ABSTRACT:
A fuel system includes a turbine engine, and an electric motor that are independently drivable relative to one another. The electric motor has a speed that is selectively controlled based upon a desired fuel flow. A centrifugal pump is driven by the turbine engine. The centrifugal pump provides a desired fuel pressure for the fuel system. A positive displacement pump is driven by the electric motor The positive displacement pump is in fluid communication with the centrifugal pump, for example in a series arrangement. The positive displacement pump meters a desired volume in response to the speed of the second drive assembly.
