Abstract:
A fuel system for providing a desired fuel flow to an engine, comprising:a metering assembly for providing a variable portion of metered fuel flow to an associated nozzle system, the variable portion corresponding to a variable demand signal received by the metering assembly; a centrifugal pumping assembly adapted to receive fuel from an associated pumping system, the centrifugal pumping assembly capable of pressurizing and delivering adequate fuel flow to the metering assembly; a throttling valve in fluid communication between the metering assembly and the centrifugal pumping assembly to maintain a constant pressure rise across the metering assembly; an electronic engine control for providing the variable demand signal to the metering assembly; and a fuel temperature probe for providing internal fuel temperature feedback to the electronic engine control to improve the accuracy of metered flow delivered to the associated nozzle system.
