Abstract: A heat exchanger system includes an additively manufactured inlet header upstream of, and in fluid communication with, the heat exchanger core and an additively manufactured exit header downstream of, and in fluid communication with, the heat exchanger core. A method of manufacturing a header for a ducted heat exchanger system for a gas turbine engine includes additively manufacturing a header with respect to a desired airflow therethrough.

Abstract: A method may comprise preparing a radical-neutralizing composition comprising a cerium compound and a carrier; applying the radical-neutralizing composition to a passageway surface of a lubricant passageway in a lubricant system component; and/or drying the radical-neutralizing composition to form a radical-neutralizing coating on the passageway surface comprising cerium oxide.
