Abstract
A fuel system for providing a desired fuel flow to an engine comprises a metering assembly for providing a variable portion of metered fuel flow to an associated nozzle system. The variable portion corresponds to a variable demand signal received by the metering assembly. A centrifugal pumping assembly is adapted to receive fuel from an associated pumping system. The centrifugal pumping assembly is capable of pressurizing and delivering adequate fuel flow to the metering assembly. A throttling valve is 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 provides the variable demand signal to the metering assembly.
