  • 摘要: “长征五号”(CZ-5)运载火箭是中国全新研制的新一代大型运载火箭,先后圆满完成了中国首次火星探测、探月三期工程“嫦娥五号”探测器发射任务。运载火箭历经30余年关键技术攻关和工程研制,在研制过程中,研发团队攻克了大量的工程技术难题,积累了丰富的大型低温运载火箭研制经验,构建了新一代运载火箭的研制体系,运载火箭的研制能力和研制基础有了质的提升。本文叙述了“长征五号”的研制背景,立足火箭总体技术方案及技术创新,论述了火箭发展思路及模块化构型方案、全箭总体优化设计技术、大直径大集中载荷箭体结构技术等方面内容,探讨了针对深空探测任务的“长征五号”关键技术攻关,具体有深空探测任务轨道设计及优化技术、窄窗口多轨道发射技术。“长征五号”火箭是中国新一代运载火箭标志性重大工程,代表了中国运载火箭技术的最高水平,是中国由航天大国迈向航天强国的重要标志。

     

    Abstract: Long March 5 (LM-5) is a new generation of heavy-lift launch vehicle developed by China. It has successfully completed the first Mars exploration of China and the 3rd phase of China lunar exploration program of Chang’E 5 (CE-5). LM-5 experienced 30 years of key technology research and engineering development. During this period, a lot of engineering technical problems were conquered, rich experience in the development of large cryogenic launch vehicle was accumulated, and the development of the new generation launch vehicle system was constructed. The research capability and foundation of carrier rockets have been greatly improved. This paper describes the development background of LM-5. Based on the overall rocket technical scheme and technical innovation, this paper discusses the development thinking of the rocket, the modular configuration scheme, the overall optimization design technology of the whole rocket and the structure technology of the large diameter and large concentrated load rocket body, and probes into the key technical problems of the LM-5 for the deep space exploration mission, specifically, the orbit design and optimization technology for deep space exploration mission, and narrow window multi-orbit launch technology. LM-5 is a landmark project of China’s new generation of launch vehicle, representing the highest level of launch vehicle technology of China, and is a significant symbol for China’s transformation from a major player in space to major power in space.
