A new method has been developed to predict the impulsive noise generated by a transonic rotor blade. The formulation uses a full-potential finite-difference method to obtain the pressure field close to the blade. A kirchhoff integral formulation is then used to extend these finite difference results into the far-field. This Kirchhoff formula, written in a blade-fixed coordinate system, requires initial data across a plane at the sonic radius. This data ...
