Abstract
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.
Claims17
A turbomachine connection shaft assembly, comprising:
- a connection shaft that is configured to selectively rotatably couple a turbomachine rotor and a motor-generator,
- the connection shaft establishing a communication path that selectively vents a fluid from the motor-generator.
A motor-generator assembly, comprising:
- a motor-generator;
- and
- a connection shaft rotatably coupled to a rotor of a gas turbine and selectively rotatably coupled to the motor-generator, wherein the connection shaft establishes a communication path configured to block fluid flow when the connection shaft is coupled to the motor-generator, and to vent the motor-generator when the connection shaft is decoupled from the motor-generator.
A method of reducing loads on a connection shaft, comprising:
- disengaging a connection shaft from a motor-generator such that the connection shaft is not rotatably coupled to the motor-generator;
- and
- communicating a fluid away from the motor-generator through a communication path established within the connection shaft.
