    摘要: A gas turbine engine includes a compressor section and a turbine section together defining a core air flowpath. Additionally, a rotary component is rotatable with at least a portion of the compressor section and at least a portion of the turbine section. An electric machine is mounted coaxially with the rotary component and positioned at least partially inward of the core air flowpath along a radial direction of the gas turbine engine. A cavity wall defines at least in part a buffer cavity surrounding at least a portion of the electric machine to thermally insulate the electric machine, e.g., from the relatively high temperatures within the core air flowpath.

    摘要: The present disclosure is directed to a gas turbine engine 10 defining a longitudinal direction, a radial direction, and a circumferential direction. The gas turbine engine 10 includes a power turbine 100 including a first turbine rotor assembly 110 interdigitated with a second turbine rotor assembly 120 along the longitudinal direction; a gear assembly 300 coupled to the first turbine rotor assembly 110 and the second turbine rotor assembly 120, wherein the gear assembly 300 includes a first input interface 310 coupled to the first turbine rotor assembly 110, a second input interface 320 coupled to the second turbine rotor assembly 120, and one or more third gears 330 coupled to the first input interface 310 and the second input interface 320 therebetween; and a first output shaft 121 and a second output shaft 122, wherein each of the first output shaft 121 and the second output shaft 122 are configured to couple to an electrical load device.
