Abstract: PROBLEM TO BE SOLVED: To improve the reliability of stall detection by detecting the stall of a gas turbine in engine on the basis of the intensity of ultraviolet rays to be detected by an augmenter when a burner pressure sensor fails and/or bursts out. SOLUTION: A gas turbine power unit 10 of aircraft, in an engine control 70, monitors a plurality of engine parameters, calculating the control data, and the variable geometry of a fuel flow and an engine is adjusted, thereby realizing the optimum engine operation. It is equipped with a burner pressure sensor 72 of a gas generator and an ultraviolet detector 74 or a misfire detector as a detecting means of the engine parameters. When the burner pressure detected by the burner pressure sensor 72 exceeds a specified range, an engine warning alarm is emitted. When the burner pressure sensor 72 is out order, the intensity of ultraviolet rays in an augmenter 30 is detected by the ultraviolet detector 74, whereby misfire is detected by an increase of intensity of ultraviolet rays due to the misfire of combustion in the augmenter 30.

Abstract: Normal high load operation automatically varies nozzle area to maintain an optimum engine pressure ratio (EPR). An error signal representing fan damage is established by comparing the actual EPR to the predicted EPR. Compressor stalls are also monitored. In response to these signals a minimum nozzle area is set and modified. Automatic operation to hold EPR and afterburning is inhibited. Further signals representing satisfactory operation may reset the inhibiting action.

Abstract: Nonrecoverable compressor rotating stall in a gas turbine engine is detected virtually at its onset by continuously calculating corrected engine speed and measuring the compressor pressure ratio. Associated with each corrected engine speed is a predetermined, empirically calculated critical pressure ratio. When the actual pressure ratio equals or falls below the critical pressure ratio a nonrecoverable stall has been detected and an output signal is generated which warns the pilot or automatically causes corrective action to be taken.

Abstract: 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.
