The solar sail is a future propulsion system that uses solar ray radiation pressure as a thrust and it can be used semipermanently. The realization of solar sail needs deployment of extremely large membrane, and spin type solar sails are developed that use centrifugal force for deployment as a candidate. An instrument for deployment of spin type solar sail was developed on the ground and some experiments were carried out using it. In this paper results of the experiments are reported and the experimental and analytical results are investigated.
