The invention discloses a water-air dual-purpose pump spraying propeller, and relates to the technical field of propelling, the water-air dual-purpose pump spraying propeller comprises a shell, a core shaft and a driving device, the shell is cylindrical, the shell is arranged around the core shaft, and a flow channel for medium conveying is formed between the outer surface of the core shaft and the inner side face of the shell; a medium supercharging device is arranged along the flow channel, and the driving device is used for driving the mandrel to rotate. A combustion chamber in an original aero-engine is abandoned, single-runner axial flow supercharging propulsion is adopted, the problem that the combustion chamber part inevitably becomes dead weight during underwater propulsion is solved, and efficient propulsion work of different media in the air part and the underwater part is achieved by adjusting the rotating speed and the like.

    本发明公开了一种水空两用的泵喷推进器,涉及推进技术领域,包括壳体、芯轴和驱动装置,所述壳体呈圆筒状,所述壳体围绕所述芯轴设置,所述芯轴的外表面与所述壳体的内侧面之间形成介质输送的流道;沿所述流道设置有介质增压装置,驱动装置用于驱动芯轴旋转。本申请抛弃原有航空发动机中的燃烧室,采用单流道轴流增压推进,解决在水下推进时燃烧室部分必然成为死重的问题,通过调节转速等方式实现在空中部分和水下部分中不同介质的高效推进工作。
