宇宙機ミッション軌道への準解析的モデルの応用

在项目的第一年，我们可以密切关注其与研究动力学有关的目的，这将用于涉及螺旋形低推力轨道上不同扰动的DESTINY+使命。首先，开展了一项补充研究，以更新该项目的参考书目。初始开发的动力学模型中提出的问题，使用Equinoctial元素的不同的力量进行了列入不同的力量在动力系统。由于低推力和地球两极的扁平化的力量进行了建模，并包括在我们的调查所采用的物理模型。结果，这些模型的解决方案进行了初步计算，并获得了数值结果。这些结果表明，这些力的实施是成功的，其结果与文献中提供的作品以及高精度轨道传播器进行了验证。由于月球引力引起的第三体摄动的实施正在按原计划进行。这些第一批成果在美国宇航学会第33届AAS/AIAA空间飞行力学会议（德克萨斯州奥斯汀，2023年1月15日至19日）上发表，并以完整文章的形式发表在会议年鉴上。

During the first year of project, we could follow closely its purpose related to the study of dynamics that will be used by DESTINY+ mission involving different perturbations over a spiral low-thrust trajectory. First of all, a complementary study to update the bibliography of the project was developed. The initial　development of dynamical models for different forces presented in the problem using Equinoctial elements was performed with the inclusion of different forces in the dynamical system. The forces due to low-thrust and the flattening at the poles of the Earth were modeled and included in the physical model adopted for the our investigations. As a result, the initial computation of the solutions for these models was performed and numerical results were obtained. These　results　showed that the implementation of the forces was successful, with the results being validated with works available in literature and also with a high precision orbit propagator. The implementation of the third-body perturbation due to Moon's gravitational pull is in progressing accordingly with the original plan. These first outcomes were presented in at the 33rd AAS/AIAA Space Flight Mechanics Meeting of the American Astronautical Society (Austin, Texas, January 15-19 2023) and published in the annals of the conference in a format of complete article.
