Abstract: A torque extraction system for a turbine engine includes an electric machine coupled to a shaft of the turbine engine by way of a gearbox disposed between the electric machine and the shaft of the turbine engine, and the electric machine draws torque from the shaft and converts the torque to electrical energy. A power bus is electrically coupled to the electric machine and provides power to the electric machine. A sensor senses vibrational forces acting on a rotor of the turbine engine, and a controller electrically coupled to the electric machine receives signals from the sensor corresponding to the sensed vibrational forces. The controller operates the gearbox disposed between the electric machine and the shaft of the turbine engine to increase the torque that the electric machine draws from the shaft when the vibrational forces sensed by the sensor meet or exceed a predetermined threshold.

Abstract: A cooling system for a turbine engine. The turbine engine includes a compressor, a turbine, and a shaft that drivingly couples the compressor and the turbine. The cooling system includes one or more cavities of the compressor. The cooling system includes a shaft flowpath defined in the shaft. The shaft includes one or more shaft apertures that provide fluid communication between the shaft flowpath and the one or more cavities. Air passes through the one or more shaft apertures and the shaft flowpath during a shutdown of the turbine engine to cool the one or more cavities.
