Abstract

An engine system is provided for an aircraft having an engine and an engine controller. The engine system includes: an electric machine configured to be in electrical communication with an engine controller to power the engine controller; and a fuel oxygen reduction unit defining a liquid fuel flow path and a blow-off gas flow path and configured to transfer an oxygen content of a fuel flow through the liquid fuel flow path into a blow-off gas flow through the blow-off gas flow path. The fuel oxygen reduction unit is also in electrical communication with the electric motor such that the electric motor at least partially powers the fuel oxygen reduction unit.

Description

technical field [0001] The subject matter generally relates to a fuel oxygen reduction unit for an engine and a method of operating the same. Background technique [0002] A typical aircraft propulsion system includes one or more gas turbine engines. A gas turbine engine generally includes a turbine that includes a compressor section, a combustion section, a turbine section, and an exhaust section in serial flow order. In operation, air is provided to the inlet of the compressor section where one or more axial compressors compress the air step by step until it reaches the combustion section. Fuel is mixed with compressed air and combusted in the combustion section to provide combustion gases. Combustion gases are channeled from the combustion section to the turbine section. The flow of combustion gases through the turbine section drives the turbine section and is then directed through the exhaust section, e.g., to the atmosphere. [0003] Certain operations and systems o...
