项目摘要

My research focuses on new use cases of solar sails for LEO applications. Solar sails traditionally operate in deep space, beyond Earth orbit. Their use in LEO appears promising yet has received limited attention until now. During my JSPS DC2 Fellowship (April-September 2022), I delivered two main outputs: (i) a high-fidelity simulator of the LEO environment, considering the unique modelling requirements of solar sails in this region; and (ii) I employed the simulator to shed light on the fundamental orbit and attitude dynamic characteristics of LEO solar sails.Subsequently, during my JSPS PD Fellowship (October 2022) and Assistant Professorship (November 2022 - present), I extended and used the in-house orbit-attitude simulator, combined with knowledge gained on the dynamics via novel analytical tools, to design and evaluate new mission concepts for LEO solar sails. Thanks to financial support from JSPS, I was able to present the results at an international conference, where I received interest in my research and helpful suggestions for future work. In addition, I have submitted four papers on the research conducted during my JSPS DC2 and PD Fellowships to international journals, of which one is now in press, two under second review, and one under first review.In summary, I was able to successfully achieve all of the main research objectives of my JSPS PD Fellowship.

我的研究重点是太阳帆在近地轨道应用的新用例。太阳帆传统上在地球轨道之外的深空运行。它们在近地轨道上的应用似乎很有前景，但迄今为止受到的关注有限。在 JSPS DC2 奖学金期间（2022 年 4 月至 9 月），我交付了两项主要成果：（i）考虑到该地区太阳帆的独特建模要求，低地轨道环境的高保真模拟器； (ii) 我使用模拟器来阐明 LEO 太阳帆的基本轨道和姿态动态特性。随后，在我的 JSPS PD 奖学金（2022 年 10 月）和助理教授（2022 年 11 月至今）期间，我扩展并使用了内部轨道姿态模拟器，结合通过新颖的分析工具获得的动力学知识，设计和评估低地球轨道太阳帆的新任务概念。感谢 JSPS 的资金支持，我能够在一次国际会议上展示我的研究成果，在那里我收到了人们对我的研究的兴趣以及对未来工作的有益建议。此外，我已经向国际期刊提交了四篇关于我在 JSPS DC2 和 PD 奖学金期间进行的研究的论文，其中一篇正在印刷，两篇正在二审，一篇正在一审。总而言之，我能够成功地实现 JSPS PD 奖学金的所有主要研究目标。
