The goal: enabling lightweight, leak-tight and reliable LHโ tank structures for future aircraft operating at temperatures down to -253โฏยฐC. ย Our R&D work covers key technological components of the process chain โ from surface pre-treatment up to final assembly: โก๏ธ ย Tailored, contact free and gentle surface pre-treatments (e.g. AP-plasma, vacuum UV-light, laser) to ensure reliable adhesion on CFRP โก๏ธ Functional barrier coatings to reduce gas permeability, enhance leak tightness and stabilize vacuum insulation โก๏ธ Automated machining, positioning and adhesive bonding technologies for the assembly of large-scale structures on a 1:1 scale ย The results demonstrate that automated and resource-efficient manufacturing of complex LHโ tank systems is technically feasible. At the same time, they highlight the importance of robust process control, particularly in tolerance management, reproducible joining and long-term material performance under cryogenic conditions. ย Beyond aviation, these developments also offer strong potential for hydrogen infrastructure and other mobility applications. ย A big thank you to our project partners: @airbusgroup (consortium leader), Broetje-Automation GmbH, Deutsches Zentrum fรผr Luft-und Raumfahrt e.V., FIBRE Faserinstitut Bremen e.V., FFT Produktionssysteme, Fraunhofer-Gesellschaft and Technische Universitรคt Dresden as well as to the Bundesministerium fรผr Wirtschaft und Energie for funding and DLR Projekttrรคger for supporting within the LuFo VI-3 program. ย Together, we are shaping the future of hydrogen-powered aviation. โ๏ธ ย ๐ ๐ผ๐ฟ๐ฒ ๐ถ๐ป๐ณ๐ผ๐ฟ๐บ๐ฎ๐๐ถ๐ผ๐ป: ๐https://s.fhg.de/xcg #ifamdrivesinnovation ย Benjamin Diehl, Christoph Brillinger, Leander Brieskorn, Urs Roemer, Bjรถrn Reichel, Dirk Niermann, Christian Bรถhlmann, Simon Kothe, Christopher Dรถlle, Jรถrg Ihde, Lukas Menzel, Dr. Andrea Deissenberger, Thomas Lukaszcyk, Dr.-Ing.
