摘要
提出了一种实用的等环最级旋翼尾迹生成新法。该方法不仅能够满足识别旋翼桨叶展向多环最峰分布的要求，而且能同时处理正环量峰和负环量峰。与传统的涡格法相比，该法具有快速、简便、可靠及易程序化等优点。
A new efficient method of constant vorticity contours wake modeling for a helicopter rotor is investigated. This method includes three parts: the preprocess of circulation distribution, the determination of generating points of constant vorticity contours and the rotor wake modeling. Not only the multi-peaks of circulation distribution can be identified by using this method, but also the positive and the negative peaks of circulation can be processed at the same time. Numerical simulations show that this new method is very efficient for the helicopter rotor wake modeling, and helpful for determining the induced velocity distributions.
