Exploring Large-Scale Additive Manufacturing
Large-Scale Additive Manufacturing (LSAM) can deliver enhanced efficiency, cost-effectiveness and design flexibility for composites cure tooling for Aerospace applications. For a while now NLR operates its own LSAM setup with success and actively participates in various projects dedicated to exploring this process. In a whitepaper NLR addresses the complexities and challenges but it also elaborates on how to make use of the full potential of the LSAM technology.

COMPASS targets 30% waste reduction in aerospace
Co-funded by the European Commission the COMPASS project aims to revolutionise the remanufacturing of end-of-life parts into high quality components. This will lead to significant resource savings and promote a circular economy approach in the aerospace and automotive industries.

R&D case: Liquid hydrogen composite tanks for civil aviation
Hydrogen has been identified as a key priority to achieve the European Green Deal for a sustainable economy. By converting the construction of the hydrogen tank from existing metallic solutions to composites, the liquid hydrogen (LH2) composite tank will achieve weight savings that enable the advancement of liquid hydrogen as a sustainable fuel source for civil aviation. This will lower the carbon footprint of air travel and extend the flight range of aircraft by reducing construction weight and cost.

Innovative solutions from a new technology for sustainable aviation
Royal NLR is aiming to improve two things at the same time: saving weight for aviation structures and speeding up their production processes. NLR is therefore exploring a relatively new technology called large-scale additive manufacturing of fibre-reinforced thermoplastic materials.

Better predictions of metal fatigue in engineering structures
Fatigue of metals can cause premature failure of components and structures that are subject to cyclic loading. To avoid that risk, designers still employ a theory from the 1960s. Royal NLR has now come up with a new equation for calculating the growth rate of cracks under cyclic loading better. The proof of this has recently been published in the journal Engineering Fracture Mechanics.
