摘要： A turbine engine includes low and high pressure spools. A high power take-off shaft is coupled to the high spool. An auxiliary component, such as a generator, is configured to be driven by the high power take-off shaft at a first speed. The low spool, in part, drives the auxiliary component, for example, by interconnecting the high power take-off shaft to a lower power take-off shaft through a speed summing gearbox. The gearbox drives the auxiliary component and increases the rotational speed of the auxiliary component from the first speed to the second speed. The low power take-off shaft also drives another generator, in one example. The turbine engine can be started by the low pressure generator, for example, in response to a command from a controller, which transforms the generator into a starter motor.

摘要： An example method of reducing loads on a connection shaft includes disengaging a connection shaft from a motor-generator such that the connection shaft is not rotatably coupled to the motor-generator. The method communicates a fluid away from the motor-generator through a communication path established within the connection shaft. An example turbomachine connection shaft is configured to selectively rotatably couple a turbomachine rotor and a motor-generator. The connection shaft establishes a communication path that selectively vents the motor-generator.

摘要： A variable speed drive (AVSD) includes an input shaft connected to receive a mechanical input from an aircraft engine and an output shaft connected to provide a speed-controlled mechanical output. The AVSD includes a first power path having a fixed gear ratio, a second power path having a variable gear ratio, and a differential coupled to combine power received from the first power path and the second power path for provision to the output shaft. A controller modifies the variable gear ratio of the second power path to regulate the output shaft of the AVSD to a desired speed.
