内容記述 |
Solar sails are an attractive option for a propellant-less propulsion, but only a few missions have been deployed in space so far, such as IKAROS and LightSail 2. To achieve a high characteristic acceleration, a large sail area is required, but it must also be lightweight and robust. Booms can be employed to make the sail stronger, although they are heavier. The solar sail performance can also be impacted by creases. This study looks at the most effective way to fold a long, square solar sail that can be deployed using four booms. Different design ideas were investigated, including the Miura Ori, the Palmer-Shafer flasher, and the IKAROS-inspired parachute folding. The option of partially deploying the sail is taken into account to reduce the sail deformation brought on by SRP while maintaining a high thrust. Other elements, such as the folding height, symmetric deployment and creases, were used to compare the folding processes. Finite Element Analysis (FEA) has been used to compare various folding methods applied to large square sails deployed in space. Finding a sail that is less prone to deformation when partially folded was possible. The Palmer-Shafer flasher fold has been identified as an acceptable folding pattern when comparing features like symmetry, boom deployment, deformation reduction for various support circumstances, and maximum thrust. |
