GARDN II Projects (2014-2019)
Additive Manufacturing for Landing Gear
Long-term objective: Apply the laser based powder-bed technology to structural parts to reduce their weight and improve sustainability.
The two main objectives of this project are to:
- Validate the performance of additive manufacturing (AM) process for aerospace non-structural parts;
- Validate the use of standard post-manufacturing processes required for the certification of aerospace parts produced by AM.
To reach TRL 6 within 3 years, the landing gear industry needs to gain confidence in the AM process but also develop the post-manufacturing process.
At the end of the project, the performance of components made by AM will be compared to certifiable machined parts used as reference.
To demonstrate that an additively manufactured landing gear component can be flight-tested, the project team is working on the best design to manufacture 2 prototypes. Manufacturing and quality plans have been drawn up. The team is working towards assessing the commercial performance of the AM landing gear towards the end of 2019. The consortium is trying to find new technologies that allow production quality control and costs reduction. This is due to the fact that current technologies used for AM are pretty expensive and not scalable to production. A flight test is being discussed with Embraer outside of GARDN’s project scope. The project team will keep working on the project after GARDN’s scope.
