ABSTRACT:
The wave shapes of signals derived from electrostatic probes (1, 2, 3) disposed in the gas stream of a gas turbine engine are utilized to correlate the signals (FIGS. 57-59; FIGS. 62-80) with causal engine events, and also to correlate some of such signals (FIGS. 60 and 61) to faults in the diagnostic system, utilizing a special routine (FIG. 44) and also utilizing a routine that can discriminate between fault and engine event (FIG. 45).
