Patent attributes
A fuel oxygen reduction unit for an aeronautical engine is provided. The fuel oxygen reduction unit includes a stripping gas line that provides a stripping gas flow and a plasma reactor in fluid communication with the stripping gas line. The plasma reactor includes a plasma reactor gas inlet that receives the stripping gas flow from the stripping gas line and a plasma reactor gas outlet that provides the stripping gas flow back to the stripping gas line, the plasma reactor configured to reduce a free oxygen content of the stripping gas flow such that an outlet free oxygen content of the stripping gas flow that exits the plasma reactor gas outlet is lower than an inlet free oxygen content of the stripping gas flow that enters the plasma reactor gas inlet.
