H2020 NATHENA - New Additive manufacTuring Heat ExchaNger for Aeronautic

New Additive manufacTuring Heat ExchaNger for Aeronautic


Today’s technologies and processes dedicated to the exchangers manufacturing hamper progress on higher performances (mechanical assies of repetitive and regular unitary components like folded sheet metal and/or tubing mostly welded). Traditional manufacturing entails limit for the customization of the inner structure, which have a direct impact on the thermal behavior of the exchanger core. Design and manufacture a complex core structure accordingly and well adapted to the inner thermal phenomenon seems to be a promising way to increase performances.


NATHENA project aims to develop a new kind of heat exchanger for civil aircraft using additive manufacturing. With a strong partnership including the von Karman Insitute for experimental characterization, AddUp Solutions for the development of the additive process, Sogeclair Aerospace for the mechanical conception and Temisth for the heat exchanger design, we ambition to create two optmized heat exchanger by increasing their compactness, their performances and robustness. Additive manufacturing give us the possibility to reduce the number of part to be welded or brazed and give a special global shape of the component to fit to the aircraft as well as possible. Liebherr Aerospace, topic manager of this project, support us for the conception.

This project founded by European Union (Clean Sky 2) at the level of 1.5M€ will last 4 years. It will lead to a proof of concept of a scale 1 heat exchanger tested with laboratory conditions.
