Abstract : The report describes a program whos objective was to continue to investigate compressor parameters during pre-stall conditions and to expand the analytical predictability of these parameters. The performance parameters (delta P/P and delta P/q) were analyzed on a steady state basis whereas the high frequency pressure data were analyzed by spectral and broadband noise analysis techniques. The results obtained from the data were limited somewhae due to intermittent failures in the high response sensors but the dalta P/q parameter as analyzed by Wright-Patterson Air Force Base shows significant promise as a stall anticipation signal.
