Ariane 6 is expected to play a key role in Europe's space activities, including scientific exploration, Earth observation, telecommunications, and national security.

June 19, 2023 - Paris and Munich - Oerlikon AM and ArianeGroup signed an order worth up to €900,000 for the production of 3D-printed heat exchanger sets for the new Ariane 6 rocket launcher. The Ariane 6 launcher is a strategic vector for European space access, bringing satellites and high-tech payloads into orbit several times per year. The successful cooperation with ArianeGroup, and the use of additively manufactured components, is another important milestone for Oerlikon as it consolidates its position as a recognized supplier of AM parts to space companies.

Ariane 6 is expected to play a key role in Europe's space activities, including scientific exploration, Earth observation, telecommunications, and national security. It is designed for optimized flexibility and efficiency, to provide a reliable and cost-effective means of launching a wide variety of payloads into space, including satellites. 3D printed aluminum parts from Oerlikon AM will act as heat management devices (heat exchangers) for onboard equipment, supporting the performance and flexibility of the new launcher.

Compact and lightweight
Oerlikon AM worked very closely with the Ariane 6 technical team to ensure the heat management solution meets the most stringent technical specifications. During the development process, the team exploited key advantages of metal 3D printing versus conventional manufacturing, such as increased geometric freedom of design, minimal weight, and rapid lead times. As a result, the heat exchangers' new, compact design fits perfectly into the very limited installation space, capitalizing on the benefits of additive manufacturing.

Designed for series production
After its initial launch, Ariane 6 will take-off several times per year into various orbits, including low Earth orbit, geostationary transfer orbit and sun-synchronous orbit. Thus, the heat exchanger sets were explicitly designed for serial production. Oerlikon AM will support ArianeGroup to meet their production requirements over the coming years, based on the forecasted demand for the rocket. Ariane 6 is projected to emerge as a leading European solution for access to space, with substantial anticipated market demand.

Milestone on the route to class 1 supplier
"Delivering components for Ariane 6 is an important milestone as we consolidate and expand our position as a reliable and innovative partner for serial parts in the space industry. Driving the industrialization of class 2 and 3 space components is the prerequisite of our success. These products are already part of our product portfolio, taking us an important step further on our way to supplying the industry with flight-critical class 1 parts in the very short term," says Hendrik Alfter, Managing Director, Oerlikon AM. "We are confident in our level of expertise and maturity, and further announcements on flight critical parts for launcher applications will follow soon: We have been working in close collaboration with our customers on these applications for a long time now," concludes Hendrik Alfter.

Visit Oerlikon at the Paris Air Show in Hall 2B, Booth E157, and meet the developers of the additively manufactured set of heat exchangers for the Ariane 6 rockets.
