ABSTRACT:
A method of detecting partial flame out in a gas turbine engine combustor is provided which involves the steps of establishing a model for performance of the engine during a particular operating mode of the combustor, wherein the model assumes that all fuel supplied during the combustor operating mode is burned, calculating a value for an engine parameter in the model representative of engine performance, obtaining a sensed value for the engine parameter during operation of the engine at the combustor operating mode, and comparing the calculated value of the engine parameter and the sensed value of the engine parameter, wherein partial flame out of the combustor is detected when the sensed value of the engine parameter differs from the calculated value of the engine parameter by a predetermined amount. This method may be modified in order to take into account performance of the specific engine by establishing a reference value for the engine parameter based on the performance of the engine during the combustor operating mode at total fuel burn and comparing the difference of the sensed and calculated value of the engine parameter to the reference value of the engine parameter before determining whether the difference of the sensed and calculated values of the engine parameter differ by the predetermined amount. Alternatively, the predetermined amount may be modified according to any distinction between performance of the engine and the average performance of a gas turbine engine within the same engine line.
