摘要
应用CFD技术和气动声学的时域理论,研究直升机旋翼悬停流场及气动噪声。噪声计算以旋翼流动解为基础,采用了气动声学时域理论,文中对该理论进行了推导和说明,并给出了旋翼旋转噪声的预测算例。
By applying the Computational Fluid Dynamics （CFD） technology and the aeroacoustic theory in time domain, the investigation on helicopter rotor noise in hover has been performed in this thesis. Using the flow solution as the input data, the noise of helicopter rotors is calculated by solving the Farassat acoustic formulation based upon the FW-H equation.
