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 the engine controller for powering the engine controller; and a fuel oxygen reduction unit defining a liquid fuel flowpath and a stripping gas flowpath and configured to transfer an oxygen content of a fuel flow through the liquid fuel flowpath to a stripping gas flow through the stripping gas flowpath, the fuel oxygen reduction unit also in electrical communication with the electric machine such that the electric machine powers at least in part the fuel oxygen reduction unit.
Claims20
An engine system for an aircraft having an engine and an engine controller, the engine system comprising:
- an electric machine configured to be in electrical communication with the engine controller for powering the engine controller;
- and
- a fuel oxygen reduction unit defining a liquid fuel flowpath and a stripping gas flowpath and configured to transfer an oxygen content of a fuel flow through the liquid fuel flowpath to a stripping gas flow through the stripping gas flowpath, the fuel oxygen reduction unit also in electrical communication with the electric machine such that the electric machine powers at least in part the fuel oxygen reduction unit.
A method for operating an engine system for an aircraft, the method comprising:
- providing electrical power from an electric machine to an engine controller;
- providing electrical power from the electric machine to a fuel oxygen reduction unit;
- and
- reducing an oxygen content of a fuel flow with the fuel oxygen reduction unit using at least in part the electrical power received from the electric machine.
A method for operating an engine system comprising:
- reducing an oxygen content of a fuel flow to an engine of the engine system using a fuel oxygen reduction unit, wherein reducing the engine content of the fuel flow to the engine of the engine system using the fuel oxygen reduction unit comprises consuming a total amount of power with the fuel oxygen reduction unit in BTU per minute;
- wherein the fuel flow defines a power in BTU per minute, and wherein a ratio of the total amount of power to the power within the fuel flow is between 0.0002:1 and 0.002:1.
