DUCTED HEAT EXCHANGER SYSTEM FOR GAS TURBINE ENGINE, AND METHOD OF MANUFACTURING FAIRING OF DUCTED HEAT EXCHANGER SYSTEM FOR GAS TURBINE ENGINE

摘要

PROBLEM TO BE SOLVED: To provide an additively manufactured ducted heat exchanger system with an additively manufactured fairing.SOLUTION: A ducted heat exchanger system for a gas turbine engine includes an additively manufactured heat exchanger core 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 of a heat exchanger to set a ratio of a local surface area to a flow area to control a pressure drop per unit length along the core.SELECTED DRAWING: Figure 6
