Method of detecting stalls in a gas turbine engine

摘要

A method of detecting stalling in a gas turbine engine (10) by monitoring the intensity of ultraviolet light being sensed in the augmentor (30). The method may be used to confirm a stall when a gas generator burner pressure sensor (72) is operating properly, and as a back-up detection method when the burner pressure sensor (72) fails, or when the burner pressure line to the control system (70) ruptures and fails.
