液体火箭发动机智能脉动装配技术及应用

空间站常态化运行、载人登月工程实施、卫星互联网星座构建等航天工程对运载能力需求迫切。中国科学院沈阳自动化研究所变革传统串行的固定站位装配模式，打造并行制造的智能脉动装配体系。提出导管虚拟装配与定制化设计制造方法，突破大质量异形偏心结构件数字孪生建模与位姿调控技术，研制系列化物理约束下知识 - 数据对抗增强的新型检测装备。构建液体火箭发动机总装脉动生产线，应用于新一代大推力液体火箭发动机，产能提升 10 倍以上。下线的液体火箭发动机已完成 40 余次发射任务，相关成果已推广至航空、航发等行业。
 

Aerospace missions; such as the routine operation of space stations; manned lunar exploration programs; and the construction of satellite internet constellations; have created an urgent demand for enhanced launch capacity. The Shenyang Institute of Automation; Chinese Academy of Sciences; has revolutionized the traditional serial fixed-station assembly model by establishing an intelligent pulsation assembly system that enables parallel manufacturing. The institute proposed a virtual assembly and customized design-manufacturing approach for pipelines; achieved breakthroughs in digital twin modeling and posture regulation technologies for heavy; irregular; and eccentric structural components; and developed a new generation of inspection equipment enhanced through knowledge-data adversarial learning under physical constraints. A pulsation production line for liquid rocket engine final assembly has been established and applied to the new generation of high-thrust liquid rocket engines; increasing production capacity more than tenfold. The assembled engines have successfully completed over 40 launch missions; and the related technologies have been extended to the aviation and aeroengine industries.
