Abstract
Hydrogen storage is one of the major challenges in the transition to hydrogen-based aviation. To store enough hydrogen with minimum storage weight, carbon fiber reinforced polymer (CFRP) high-pressure tanks in underwing pods are a promising option. Aerodynamic requirements, in addition to structural requirements, lead to advantages of an ellipsoid tank geometry over the classical cylindrical geometry. Ellipsoid hydrogen pressure vessels allow for a better utilization of the design space and therefore a higher hydrogen storage volume. During the design phase, the manufacturing process must be considered to allow for geometric adaptation of the CFRP shell while maintaining the ideal isotensoid stress state in the laminate. Friction during fiber placement allows a deviation from the geodesic filament path in the filament winding process to increase the degree of freedom for the geometry of the vessel. Analytical modelling tools are developed to calculate the required friction coefficient for the isotensoid design of a given ellipsoid geometry. The manufacturing and material parameters are then adjusted and experimentally verified to facilitate this isotensoid design. The analytical methodology is validated by finite element modelling of the winding process and physical manufacturing trials.
