 note = {It is important for the security of aeroengines to protect the fan and compressor from deterioration of performance and destruction due to rotating stall. An experimental study on the monitoring and prediction of rotating stall affected by inlet-distortion was carried out with an axial-flow compressor. The data on transient phenomena of rotating stall were obtained by the follwoing methods which did not disturb the compressor’s inner flow: the measurements of pressure fluctuation on the compressor caing’s inner wall were made with flush mounted microphones, and the measurement of sound pressure variation was made with a microphone in front of the compressor. The prediction of rotating stall was obtained by the observation of blade stall immediately before rotating stall, especially using the time domain arrangement, not frequency domain, of data from the flush mounted microphones. Both the flush mounted microphones and the microphone in front of the compressor caught rotating stall, independent of the existence of inlet-distortion, but the flush mounted microphone were more effective than the microphone in front of the compressor for the observation of blade stall., 資料番号: NALTR0529000, レポート番号: NAL TR-529},
