| Research Abstract |
This research clarified the characteristics of the deformation and the dynamics of the gossamer multi-body structure, which consists of the gossamer structure, i.e. thin membrane and cable, and its back-up structure such as the spacecraft main body. The research includes the formulation of the theory, numerical simulation, and the ground experiment. The proposed theory and the numerical method were applied to the design and the development of the small solar sail demonstrator “IKAROS” developed by JAXA, and their validity was proved in space by comparing with the flight data of IKAROS. Finally, a new analytical method of gossamer structure was proposed to contribute to put the structure into practical use.
