摘要
嫦娥五号是我国复杂度最高、技术跨度最大的航天系统工程,本文阐述了嫦娥五号的任务目标和主要技术指标,从系统组成、设计约束和飞行过程3个方面介绍了工程技术方案,重点研究了地外天体采样返回工程系统方案、表取和钻取两种采样模式等7个工程取得的主要技术创新,分析了再入返回飞行试验、月面着陆起飞综合验证试验等8项涉及任务匹配性、协调性和正确性的大型试验,可为后续其他地外天体采样返回任务提供重要参考.
The Chang’e-5 mission is the aerospace project with the highest complexity and largest technical span in China.In this paper,the mission objectives and main technical specifications of the mission are introduced,and the project technical scheme is described in terms of the system composition,design constraints,and flight profile.The focus is on seven aspects of technological innovation,such as a novel scheme of return of samples of extraterrestrial objects and two sampling modes—surface sampling and drilling.Eight large-scale tests involving mission matching,coordination,and correctness were analyzed.The tests included the re-entry flight test and a comprehensive test of lunar surface landing and taking-off.The results can provide an important reference for other extraterrestrial sample return missions.
