摘要
嫦娥五号探测器月球无人采样返回任务的复杂性和特殊性对探测器地面试验验证工作提出了很高的要求,试验需求覆盖大系统级、系统级、分系统级、组件级等多个层级,必须针对采样封装、月面起飞、月球轨道交会对接与样品转移、高速再入返回等关键过程进行地面试验验证,试验项目多,试验难度大.在分析了嫦娥五号探测器地面试验验证的特点、各层级试验需求之后,重点介绍了主要大型综合试验的试验系统、试验方法、试验结果等,最后对嫦娥五号探测器地面试验验证技术的创新点进行了梳理,对未来复杂航天器或深空探测器的地面试验和设计验证具有重要的参考价值和指导意义.
The complexity and particularity of Chang’e-5 unmanned lunar sample return missions have high demands for ground-test validation of the Chang’e-5 lunar probe.Test requirements cover multisystem levels,including the large-system,system,subsystem,and component levels.Several difficult ground tests are directed against the key processes,such as sampling and packaging,launching on the moon,rendezvous and docking,and sample transferring in lunar orbit,high-speed reentry.Here,we analyze the features of the ground-test validation for the Chang’e-5 lunar probe and the test requirements of each system level and highlight the testing systems,methods,and results of several large-scale comprehensive tests.Finally,we discuss the innovations of ground-test validation technologies for the Chang’e-5 lunar probe.This article provides important references and guidance for ground tests and design validation for future complex spacecraft or deep space probes.
