Asymmetric deployment dynamics of large membrane

ISAS/JAXA is studying a deployment method using centrifugal force for solar sail mission. The larger sail is required to be deployed statically as for actual spacecraft. We scheduled to deploy the square sail of diameter 20m using a high altitude balloon. In this paper, the mechanisms for static first and second stage deployments are proposed and developed experiment system is introduced. And the operation and results are shown in detail.
