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

我的研究重点是用于LEO应用的太阳能帆的新用例。传统上，太阳帆在地球轨道以外的深空运行。它们在LEO中的应用似乎很有前景，但到目前为止，人们对此的关注有限。在我的JSPS DC2研究金期间(2022年4月至9月)，我交付了两项主要成果：(1)考虑到该区域太阳帆的独特建模要求，我提供了一个高保真的LEO环境模拟器；(2)我利用该模拟器阐明了LEO太阳帆的基本轨道和姿态动力学特征。随后，在JSPS PD研究金(2022年10月)和助理教授职位(2022年11月至今)期间，我扩展和使用了内部轨道-姿态模拟器，结合通过新颖的分析工具获得的动力学知识，设计和评估了LEO太阳帆的新任务概念。由于JSPS的资金支持，我能够在一次国际会议上展示结果，在会上我对自己的研究感兴趣，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，其中一篇正在出版中，两篇在二次审查中，一篇在第一次审查中。总而言之，我能够成功地实现我的JSPS PD奖学金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.
