BWB supplied anodized aluminium components for the H2-Sling, which are used in structural areas as well as in system-relevant assemblies. Anodizing is crucial in aviation because the integral layer protects the aluminium without adding weight, maintains thermal conductivity and at the same time forms a hard, abrasion- and corrosion-resistant surface. The coating remains reliable even under vibrations, temperature changes and mechanical stress.
The aircraft reveal last October represented a significant milestone in the H2 project. The H2-Sling was presented in its entirety from a technical perspective. We are currently working on completing the approval process and have already started the first ground tests,” Fabian Danner, Head of Flight Testing at CELLSIUS Project H2
Our reliable, reproducible production processes ensure that every component has exactly the same layer quality. This consistency is a key factor for safety-critical applications and is important for the scalability of the technology for later series development. With our surface know-how, we are supporting ETH students in driving forward one of the most ambitious projects in sustainable aviation.
"Cellsius' Project Liquid H2 is making significant progress in the development of a liquid hydrogen-powered aircraft that will be the first of its kind to cross the English Channel. The goal of the current project is to develop a demonstrator system that includes a liquid hydrogen tank system, a fuel cell system and the conditioning of the hydrogen," explains Kaspar Oplatka, Cryo Fuel System Engineer, of the Liquid H2 project.
With the consistent further development of the tank system, fuel cell and test infrastructure, the demonstrator system continues to take shape. The careful design of all components - from the insulation to the heating of the hydrogen - shows how complex the path to an airworthy solution is. BWB is supporting the ETH Zurich project team with anodized aluminium parts for selected assemblies and wishes them every success in implementing this pioneering project in sustainable aviation.
