Classification: CPC F | IPC F

Claim 0:
1. A combined gas turbine engine and fuel supply system comprising:
a gas turbine engine including a combustor and an engine controller, said engine controller taking signals from a plurality of components on the gas turbine engine and identifying a desired flow demand and a desired fuel pressure dependent on conditions at the gas turbine engine;
the engine controller being operable to send a flow demand signal indicative of the desired flow demand and a fuel pressure signal indicative of the desired fuel pressure to a fuel supply system control in a fuel metering unit;
the fuel supply system including a pump connected to a fuel tank, a metering valve downstream of said pump; and
said fuel supply system control separate from the engine controller and programmed to control at least one of said pump and said metering valve, said fuel supply system control operable to take in the flow demand signal and the fuel pressure signal from the engine controller, and identify operation conditions for said at least one of said pump and said metering valve to achieve the desired flow volume and the desired fuel pressure; and
said pump including a motor, and the fuel supply system control further being programmed and operable to control the motor to achieve a desired speed of the pump.
