ABSTRACT:
A gas turbine engine fuel control system has a variable metering device and a throttle valve upstream of the device. The throttle valve is responsive to engine compressor delivery pressure so that fuel pressure at the metering valve inlet is a function of compressor delivery pressure. A pressure drop control device maintains pressure difference across the metering device substantially constant, so that fuel flow to the engine is a function of compressor delivery pressure.
