将太阳帆航天器所涉及的关键技术划分为4个方面:总体设计、轨道和姿态动力学与控制、太阳帆材料及其性能、太阳帆折叠与展开。针对每项关键技术,基于对国外长期研究结果进行分析并阐述主要技术特征,梳理国内相关研究进展,包括笔者与合作者的研究成果,分析存在的主要问题。根据上述分析,指出我国发展太阳帆航天器应该重视的若干问题。 The key technologies involved in solar sail spacecraft are divided into four aspects: the overall design, orbit and attitude dynamics and control, solar sail materials and their performance, solar sail folding and deployment. For each of the key technologies, based on the analysis of long-term foreign research results and the main technical features, combing the domestic research progress, including the author and collaborators research results, analysis of the main problems. Based on the above analysis, it points out some issues that should be paid attention to in our country’s development of solar sail spacecraft.
