Abstract
The method can include monitoring a current value of a rate of reduction of rotation speed of the shaft; providing a threshold value of a rate of reduction of rotation speed of the shaft; and generating a signal indicative of the shaft shear event when the current value exceeds threshold value.
Claims13
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 rotation speed of the shaft;
- providing a threshold value of a rate of reduction of rotation speed of the shaft;
- generating a signal indicative of the shaft shear event when the current value exceeds threshold value;
- and
- deactivating the method when a load of the engine is clutched to the shaft.
