Abstract
The categories assigned to waveshapes (FIGS. 57-80) of signals derived from electrostatic probes (1, 2, 3, FIG. 1) disposed in the gas stream of a gas turbine engine are combined over a classification record group of about 20 or 30 records (FIG. 81). The possible causation of signals identified by positive and negative threshold crossings is statistically combined by summation across a group of records (FIGS. 85 and 86). The quality values indicative of the likelihood of a waveform correlating to a catagory of engine event are combined across records, category by category, before decisions are made (FIGS. 87 and 88).
