Abstract
The method can include: monitoring a current value of a rate of reduction of torque of the shaft; providing a threshold value for the rate of reduction of torque of the shaft; and generating a signal indicative of the shaft shear event when the current value exceeds the threshold value.
Claims20
A method of detecting a shaft shear event occurring at a shaft of an engine, the method comprising:
- during operation of the engine, at an engine controller:
- monitoring a current value of a rate of reduction of torque of the shaft;
- providing a threshold value for the rate of reduction of torque of the shaft;
- generating a signal indicative of the shaft shear event when the current value exceeds the threshold value.
