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 engages the engine to the dynamoelectric machine through a mechanical differential in a generating mode after the engine reaches self-sustaining speed and combines the output of the engine and the torque converter to regulate the frequency of AC generated by the dynamoelectric machine within a range of frequencies suitable for on-board electrical equipment by dynamically regulating the flow of hydraulic fluid to the torque converter.
