引言随着我国航天技术的发展,对航天器的寿命提出了越来越高的要求。如何延长航天器在轨寿命已成为目前航天领域的一个研究热点。就目前情况而言,推进剂携带量仍然是决定航天器在轨寿命的最为关键的一个因素。因此,研究航天器推进剂在轨补加技术具有十分重要的现实意义。在轨补加技术是针对在轨运行的高价值航天器推 INTRODUCTION With the development of space technology in our country, more and more high requirements have been put forward on the life of spacecraft. How to extend the lifetime of a spacecraft has become a hot spot in the field of aerospace. In the current situation, propellant loading remains the single most crucial factor in determining the orbital lifetime of spacecraft. Therefore, it is of great significance to study on-orbit addition technology of spacecraft propellant. On-orbit add-on technology is targeted at high-value spacecraft in orbit
