ABSTRACT:
The classification of signals derived from electrostatic probes (1, 2, 3) disposed in the gas stream of a gas turbine engine in accordance with characteristics (FIGS. 14-23) of wave shapes (FIGS. 57-80) of the signals, employs degradation factors (FIG. 25-FIG. 56) which indicate discrepancy between the signal being classified and exemplary signals (FIGS. 57-FIG. 80) corresponding to a plurality of categories. The degradation factor may be fixed (FIG. 34C) or variable (FIG. 24), based on the deviation of the signal characteristic from the corresponding characteristic of the category. The degradation factors are normalized in each of the routines (e.g. 76, FIG. 34D; 19, FIG. 44; 24, FIG. 45B; etc.). Categories are selected in accordance with the least degradation (FIG. 13).
