ABSTRACT:
The present invention provides a method of detecting an engine stall based on the intensity of ultraviolet light being sensed in the augmentor. The method is used to confirm a stall when the gas generator burner pressure sensor is operating properly, and as a back-up detection method when the burner pressure sensor fails, or when the burner pressure line to the control system ruptures and fails.
