| Abstract: | 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. |
