초록

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 electri...

청구항

What is claimed is: 1. A starter/generator system for starting a gas turbine engine for aeronautical applications comprising: an alternating current dynamoelectric machine; a torque converter with an input shaft coupled to a drive shaft of the dynamoelectric machine; a first rotation-speed selective coupling with an input shaft coupled to an output shaft of the torque converter and an output shaft coupled to a drive shaft of the engine, wherein the first coupling transfers power from its input shaft to its output shaft so long as the input shaft rotates...
