The invention belongs to a propelling system, and particularly relates to a variable water inlet pressurizing water spraying propelling system of an ultra-high-speed boat. A superspeed boat variable water inlet supercharging water jet propulsion system comprises an engine, a jet pump, a steering mechanism and a variable water inlet, the jet pump is composed of a pump body and a water inlet pipe, and the pump body is universal equipment and comprises a main shaft, a turbine, a rectifier and a water jet opening; the main shaft is connected with an engine through a connecting flange. The turbine has the remarkable effects that the water inlet flow is increased, the water pressure on the back surface of the turbine is improved, cavitation bubbles are prevented, the technical problem that the turbine cannot continuously and normally spray water flow due to the cavitation bubble phenomenon at the critical rotating speed or above is solved, the output power of the turbine can still be improved along with the increase of the rotating speed, and the service life of the turbine is prolonged. The problem that an ultra-high-speed boat cannot use a water jet propulsion system is solved.

    本发明属于推进系统,具体涉及一种超高速艇可变进水口增压喷水推进系统。一种超高速艇可变进水口增压喷水推进系统,包括发动机、喷泵、转向机构和可变进水口,所述喷泵由泵体和进水管两部分组成,其中泵体为通用装备,包括主轴、涡轮,整流器和喷水口;主轴通过连接法兰与发动机相连接。本发明的显著效果是:增大了进水流量,提高了涡轮背面的水压,阻止了空泡的产生,解决了涡轮在临界转速以上因“空泡现象”无法继续正常喷出水流的技术问题,使得其输出功率仍能随转速的增加而提高,解决了超高速艇不能使用喷水推进系统的难题。
