船只后方喷射高速水流,在吃水线下方形成一层很薄的高速向后流动的水膜,利用这层水膜可大幅降低船只航行时受到的海水阻力。高压海水喷射模块由多个模块组合而成,类似于墙砖通过对接口连接起来,粘贴在船只吃水线下方的位置。不需要改变船只外形,在现有船只外壳上可以很方便加装。在螺旋桨推力不变的情况下,船只行驶速度与水膜向后的流动速度有关,当速度相等时,船只受到的海水阻力接近于零,没有了海水的阻力,船只在很小的推力作用下就可以实现高速行驶。
