Abstract
A direct metering fuel supply system includes a plurality of axial gap motors, a fixed displacement, variable speed positive displacement piston pump, and a gas turbine engine control. Each axial gap motor is configured to be selectively energized and is operable, upon being energized, to supply a drive torque at a drive speed. The fixed displacement, variable speed positive displacement piston pump is coupled to each of the axial gap motors to receive the drive torque selectively supplied therefrom and is operable, upon receipt of the drive torque, to supply fuel at a flow rate dependent on the drive speed. The gas turbine engine control is adapted to receive fuel flow commands and is operable, in response to the fuel flow commands, to energize one of the plurality of axial gap motors.
