低推力推進式宇宙機による地球捕獲小惑星探査の軌道設計

本研究研究的是一种系统的方法来产生多个月球摆动序列的首次猜测，用于行星际小卫星任务。太阳第三体摄动起着重要的作用，基本上是在月球摆动之间提供自由v。作为第一种方法，提出了经典Tisserand-Pointcar’e图的扩展，其中可以估计飞掠之间太阳摄动的潜在增益。其次，根据Lantoine & McElrath提出的方法，采用延拓法生成月间传输数据库。产生了具有多个转数的新族和靠近振动点轨道的族。可以访问数据库并检索传输，以类似于Lambert问题解决器的方式快速生成序列。给出了两个实际的例子：转移到地月L2点，以及命运号任务启动转移到Phaeton小行星的逃逸策略。

Studied in this research is a systematic approach to generate first guesses of multiple lunar swing-by sequences for interplanetary small satellite missions. The Sun third body perturbation plays an important role essentially providing free v between lunar swing-bys. As a first approach, an extension of the classical Tisserand-Pointcar´e graph is presented, in which the potential gains by solar perturbation between flybys can be estimated. Secondly, following an approach proposed by Lantoine & McElrath, a database of Moon-to-Moon transfers is generated with a continuation method. New families with multiple revolutions and families close to libration point orbits are generated. The database can be accessed and transfers retrieved to quickly generate sequences in similar fashion to a Lambert problem solver. Two practical examples are presented: a transfer to the Earth-Moon L2 point, and an escape strategy for the DESTINY mission to initiate the transfer to asteroid Phaeton.
