通过总结分析现有国内外空间飞行试验和地面模拟试验原子氧剥蚀数据,采用多项式拟合、自然增长曲线拟合和指数曲线拟合等几种方法,拟合出了能够反映材料厚度损失规律的变化曲线;并结合不同条件下、航天器外表面的原子氧通量计算结果,实现了对航天器外表面不同位置、不同材料的原子氧设计寿命预示,可为航天器的设计和选材提供参考。
By summarizing and analyzing the existing domestic and international space flight tests and ground-based oxygen atom erosion data, several methods such as polynomial fitting, natural growth curve fitting and exponential curve fitting are used to fit the data that can reflect the law of material thickness loss According to the calculation results of atomic oxygen flux on the outer surface of the spacecraft under different conditions, the predictive design life of atomic oxygen at different positions and different materials on the outer surface of the spacecraft is achieved, which can provide reference for the design and material selection of the spacecraft .
