Volume Optimisation of Multi-stable Origami Bellows for Deployable Space Habitats

Abstract Origami bellows are formed by folding flat sheets into closed cylindrical structures along predefined creases. As the unfold, volume of origami structure will change significantly, offering potential for use as inflatable deployable structures. This paper presents a geometric study multi-stable Miura-ori and Kresling bellows, focusing on their application space habitats. Such habitats would be compactly stowed during launch, before expanding once in orbit. The internal ratio between different deployed states is investigated across design space. case study, SpaceX Falcon 9 payload fairing chosen transportation effective calculated to enable comparison with conventional habitat designs. Optimal designs deployment patterned tubular obtained using particle swarm optimisation (PSO) techniques. Configurations significant expansion can found both patterns, patterns achieving higher due additional radial deployment. A multi-objective PSO (MOPSO) adopted identify trade-offs volumetric ratios pattern.
