摘要

针对空间对接时某些载荷表面喷涂的涂层受原子氧剥蚀的影响发生反射率退化

从而改变涂层成像特性的问题

本文利用反射率退化一般规律数学模型计算出了在空间经常使用的SR107-ZK白漆两年衰减后的反射率理论值

并根据此理论值为光学系统选择了适当的CCD。按照地球低轨(LEO)飞行两年的太空环境条件

对SR107-ZK白漆试块进行了单一原子氧辐射试验。结果显示

1.810

atom/cm

原子氧通量辐射后的试验数据为0.814

与数学模型模拟计算的数值0.793较为接近

说明了数学模型理论的正确性。对辐射后的试块进行了成像试验

结果表明CCD的合理选择是光学系统对反射率下降试块良好成像的关键

进一步证实了数学模型的可靠性

为今后此类工作提供了重要的依据。

Abstract

As the reflectivity of surface coatings of some loadings will be degenerated in the aircraft docking due to the denudation of atomic oxygen and the imaging characteristics of the coatings will be deteriorative

this paper calculates the reflectivity of SR107-ZK while paint damped for two years by using the universal mathematical model of reflectivity-degeneration. Based on the model

it chooses an appropriated CCD for the optical system. Furthermore

according to the space environmental conditions for flying around the Earth in Low Earth Orbit(LEO) for two years

a single atomic oxygen experiment is performed on a sample painted by SR107-ZK. Experimental results show that the reflectivity data is 0.814 when the sample is radiated by 1.810

atom/cm

which is closed to the theoretical data 0.793 calculated by mathematic model. The result verifies the correctness of the theoretical model. Moreover

an imaging experiment on the tested sample is carried out

and the result indicates that the influence of optical system on the reflectivity degeneration of the sample depends on a reasonable choice of CCD. The results prove the reliability of the proposed model and provide a significant foundation for the intending work.
