Advancing Hydrogen Storage In Aviation: Analysing Load Introduction In All-composite Double-walled Vacuum-insulated Cryo-compressed Vessels
Analysing Load Introduction In All-composite Double-walled Vacuum-insulated Cryo-compressed Vessels
Vacuum-insulated, all-composite hydrogen storage vessels are promising for achieving viable gravimetric and volumetric efficiencies in aviation applications. However, stress concentrations arise due to the connections between the composite shells and to the surrounding structure.
