单一原子氧辐照对SR107-ZK白漆反射率的影响
Influence of single atomic oxygen radiation on reflectivity of SR107-ZK
摘要
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. 8 X 1022 atom/cm2, 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 experi-merit 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.关键词
