Abstract

A computer program, called ProRAPP, has been developed for the prediction of noise generated by propeller/rotor blades. The acoustic pressure is calculated using a form of Ffowcs Williams-Hawkings equation which is suitable for numerical implementation. For noise predictions, the observer can either move with the propeller/rotor hub or it can be fixed to the ground. Ground reflections are accounted for by superimposing the acoustic pressure for the observer and its image. The numerical results are validated using both wind tunnel and flight test data.
