摘要
针对当前的空间碎片减缓要求,轻小型、模块化、通用化离轨装置的研发成为研究热点。其中薄膜帆离轨装置具有成本低、质量小、发射体积小、面质比大等优点。文章以波兰PW-Sat2立方星离轨帆为例,总结其研制、试验过程,特别是对于帆面和非火工锁紧/释放机构;分析其在轨实验期间的离轨效能和故障模式,并提出可靠性提升方案,以期为我国后续离轨帆产品的研制提供参考。
In response to the current space debris mitigation requirements both at home and abroad,the development of light,small,modular,and generalized deorbiting devices has become a research hotspot.Among them,the deorbiting sail has the advantages of low cost,light weight,small launch volume,and large surfacequality ratio.This paper,by taking the deorbiting sail of the Polish PW-Sat2 CubeSat as an example,introduces its development and test process,as well as a summary of the experiences,with focus on the sail surface and the non-pyrotechnic lock&release mechanism.The deorbiting efficiency and the failure modes during the orbit test are analyzed,and a corresponding reliability improvement program is proposed,to provide some reference for developing subsequent deorbiting sail products in China.
