The invention discloses structural design of an annular propeller pump jet thruster, and belongs to the technical field of underwater propulsion power, the annular propeller pump jet thruster comprises an annular propeller and an annular guide pipe, the annular propeller is sleeved in the annular guide pipe, and the annular propeller and the annular guide pipe are located on the same central axis; the annular propeller comprises a middle shaft, the tail end of the middle shaft is an elliptical cone-shaped tail end, and annular blades distributed along the central axis in an array mode are fixedly arranged on the outer ring of the middle shaft; by arranging the annular propeller pump jet thruster formed by combining the annular propeller and the annular guide pipe, the underwater propelling efficiency can be effectively improved, smaller cavitation can be generated through the curved surface design of the annular propeller pump jet thruster, the better noise reduction stealth effect can be achieved, and the service life of the annular propeller pump jet thruster is prolonged. The propulsion efficiency can be improved through the combined appearance of the underwater vehicle and the annular paddle pump jet propeller.

    本发明公开了一种环形桨泵喷推进器结构设计,属于水下推进动力技术领域,包括环形桨泵喷推进器,所述环形桨泵喷推进器由环形螺旋桨和环形导管组成,环形螺旋桨套设于环形导管中,环形螺旋桨与环形导管处于同一中心轴线;环形螺旋桨包括中轴,中轴的尾端为椭圆锥状尾端,中轴外圈固定设有延中轴线阵列分布的环形叶片;本发明通过设有环形螺旋桨和环形导管组合而成的环形桨泵喷推进器,可有效提升水下推进效率,且其曲面的设计能产生更小的空化,使其能够实现更好的降噪隐身效果,通过水下航行器与环形桨泵喷推进器组合外型可以实现推进效率的提升。
