ABSTRACT:
A gas turbine engine control system which receives an engine condition and generates a parameter signal representative of the condition. The control system also receives a temperature signal representative of the engine temperature downstream of the engine combustor. A comparator is used to compare the parameter signal with the temperature signal and a nonrecoverable stall output signal is produced when the temperature signal indicates the temperature is greater than a scheduled value for the given parameter signal. The invention also includes a method for monitoring a gas turbine engine comprising the steps of receiving an engine condition and for generating a parameter signal representative of the condition. A temperature signal is received which is representative of the engine temperature downstream of the engine combustor and then the parameter signal and the temperature signal are received and a nonrecoverable stall output signal is produced when the temperature signal indicates the temperature is greater than a scheduled value for the given parameter signal.
