Abstract: A stator core is provided that can define a plurality of core slots in a surface thereof. The core slots can extend between a first and a second end portion of the stator core. A winding can be housed in the core slots. The winding can define a channel through at least a portion thereof. A cooling system can be operably coupled with the channel and can be configured to move a cooling fluid through the channel. A turbulator can be positioned within the channel. The turbulator can be within a flowpath of the cooling fluid and can be integrally formed with the winding.

Abstract: A turbine engine includes a compressor section, a combustion section, a turbine section, and an exhaust section in serial flow order and together defining a core air flowpath; a fuel delivery system for providing a flow of fuel to the combustion section; and a waste heat recovery system. The waste heat recovery system includes a heat source exchanger in thermal communication with the turbine section, the exhaust section, or both; a heat sink exchanger in thermal communication with the fuel delivery system, the core air flowpath, or both; a thermal transfer bus including a thermal transfer fluid and extending from the heat source exchanger to the heat sink exchanger; and a pump in fluid communication with the thermal transfer bus downstream of the heat source exchanger and upstream of the heat sink exchanger for increasing a temperature and a pressure of the thermal transfer fluid in the thermal transfer bus.
