摘　　要：跳跃式再入返回是深空探测任务的关键环节之一,具有关键技术多、设计约束多、地面验证难等特点。本文按照航天器系统工程的设计思想,针对探月三期“嫦娥五号”(Chang'E-5,CE-5)的再入返回任务,开展了约束条件、再入走廊、气动外形、再入返回弹道设计,明确了各项设计要素之间的关系,提出了“嫦娥五号”返回器系统设计方案,并对再入返回飞行程序和关键任务环节设计进行了说明,经过返回器在轨实际飞行,表明了再入返回任务分析与设计思路正确,为后续的深空再入返回任务奠定了基础。Half-ballistic reentry is one of the key links of deep space exploration mission.It is characterized by many key technologies,many design constrains,and difficulties in experimental verification.According to the idea of System Engineering,aiming at the re-entry and return mission of"Chang'E-5",the design of constraints,reentry corridor,aerodynamic shape and re-entry trajectory is carried out,the relationship between various design elements is clarified,and the design scheme of"Chang'E-5"re-entry system is put forward,and the reentry and return flight procedure and the design of key tasks are also described in this paper.After the actual flight of the reentry vehicle in orbit,it shows that the analysis and design idea of the reentry mission is accurate,which lays the foundation for the subsequent deep space reentry mission.
