ABSTRACT:
A pair of biased electrostatic probes (27, 28) disposed adjacent respective inlets (32) of the combustor (20) in a gas turbine engine (10) provide an indication of surge (82) if signals, resulting from the outflow of ionic combustion products from the burner can, appear thereon simultaneously, or indications of stall stagnation (97) if signals appear on the two probes out-of-phase with one another, or if either probe senses repetitive signals thereon.
