总重量可能达到60～70t的空间站将是中国发射入轨的最大航天器,如何避免其遭受微流星体和空间碎片的威胁成为至关重要的问题。本文对我国空间站的空间碎片防护设计过程进行了回顾,包括风险评估、防护结构研制及防护设计等。经防护设计后的空间站PNP值从未加防护的0.0000提高到防护后的0.9397。
The Chinese space station is expected to have a mass between 60-70 tons,and will be the largest spacecraft that China has ever launched into orbit in the history.How to shield the station from risks of micro-meteoroid and space debris is a very important technology.The paper summarizes the development history of the shielding technology for Chinese space station,including the risk assessment,shielding structure development and optimization.The PNP of the Chinese space station rises from 0.000 to 0.9397 after shielding design.
