The research project investigates safety-relevant, additively manufactured (AM) structural components for use in fossil-free aircraft. Using the example of a mounting bracket for a high-pressure hydrogen tank in the research aircraft (FoFlu) of the Technical University of Dresden, the development up to TRL4 and its use in flight will be demonstrated. Increasing air traffic and climate neutrality requirements call for new approaches such as lightweight construction, fossil-free propulsion, diversification of aircraft (GA, UAV, eVTOL) and modern manufacturing technologies. AM processes enable flexible, resource-saving production of highly resilient metal structures – ideal for small series and integral construction methods. The aim is to build a deep understanding of process-related imperfections and develop methods for predicting material and component properties in order to enable targeted post-treatment. AM-compatible design methods and concepts for damage-tolerant design are being developed to enable the certification of safety-relevant components. The classic certification process is being specifically expanded to include AM-specific requirements. The demonstration of a certified AM component in flight shows the potential of the technology for aviation and strengthens the innovative capacity of Saxony's industry.
