Developing a safe, qualified 3D printed aircraft component is a long and arduous process, but additive manufacturing ideas and the added value of 3D printed components for flight make every effort worthwhile. The 3D printing aircraft spoiler hydraulic manifold developed by Airbus, Liebherr, Chemnitz University of Technology and other institutions is undergoing a long process optimization and verification process to achieve hydraulic system performance improvement and aircraft fuel efficiency. Optimized application case.
On March 30, 2017, the A380, which was loaded with the first 3D printed hydraulics, was successfully tested. In this issue, Xiao Bian shared the development process and mass production plan of 3D printing spoiler hydraulic parts through Peter Sander, Vice President of Airbus Emerging Technology and Concepts Department, and shared with the netizens to understand the 3D printing of this application in the aircraft. Hydraulic parts.
Optimize aircraft fuel efficiency
The development of the 3D printed spoiler hydraulic manifold began in 2007, when the Chemnitz University of Technology and the Liebherr Group in Germany launched the aviation hydraulic component additive manufacturing project with the support of the German government fund. In 2010, Airbus joined This project team.
The spoiler hydraulics are a key component of aircraft safety and are designed to control air breaks or spoilers. During the seven years of research and development, the project team has been optimizing the design of the spoiler hydraulics for the additive manufacturing technology of metal 3D printing.
Optimized for design, the final manufacturing solution is to manufacture spoiler hydraulics through selective laser melting (SLM) 3D printing technology and to assemble the 3D printed parts with other hydraulic parts. The 3D printed material is Ti64 titanium. Peter Sander said that the obvious advantage of 3D printing hydraulics is lightweight, which is 35% lighter than the original hydraulics. In terms of performance, 3D printed hydraulics optimize the efficiency of the hydraulic system, producing less heat, reducing noise, and requiring less hydraulic power. The increased efficiency of the hydraulic system will bring additional benefits to the flight, such as reducing air resistance and optimizing the fuel efficiency of the aircraft.
Of course, the team's design innovations for the spoiler hydraulics will not stop there. The next project team will rethink how to design the spoiler hydraulics into a fully integrated additive manufacturing part, further simplifying Complex hydraulic parts manufacturing and assembly processes.
The development and testing process of 3D printing hydraulic parts is a long process. Usually, in order to ensure flight safety, even the hydraulic parts manufactured by traditional manufacturing methods need to pass 12 million test cycles. 3D printing hydraulic parts also need to undergo such a test. After the cycle, the flight test can be carried out.
For this 3D printed spoiler hydraulics, Airbus and Liebherr's ultimate goal is to achieve mass production. Participants in the project The Liebherr Group of Germany is a Tier 1 supplier of Airbus, which delivered 3D printing hydraulics to Airbus at the end of 2016. Liebherr experts have told Airbus that they have more design ideas for aerospace 3D printing hydraulics, and then they will conduct the first round of testing. In the future, they will build an additive manufacturing plant to mass produce these hydraulic components.
Although 3D printing aircraft hydraulics will undergo a long process of development before mass production, Airbus has accumulated practical experience in the production of complex aircraft components using additive manufacturing technology. For example, Airbus subsidiary Premium Aerotec produces double-walled pipe elbows for the A400M military transporter fuel system through selective laser-melting 3D printing technology, as well as 3D printed bionic isolation cabins manufactured by Airbus for the A320 passenger aircraft.
In addition to the active promotion of Airbus at the application level, the development of topology optimization design software and metal 3D printing equipment is also a booster for additive manufacturing technology to enter Airbus production. On the software side, Peter Sander said that Airbus has trained engineers on topology optimization techniques in design software such as Dassault. On the equipment side, Peter Sander believes that the emergence of large-scale metal 3D printing equipment and multi-laser equipment has led to an increase in the production capacity of 3D printing technology. Airbus' 3D printing equipment suppliers EOS, Concept Laser and SLM Solutions have been launched. Multiple laser devices. It is understood that in domestic enterprises, Xi'an Platinum has developed multi-laser metal 3D printing equipment. In 2017, Platinum officially launched the double galvanometer and dual laser equipment BLT-S320, designed to meet the user's production of small batch parts. Efficiency needs.
