Then , a new model for the calculation of helicopter rotor aerodynamic noise is established based on the FWH and Kirchhoff equations , which is suitable for the calculations of subsonic and transonic rotor aerodynamic noise .
结合该流场计算方法，本文发展了一个新的基于FWH和Kirchhoff方程的直升机旋翼气动噪声的计算方法和模型。该模型可适合于直升机亚音速至跨音速状态的旋翼气动噪声计算。
