Abstract
A starter/generator system for a gas turbine engine used in aeronautical applications that couples a single dynamoelectric machine to the gas turbine engine through a torque converter in a starting mode, and then disengages the torque converter and engages the engine to the dynamoelectric machine through an adjustable speed transmission in a generating mode after the engine reaches self-sustaining speed, wherein the speed of the adjustable speed transmission is set to match the frequency of AC generated by the dynamoelectric machine with on-board electrical equipment requirements to suit flight conditions.
