The invention relates to a high-power thruster with a compact structure. The high-power thruster comprises a guide pipe, a first motor, a second motor, a first propeller, a second propeller and a rotating shaft, the first motor is installed at the front end of the guide pipe, and the second motor is installed at the rear end of the guide pipe and sleeved with the rear end of the first motor. The first propeller is fixedly connected with the first motor, and the center of the first propeller fixedly sleeves the front end of the rotating shaft; the second propeller is fixedly connected with the second motor, and the center of the second propeller fixedly sleeves the rear end of the rotating shaft; a first arc surface is arranged on the inner wall of the first propeller. The rear end of the first motor is sleeved with the second motor, so that the size of the propeller is reduced while the same pushing force is ensured; due to the arrangement of the first cambered surface and the second cambered surface, the rotating speed range of the propeller in normal use is increased, so that higher propelling power density is obtained; the problems that a traditional propeller is large in size, large in weight, low in power density and relatively low in propelling efficiency can be solved.

    本发明涉及一种结构紧凑的大功率推进器,包括导管、第一电机、第二电机、第一螺旋桨、第二螺旋桨和转轴;第一电机安装于导管的前端,第二电机安装于导管的后端,第一电机的后端套设第二电机;第一螺旋桨与第一电机固定连接,第一螺旋桨的中心固定套设于转轴的前端;第二螺旋桨与第二电机固定连接,第二螺旋桨的中心固定套设于转轴的后端;第一螺旋桨的内壁设有第一弧面。本发明中第一电机的后端套设第二电机,在确保相同推动力的同时,缩小本方案推进器的体积;而且第一弧面和第二弧面的设置,增加螺旋桨正常使用的转速范围从而获得更高的推进功率密度;可以解决传统推进器存在体积大、重量大、功率密度低和推进效率相对较低的问题。
