The invention provides a conduit trailing edge bionic noise reduction pump-jet propeller and a parametric modeling method.The pump-jet propeller comprises a conduit, a stator, a propeller hub, a rotor and a propeller shaft, the trailing edge of the conduit is provided with a concave-convex structure, the contour line of the concave-convex structure is a sine curve, the concave-convex structure comprises a plurality of concave-convex units which are evenly distributed, and the concave-convex units are connected with the stator. The concave-convex unit is a curve corresponding to the sine curve in one period. According to the technical scheme, the problem that an existing pump propeller is large in noise and poor in concealment performance is solved.

    本发明提供一种导管尾缘仿生降噪的泵喷推进器及参数化建模方法,所述泵喷推进器包括导管、定子、桨毂、转子和桨轴,所述导管的尾缘设置有凹凸结构,所述凹凸结构的轮廓线为正弦曲线,所述凹凸结构包括若干个均匀分布的凹凸单元,所述凹凸单元为所述正弦曲线在一个周期内对应的曲线。本发明的技术方案解决了现有泵推进器的噪声大隐蔽性能较差的问题。
