Design of future low Earth orbit small satellites by combining aerodynamic force and solar radiation pressure

我的研究重点是太阳帆在LEO应用中的新用例。太阳帆传统上在地球轨道以外的深空运行。它们在低地球轨道上的使用似乎很有希望，但迄今为止受到的关注有限。在我的JSPS DC 2奖学金期间（2022年4月至9月），我提供了两个主要成果：（i）考虑到该地区太阳帆的独特建模要求，LEO环境的高保真模拟器;（ii）利用该模拟器对低轨太阳帆的基本轨道和姿态动力学特性进行了研究。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LEO太阳帆的新使命概念。多亏了JSPS的资助，我得以在一次国际会议上展示了研究结果，在那里我的研究受到了关注，并对未来的工作提出了有益的建议。此外，我还向国际期刊提交了4篇论文，其中1篇正在付印，2篇在二审稿，1篇在一审稿中。总之，我成功地实现了JSPS PD Fellowship的所有主要研究目标。

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.
