| Abstract Scope |
Transportation is responsible for the largest single source of carbon emissions in the UK, making the drive to achieve net zero emissions a key goal to reduce emissions from transportation, including civil aviation. One potential solution is the use of hydrogen as a fuel source. However, this approach presents challenges such as additional storage affecting aerodynamic stability and requires specialized tank geometries. Wire Arc Additive Manufacturing (WAAM) provides design freedom to manufacture complex non-uniform shapes. To achieve cryogenic aerospace applications, aluminium 6xxx/ 2xxx alloys are preferred for aircraft LH2 storage. Nevertheless, welding aluminium can be problematic due to its high thermal/electrical conductivity and affinity to humidity leading to deposition defects. Therefore, this study aims to investigate the feasibility of depositing 2219 series by optimizing process parameters and testing mechanical properties in as-built and heat treated conditions. Moreover, it demonstrates the potential of WAAM for producing tanks suitable for LH2 storage. |
