ABSTRACT:
Turbine aircraft engine starter systems and controllers for use therewith, and methods of starting turbine aircraft engines are described. A starter is operably connected with an aircraft engine and configured to initiate an engine start cycle which includes engine rotation and a fuel ignition point. A power source is connected with the starter and is configured to provide power thereto in accordance with at least first and second settings which apply different magnitudes of voltage to the starter. The first setting initiates the engine start cycle and the second setting accelerates the engine through the start cycle after the fuel ignition point. A controller is operably connected with the starter and the power source and is configured to monitor the engine start cycle and responsive to a controller-determinable time during the engine start cycle changes the first setting to the second setting. In a preferred implementation, the power source comprises a pair of batteries which are permanently connected in series.
