摘要
以Starlink为代表的低轨互联网星座是当前航天领域发展的热点,堆叠式多星组合体技术可大幅提高整流罩空间利用率,从而加快低轨星座的建设速度,是未来一箭多星发射技术的重要方向之一.首先,通过分析堆叠式多星组合体技术的需求和意义,总结现有的堆叠式多星组合体的连接形式;然后,通过对比分析指出适合大规模星座建设的连接形式,针对目前应用成熟的堆叠式多星组合体连接方案进行解读,得出该技术的组成原理和技术特点;最后,对堆叠式多星组合体结构设计与连接技术的难点与挑战进行分析并提出展望,为未来堆叠式多星组合体结构设计提供参考.
Abstract
The low orbit internet constellation represented by "Starlink" is a hot topic in the current development of the aerospace field. Multi-satellite stack technology can significantly improve the utilization rate of fairing space,thereby accelerating the construction speed of low orbit constellations,and is one of the important directions of future multi-satellite launching technology. This article analyzes the requirements and significance of multi-satellite stack technology,summarizes the existing connection forms of multi-satellite stack,and then points out the suitable connection forms for large-scale constellation construction through comparative analysis. The mature connection schemes of multi-satellite stack are interpreted,and the composition principle and technical characteristics of this technology are obtained. Finally,the difficulties and challenges in the stucture design and connection technology of multi-satellite stack are analyzed and prospects are proposed,providing reference for future multi-satellite stack structure design.
