Patent abstract
Systems and methods for detecting a shaft shear event in a turbine engine. An accelerometer coupled to the engine detects an axial acceleration indicative of a shaft shear event in the engine. A control system is configured to, in response to the detected axial acceleration, transmit a signal to initiate a shut down of a fuel system of the engine.
