Abstract

A fuel system with integrated thrust control malfunction and overspeed protection includes a centrifugal pump (102) for receiving filtered fuel and supplying fuel to a metering and pressure regulating valve, the metering and pressure regulating valve (106) for metering discharge of filtered fuel flow to a gas turbine engine burner, a shut off valve (110) downstream of the metering and pressure regulating valve movable from an open position to either a fully closed position configured for providing rapid shutoff or a partially closed position configured for reduction of fuel flow to the gas turbine engine burner, and a first solenoid (112) and a second solenoid (114) for controlling the shut off valve position.
