Abstract
A starting system and method for a gas turbine engine applies a change in conventional starter generator torque profiles near the conclusion of the start cycle after the engine self sustaining speed and just prior to starter generator cut-out. By decreasing the applied torque to zero prior to transition from a start mode to a generator mode, both the mechanical and electrical transients are greatly decreased.
