Abstract:
A fuel system for a gas turbine engine includes a first electric motor, a main fuel pump driven by the first electric motor to provide a fuel flow, and an actuator operable by a second electric motor. A first motor controller governs operation of the first electric motor. A second motor controller governs operation of the second electric motor. The second motor controller is operable to control operation of the first electric motor in response the first motor controller being incapable of governing operation of the first electric motor.
