嫦娥五号轨道器构型布局设计与验证

Design and Verification of Configuration for Chang’e-5 Orbiter

嫦娥五号轨道器是中国首次月球无人采样返回探测器的组成部分,具有大承载、轻量化、质心要求零配平、总装实施困难等技术难点。对轨道器的构型布局设计及关键实现环节进行了阐述,包括基本构型设计、构型设计对结构轻量化的贡献、横向质心零配平设计、总装实施创新设计,并以此为基础完成了轨道器的总装设计与系统集成,通过了地面与飞行验证。

The Chang’e-5 orbiter is a part of the first unmanned lunar sampling-return probe in China.It has many technical difficulties,e.g.,large load,light weight,zero balancer,and assembly.In this paper,both the configuration and layout of the orbiter are elaborated,and the key points for implementation are described,including the basic configuration,the contribution of the configuration to light weight,the zero balancer design,and the creative design of assembly.The assembly and integration of the orbiter are accomplished and verified by the ground and flight tests.
