ABSTRACT:
The wave shapes (FIGS. 57-80) of signals derived from electrostatic probes (1, 2, 3) disposed in the gas stream of a gas turbine engine are classified (FIG. 9) into categories relating to engine and other events, and are further correlated or discriminated by other conditions of the engine. Engine acceleration and the sign thereof (FIG. 4) are utilized to correlate and discriminate acceleration and deceleration (FIG. 81). Power lever angle (68, FIG. 1) is utilized (FIG. 4A) to provide an indication of afterburner being lighted, a flameholder probe (27, FIG. 1) becomes biased (82, 83, 85, FIG. 1) to sense when the afterburner is lit, for correlation with afterburner nozzle liner erosion (FIG. 69, FIG. 81). Chopping the fuel to the afterburner is correlated (FIG. 4A, FIG. 81) with signals indicative of the character of the afterburner chop (FIGS. 77-79).
