摘　　要：半转叶轮仿生推进器是基于半转机构实现韦斯-福(Weis-Fogh)效应的仿生原理构建的新型船舶推进器。文中介绍了推进器的构成及其不同于螺旋桨推进器的推力原理,通过对其叶片进行速度和负载分析,求出在制动这一特殊工况下的制动力、力矩及系统运动方程。A new type of liquid propeller named half-rotating biological propeller is based on principle of Weis-Fogh effect realized by half-rotating mechanism. Composition and principle of propeller are presented in this paper. By analysis of velocity of the vane, force and torque acted by fluid is estimated. Then differential equation of rotation of propeller is set during the brake time.
