초록

Improved methods and systems are provided for detecting surge bleed valve faults and analyzing the performance of surge bleed valves in gas turbines. The method includes monitoring the rates of rotation of an engine fan and an engine gas generator in a gas turbine engine. While so doing, a valve status change signal is transmitted to a surge bleed valve in the gas turbine engine. The difference between the two monitored rates of rotation is determined. A surge bleed valve fault signal is generated if the difference between the two monitored rates of rota...
