The ship drag reduction system comprises an incident flow liquid spraying device, an air spraying device, a high-pressure pump and a control device, the incident flow liquid spraying device is installed at the head of a ship and arranged along the middle longitudinal section of the ship, the high-pressure pump is installed at the bottom of the head of the ship, and the incident flow liquid spraying device is located on one side of the high-pressure pump and connected with the high-pressure pump; the air injection device is arranged on the other opposite side of the high-pressure pump and connected with the high-pressure pump, the air injection device is arranged at the bottom and the two opposite sides of the stem in a U shape, and the control device is installed on the ship and connected with the high-pressure pump in a signal mode. The head incident flow resistance reduction device sprays water at the front edge of the ship in an incident flow mode, so that the high-pressure area of the front edge of the ship can be improved, the viscous pressure resistance of the ship is reduced, the resistance reduction mode can be selected according to the advancing speed of the ship, the spraying speed of the resistance reduction device can be controlled, the defect that a traditional resistance reduction mode is single is overcome, and the resistance reduction efficiency is improved; and the gas-liquid dual-purpose high-pressure pump is adopted to generate high-pressure water flow and bubbles, the installation difficulty of the resistance reduction device is reduced, and installation is convenient.

    本发明公开了一种船舶减阻系统,包括迎流喷液装置、喷气装置、高压泵、控制装置,迎流喷液装置安装于船舶的首部,迎流喷液装置沿船舶的中纵剖面设置,高压泵安装于船首底部,迎流喷液装置位于高压泵一侧并与其连接,喷气装置设置于高压泵的相对另一侧并与其连接,喷气装置在船首底部及相对两侧呈U型设置,控制装置安装于船舶上并与高压泵信号连接。本发明首部的迎流减阻装置在船舶前缘迎流喷水可以改善船舶前缘高压区,降低船舶的粘压阻力,能够根据船舶的行进速度选择减阻方式以及控制减阻装置的喷射速率,消除了传统减阻方式单一性的弊端,提高减阻效率;采用气液两用高压泵生成高压水流和气泡,降低了减阻装置的安装难度,便于安装。
