可充气式防护结构具有发射时折叠包装、在轨展开的特性,在同等造价和重量的条件下,与传统的铝结构相比,可以多提供三倍多的空间,节省发射时两倍多的存储体积,是一种能够提高航天器运载效率和长期在轨性能的有效的结构形式,其柔性材料的有效选择可以提高结构的空间环境适应性。介绍了充气式防护结构的材料技术的研究进展,重点分析目前应用的柔性防护材料及充气式防护结构的材料选择。
The inflatable protective structure has the characteristics of foldable package on launch and on-track deployment, providing more than three times more space and saving twice as much emissions as traditional aluminum structures at the same cost and weight The storage volume is an effective structural form that increases the spacecraft’s transport efficiency and long-term on-orbit performance, and the effective selection of flexible materials improves the space-environment adaptability of the structure. The research progress of material technology of inflatable protective structure is introduced, and the material selection of flexible protective material and inflatable protective structure is analyzed emphatically.
