Compact Foldable Panels with Hole in the Middle

This paper demonstrates the design and analysis of the compactable foldable structure with a middle hole to promote space and weight efficiency in applications such as solar panels on satellites. The research integrates the middle hole inside the rectangular array so that devices like satellites can be put in the hole. An exhaustive search program is conducted for the array's Hamilton circuits, ensuring the panels can be folded into compact structures without stress. Three models based on the circuit demonstrate that the middle hole allows for efficient folding and deployment, which optimizes storage space. The conclusion highlights the potential of these panels in aerospace applications, suggesting future improvement in the algorithm and experiment validation
