A starting system and method for a gas turbine engine includes a controlled starter system and a controlled fuel system. The controlled starter motor is accelerated along an acceleration profile to a dwelling point. Concurrently with the starter motor spinning up the gas turbine engine rotor, the fuel system controller commands the pump motor to drive the fuel pump at a speed which fills the fuel line volumes and establishes adequate pressure for fuel atomization at light off. As the fuel pump motor and starter motor are independently controlled and coor...
1. A starting system for a gas turbine engine comprising:a fuel system controller; a fuel pump for delivering fuel to a gas turbine engine said fuel pump comprising a fixed displacement pump including a rotatable armature and a filter said filter rotatable with the rotatable armature; a starter system controller; a fuel pump motor in communication with said fuel system controller, said fuel pump motor operable to drive said fuel pump in response to said fuel system controller at a pump speed independent of a speed of said gas turbine engine; a starter sy...
