The invention discloses a high-speed boat surface paddle propelling system and a high-speed boat sliding-up control method.The propelling system comprises a stern shaft tube, a shaft system arranged in the stern shaft tube and a surface paddle installed on the shaft system, the stern shaft tube is provided with an air injection device, the air injection device is located in front of the surface paddle, and the surface paddle is installed on the shaft system. The air injection device is connected with a high-pressure air source, and an air injection opening of the air injection device faces the surface paddle. In the sliding starting process of the surface propeller, the surface propeller is completely located below the free liquid level, the high-pressure gas source supplies high-pressure gas to the gas spraying device, the gas is sprayed towards the propeller hub and the blade root of the surface propeller through the gas spraying opening, the propeller hub and the blade root are full of gas, and the overall torque of the surface propeller can be effectively reduced in the gas-liquid mixed flow environment at the low rotating speed; therefore, the power required by rotation of the surface propeller is reduced to be lower than the external characteristic power of the diesel engine at a low speed, the problem that the high-speed boat is difficult to slide at a low speed is solved, and the efficiency of the surface propeller during low-speed operation can be improved.
本发明公开了一种高速艇表面桨推进系统及高速艇起滑控制方法,推进系统包括:艉轴管、设于所述艉轴管内的轴系和安装于所述轴系上的表面桨,所述艉轴管安装有喷气装置,所述喷气装置位于所述表面桨的前方,所述喷气装置连接高压气源,所述喷气装置的喷气口朝向所述表面桨。表面桨起滑过程中,表面桨完全位于自由液面以下,高压气源供给喷气装置供给高压气体,并通过喷气口朝向表面桨的桨毂及叶根附近喷射气体,使得桨毂及叶根处充满气体处于气液混合流环境下,低转速时,可有效减小表面桨整体扭矩,进而减小表面桨旋转所需功率,使其低于低速时柴油机外特性功率,解决高速艇低速起滑困难的问题,同时可提高表面桨低速运行时效率。
