摘要
着陆器着陆缓冲系统是嫦娥三号着陆器的重要组成部分,它主要用于保证嫦娥三号着陆器在月面的稳定、安全着陆以及对着陆器的长期有效支撑.本文给出了着陆缓冲系统的主要功能要求、设计时所应考虑的主要因素及最终设计方案,并介绍了仿真试验及地面物理试验的主要验证项目、验证方案及验证结果.嫦娥三号着陆器在月面的稳定、安全着陆表明,着陆缓冲系统设计所考虑的因素全面,设计方案合理,验证方案科学,地面验证充分,产品性能稳定可靠,满足着陆要求.
Landing impact attenuation system is one of the important segments for Chang＇E-3 lander, which ensures Chang＇E-3 lander a stable and reliable landing at touchdown, and a successive support for a long run on the lunar surface. In this paper, the primary requirements, chief factors of the system design and final scheme are introduced. Verification aspects, formulation and results of both experiment and simulation are presented. The successful landing indicated that the attenuation system design and test for Chang＇E-3 lander is rational and reliable. The system met the landing requirements completely.
