The invention discloses a rim pump jet propeller. The pump jet propeller comprises a rotating shaft, a shell, a stator and a rotor, and the rotating shaft is of a hollow and trumpet-shaped structure and is movably installed in end covers on the two sides of the shell through a bearing; the rotating shaft comprises a large end part, a small end part and a gradual change part for connecting the large end part and the small end part; a propeller is fixedly mounted in an inner cavity of the large end part, and the rotor is fixedly mounted on an outer ring of the gradual change part; and the stator is fixedly arranged on the shell and corresponds to the rotor. According to the invention, the structural characteristics of a pipeline and the propeller are combined, the Venturi effect is fully utilized, the conventional design is broken through, the layout is reasonable, the contradiction between the high-power stator and rotor and the limited mounting space in the rim pump-jet propeller and the utilization problem of vortex energy in the pipeline are well solved, and the propelling power and the propelling efficiency of the pump jet propeller are greatly improved while the small size of the rim pump jet propeller is guaranteed.

    本发明公开了一种轮缘泵喷推进器,包括有转轴、壳体、定子及转子,所述转轴呈中空、喇叭状结构,通过轴承活动安装在壳体的两侧的端盖中;所述转轴包括有大端部、小端部及连接大端部与小端部的渐变部;所述大端部内腔固定安装有螺旋桨,所述渐变部外环上固定安装有转子;所述定子固定安装在壳体上,与所述转子相对应。本发明结合其管道与螺旋桨的结构特点,并充分利用文丘里效应,突破常规设计,合理布局,极好地解决了轮缘泵喷推进器中大功率的定、转子与有限的安装空间之间的矛盾及管道中涡动能量的利用问题,在保证轮缘泵喷推进器小体积的同时,大大提高了其推进功率及推进效率。
