摘要
In order to provide a stall prediction method for an axial flow compressor, a high response pressure sensor is provided in a duct wall adjacent to the leading edge of the rotor blade and a rotating stall is predicted by computing autocorrelation of pressure data obtained as a time history data. The initiation of rotating stall is determined when the autocorrelation of the time history data starts dropping rapidly. When it is determined that the rotating stall is imminent, generation of the rotating stall is prevented by taking necessary countermeasures such as to reduce the fuel supply.
