摘要
Abstract
In order to meet the requirements for long-term use of Ultra-low orbit(ULO)satel-lites,it is necessary to perform atomic oxygen protection for thermal control materials exposed to high cumulative doses of atomic oxygen or select thermal control materials that are resistant to a-tomic oxygento ensure that the onboard instruments and equipment can maintain a favorable working environment throughout its entire operational lifecycle.The research results on the influ-ence of atomic oxygen on commonly used thermal control materials on domestic and foreign spacecraft are analyzed,and the erosion mechanism and rate of atomic oxygen on various materials are summarized.Based on this,suggestions for thermal control design of ULO satellites at an or-bital altitude of 268km are given,providing reference for the thermal control design of domestic ULO satellites.关键词
