Abstract
A fuel metering system for supplying fuel to a plurality of loads includes a variable displacement piston pump having an adjustable hanger that is movable to a plurality of positions. The variable displacement piston pump is configured to receive a drive torque and, upon receipt of the drive torque, to supply fuel to the plurality of loads at a flow rate dependent on the position of the adjustable hanger. A hanger actuator is coupled to receive hanger position commands and is operable, in response thereto, to move the adjustable hanger to the commanded position. A pump control mechanism is coupled to receive the fuel flow commands supplied by the gas turbine engine controller and is operable, in response thereto, to supply the hanger position commands.
