摘要/Abstract

摘要： 摘要：针对目前星敏感器遮光罩普遍存在的尺寸和质量较大、杂光消除能力受限等问题，从提高吸光涂层吸光率入手，提出碳纳米管遮光罩新概念，研制一套钛合金基底生长碳纳米管涂层的新技术，使得涂层吸光率达到99%以上，并成功制作出可等效替代现有飞行产品遮光罩的碳纳米管遮光罩.通过真空原子氧、紫外辐照、高能粒子辐照、热真空、力学环境等各项空间环境实验，证明其空间环境适用性.与现有星敏感器遮光罩产品的杂光比对试验结果表明，使用碳纳米管遮光罩的星敏感器杂光灰度降低了56%，显示出杂光消除性能的优势.本文创新成果突破了碳纳米管技术在杂光消除领域实际应用的瓶颈技术，对促进星敏感器技术的提高具有重要的工程价值.

Abstract: Abstract： A new conception of CNT (carbon nanometer tube) baffle is presented by increasing the absorptivity of the absorption coat to decrease the baffle outline size and mass, and to enhance the stray light rejection ability. A series of technologies to outgrow CNT coat with absorptivity of 99% more on the Ti alloy base are developed and applied on the new CNT baffle being capable of displacing the current product technology. The space environment applicability of the CNT baffle is demonstrated by a series of ground space environment simulation tests such as atomic oxidation, ultraviolet radiation, highenergy particles radiation, vibrancy mechanics, thermal vacuum, and so on. Comparing the star tracker image values caused by the stray light with the current normal star tracker baffle, the value with the CNT baffle is reduced by 56%, which indicates the advantages of the CNT baffle in stray light rejection. The innovation success shown in this paper breaks through the bottleneck technologies about the practical application of carbon nanometer tube technology in the stray light rejection technical domain, and has important engineering value for the star tracker technology progress.

Key words: Keywords：star tracker, carbon nanometer tube, baffle, stray light rejection
