Ducted heat exchanger system for gas turbine engine and method for manufacturing fairing of ducted heat exchanger system for gas turbine engine

摘要

A ducted heat exchanger system for a gas turbine engine includes an additive manufactured heat exchanger core (90) with a contoured external and/or internal geometry. A method of additively manufacturing a heat exchanger for a gas turbine engine includes additively manufacturing a core (90) of a heat exchanger to set a ratio of local surface area to flow area to control a pressure drop per unit length along the core.
