Other Abstract

A three-axis stable, integral tensioned square solar sail deployment mechanism is designed according to the solar sail configuration and its performance requirements. The extension rod synchronization design is performed on the deployment mechanism, and the reasonability of the synchronic design is verified. The influence of the shape of thin-walled booms in resisting tensile and bending deformation was analyzed using finite element method. The results show that lenticular boom has the best comprehensive performance. The static comparative analysis of the Bi-TRAC and the Bi-TRAC welded by two C-shaped rods was carried out. The design of booms to resist blossoming that exist in the process of Bi-TRAC deploying. Comparing three different folding methods of the sail membrane, the relationship between the number of folding and the maximum winding height is given, and the crease index Z is defined to compare the performance of different folding methods in terms of folding numbers and folded volume. The result shows that folding method C is optimal. Finally, SIASAIL-I solar sail is developed, and boom with membrane unfolding test were carried out on the ground. The test process is stable, and there is no blossoming. The booms achieve good synchronism and the tests verify the feasibility of the deployment mechanism.
