The aviation industry must address environmental impact, with hydrogen as a potential sustainable energy carrier. This study investigates an all-composite double-walled vacuum-insulated tank, emphasising challenges in low-temperature storage for viable fuel densities.
The two shells of the insulation need to be interconnected and attached to the surrounding structure. The connectors will introduce loading into the shells, which may originate from the dynamic fuel loading or the thermal expansion mismatch between the two bodies. This study investigates how the point loads of connectors affect the strain state of the composite shells implementing analytical models. The authors anticipate the necessity of striking a balance between the thermodynamics and structures fields. The former aims to minimise the number of connectors for heat transfer reduction, while the latter seeks to increase connector count to maintain load concentrations within acceptable limits.
Studies in literature explore the behaviour of rectangular plates when subjected to a concentrated load on one side and a distributed load on the opposing side. These studies analyse both the strain field and buckling behaviour of the plates. Other works investigate out-of-plane patch loading on composite cylinders. To the authors' knowledge, the studies are limited to a single in-plane load. Reference studies do not consider the interaction of multiple loading points nor account for the hydrogen environment. Our study builds on existing models; alterations will be made to analyse how multiple out-of-plane concentrated edge loads and moments impact the stress and strain state of a composite cylinder subjected to thermo-mechanical loading. The magnitudes of the loads are typical for aviation applications.
This work sustains previous work of the authors, which studies how the inner and outer shell behave when subjected to additional loading, should the hydrogen storage system become part of the primary structure. The study should consider load introduction, a shortcoming this work aims to address.
This study aims to contribute to the design of all-composite vacuum-insulated hydrogen storage vessels by analysing the interaction between the shells. This analysis is crucial for comprehending the interaction between the inner and outer walls and the concentrated loads originating from the connections between said shells. In later stages, the envisioned work shall be used to further increase the integration of the hydrogen storage system. The authors anticipate the evolution of the hydrogen storage vessel into a part of the primary structure, necessitating its capacity to carry additional loads. Investigating the introduction of these loads into the composite shells is a focal point of this study. The overarching goal is to assist the aviation industry in its energy transition by addressing challenges with hydrogen storage.
