Abstract
An overthrust protection system for a gas turbine in which fuel is supplied at a controlled flow rate to a combustor ( ) of the gas turbine. The overthrust protection system uses a bypass valve ( ) to divert fuel flow away from the combustor ( ). The opening of this valve is controlled by an overthrust controller ( ) to divert fuel flow in response to a detected overthrust condition of the gas turbine. Diverting some of the fuel flow in this manner brings about a reduction in the thrust, allowing the overthrust condition to be controlled without resorting to a complete shut down of the gas turbine.
