Abstract

A system for detecting a shaft shear comprises a gas turbine engine (102) having a turbine (208), a high inertia rotating component (210) and a driveshaft (212). The turbine (208) drives the high inertia rotating component (210) using the driveshaft (212). A first speed probe (202) is configured to detect a first speed of the driveshaft (212) at a first location associated with the driveshaft (212). A second speed probe (204) is configured to detect a second speed of the driveshaft (212) at a second location associated with the driveshaft (212). Control circuitry (302, 304) is configured to compare the first speed and second speed, determine if the shaft shear has occurred responsive to the comparison and generate a control signal to the gas turbine engine (102) responsive to the determination.
