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: A propulsion system for an aircraft (10) is provided having an aft engine configured to be mounted to the aircraft (10) at an aft end of the aircraft (10). The aft engine includes a fan (304) rotatable about a central axis of the aft engine having a plurality of fan blades (310). The aft engine also includes a nacelle (306) encircling the plurality of fan blades (310) with one or more structural members (308) extending between the nacelle (306) and the mean line (15) of the aircraft (10) at a location forward of the plurality of fan blades (310) when the aft engine is mounted to the aircraft (10). The aft engine may increase a net thrust of the aircraft (10) when mounted to the aircraft (10).

摘要: A turbofan engine 10 is provided including a fan 38 having a plurality of rotatable fan blades 40 and defining a fan pressure ratio during operation of the turbofan engine 10. The turbofan engine 10 also includes a turbomachine 16 operably coupled to the fan 38 for driving the fan 38, the turbomachine 16 including a compressor section, a combustion section 26, and a turbine section in serial flow order and together defining a core air flowpath 37. The turbofan 38 also includes an outer nacelle 50 at least partially surrounding the fan 38 and the turbomachine 16, the outer nacelle 50 defining a bypass passage 56 with the turbomachine 16. A bypass ratio of an amount of airflow through the bypass passage 56 to an amount of airflow through the core air flowpath 37 during operation of the turbofan 38 is less than or equal to about 11 and wherein the fan pressure ratio is less than or equal to about 1.5.

摘要: A system for managing thermal transfer in at least one of an aircraft or a gas turbine engine includes a first engine system 202 utilizing an oil for heat transfer. The oil of the first system has a temperature limit of at least about 500°F. The system additionally includes a fuel system 206 having a deoxygenation unit 212 for deoxygenating fuel in the fuel system 206, as well as a fuel-oil heat exchanger located downstream of the deoxygenation unit 212. The fuel-oil heat exchanger is in thermal communication with the oil in the first engine system 202 and the fuel in the fuel system 206 for transferring heat from the oil in the first engine system 202 to the fuel in the fuel system 206.
