Outline of Final Research Achievements |
In order to enable the space utilization of deployable structures based on three-dimensional twisted origami, research on their fundamental structure and application to spacecraft was conducted. As a result, through analysis and experiments using cube-shaped twisted origami structures, the structural characteristics, deformation mechanisms, and control parameters during deployment were clarified. Additionally, we proposed a structural model for modular structures. Regarding the modular structures, we demonstrated their feasibility in terms of construction and rigidity when applied to magnetic sails.
