摘要

The idea has been proposed that the large space antenna utilizes the centrifugal force of spin to deploy and dynamically stabilize the flexible membrane reflector. Since this antenna system has high flexibility, sufficient evaluation of the reflector's shape charac- teristics is indispensable through both experimental and numerical way. To this end we carried out micro-gravity experiment using a small-scale antenna model, and measured the 3-D shape of the model's reflector.
