Summary:PROBLEM TO BE SOLVED: To provide an overspeed preventing system 40 for a gas turbine engine 10 including a rotor. SOLUTION: This overspeed preventing system includes a fuel throttling/shutoff valve 50 coupled to a fuel supply source coupled to the gas turbine engine, a first fuel system interface 56(FSI-1) coupled to the fuel throttling/shutoff valve, a second fuel system interface 58(FSI-2) coupled to the FSI-1, a first control system 102 coupled to the FSI-1 and the FSI-2, including a first driver A(106) and a second driver A(108) and programmed with a first logical algorithm and a second logical algorithm, and a second control system 104 coupled to the FSI-1 and the FSI-2, including a first driver B(110) and a second driver B(112) and programmed with the first logical algorithm and the second logical algorithm.
