摘要
空间碎片与航天器相对撞击速度高达15km/s,8km/s以上毫米级空间碎片地面模拟技术是开展空间碎片防护结构设计的关键技术之一。本文简述了现有的空间碎片地面模拟技术,并分析了运用这些技术开展8km/s以上毫米级球形弹丸发射技术研究的可行性。重点介绍了近年来国际上在8km/s以上毫米级球形弹丸发射实验技术研究中所取得的最新进展,分析了能够取得相关进展的关键技术,探讨了未来技术发展所需要进一步解决的关键问题。
The relative impact velocity between space debris and spacecraft is up to 15km/ s. The ground simulation technology of millimeter-scale space debris above 8km/s is one of the key technologies in the design of space debris shield structure. In this paper, the existing ground-based simulation technologies of space debris are briefly described, and the feasibility of launching millimeter-scale spherical projectiles above 8km/s using these technologies is analyzed. The latest progress in the research of millimeter-scale spherical projectile launching technology above 8km/s in the world in recent years is mainly introduced. The key technologies that can make relevant progress are analyzed, and the key problems that need to be further solved in the future development of the technology are discussed.
