| Research Abstract |
The present study aimed at developing design-support tools for space gossamer (membrane-cable structure) spacecraft. The tool enables the visualization of design space during the conceptual design phase of space systems. It enables to consider the effect of parameter uncertainties or the coupling with control subsystems. Geometrically nonlinear finite-element methods are mainly used in the tool. This study has successfully applied the tools to the following three practical problems: (1) one-step deployment of a solar sail, (2) shape estimation of a tension-stabilized reflector, and (3) non-synchronous deployment motion of a solar sail.
