    Abstract: A cooling supply package for an electronic component has a supply port communicating with a plurality of outer supply channels, and a return port communicating with a plurality of outer return channels. The outer supply channels and outer return channels communicate with distinct ones of openings in a slot layer and into return and supply slots, respectively. An orifice layer supplies fluid to an electronic component from supply slots and receives return fluid into the return slots after having cooled the electronic component. A cooling supply and electronic combination is also disclosed.

    Abstract: A rotor assembly of an electric machine includes a rotor body and a shaft assembly positioned at a central axis of the rotor assembly, and operably connected thereto. The shaft assembly includes a main rotor shaft operably connected to the rotor body, a center drive shaft located inside of the main rotor shaft, and a hydraulic damper sleeve located radially between the main rotor shaft and the center drive shaft. The hydraulic damper sleeve defines a plurality of cavities between the hydraulic damper sleeve and the center drive shaft. The hydraulic damper sleeve is configured to urge a fluid into and out of the plurality of cavities thereby damping relative circumferential motion between the main rotor shaft and the center drive shaft. A plurality of flow restrictors are configured to easily allow fluid into the plurality of cavities, while restricting flow of fluid out of the plurality of cavities.

    Abstract: An electrical power generation system including a micro-turbine alternator. The micro-turbine alternator including: a combustion chamber, at least one turbine driven by combustion gases from the combustion chamber, a first stage compressor, and a second stage compressor. The first stage compressor and the second stage compressor being operably connected to the combustion chamber to provide a compressed airflow thereto. The micro-turbine alternator including one or more shafts connecting the at least one turbine to the first stage compressor and the second stage compressor such that rotation of the at least one turbine drives rotation of the first stage compressor and second stage compressor. The one or more shafts include a turbine shaft attached to the at least one turbine a compressor shaft attached to the first stage compressor, and a coupling assembly configured to operably connect the turbine shaft to the compressor shaft via a magnetic coupling force.
