Patent ID: 7581377

Claim:
An emergency fuel shut-off system for a gas turbine engine, comprising: a fuel shut-off device to be actuated for terminating a fuel supply to the engine in response to a mechanical actuation force; an actuator adapted for creating the mechanical actuation force to actuate the fuel shut-off device when a rotor shaft of the engine fails; a fuse apparatus linking the actuator with the fuel shut-off device to transmit the mechanical actuation force from the actuator to the fuel shut-off device, the fuse apparatus being adapted to disable transmission of the mechanical actuation force in order to prevent damage to the fuel shut-off device when the transmitted mechanical actuation force exceeds a pre-selected level; and wherein the fuse apparatus comprises a cable having at least one cross-section thereof sized such that the cable fails when the mechanical actuation force transmitted through the cable exceeds the pre-selected level.
