Abstract
Structural analysis of a sail solution1 to deorbit satellites is presented in this paper. The deployable drag sail consists of a circular highly flexible frame, sail and housing. The folding process of the highly flexible frame is complex and is only possible to describe analytical2 without a sail attached to the highly flexible frame. FEA has shown a significant difference in the structural behavior with a sail attached to the highly flexible frame and this paper will present these results. Stresses, moment reactions and kinematics are compared in two system (e.g. with and without a drag sail attached to the highly flexible frame). Simulation of folding a drag sail can be challenging due to the instability and slenderness of the structure.
