摘要：

High-speed rotor noise predictions are performed by means of the ONERA quadrupolar code in the frequency domain. Calculations start from different shock geometries. Results are compared to US Army experiments and discussed. The noise calculation appears to be extremely dependent on the curvature of the shock.
