叶栅型Weis－Fogh振动推进装置

A Cascade Weis Fogh Vibration Propeller

建立了叶栅型Ｗｅｉｓ－ｆｏｇｈ振动推进装置的物理模型和数学模型，应用复变函数理论，求出了流体动力的解析表达式．计算结果表明，流体动力随栅距减少而增加。

This paper gives the mathematical and physical model of a cascade Weis Fogh vibration propeller and obtains the analytical fluid dynamic formula by applying the theory of complex function.The numerical results show that the fluid dynamic forces increase with the distance decrease between the cascades and the average propelling coefficient more than 5 is obtained.
