Correction and adjusting for the deformation on solar sail

A research on structural deformation of solar sail was presented. Nonlinear deformation of the sail was discussed, which will cause an additional devastating torque because of the shifting of the center of mass (CM).

Summary:A research on structural deformation of solar sail was presented. Nonlinear deformation of the sail was discussed, which will cause an additional devastating torque because of the shifting of the center of mass (CM). Finite-element analysis (FEA) method was carried out. In the computation, a correction was brought in, and a gradually increasing load method was presented. A more accurate membrane deformation result was obtained, and the photons pressure on the membrane was corrected. In purpose to guarantee the control ability in the long mission, a lifting mechanism is developed to adjust the large deformation. The lifting motion and result are verified by Abaqus. The research can be used in the solar sail controlling, where a large deformation may occur and an additional torque will disturb the controlling.
