我国新一代大型运载火箭在新技术应用、运载能力提升等方面均实现了重大跨越。与此同时,其研制难度也显著增加。与在役火箭相比,大型运载火箭具有时序动作多、电磁阀数量多、核心时序涉及环节多、系统间接口复杂等特点。中国航天科技集团公司所属中国运载火箭技术研究院在新一代大型运载火箭初样研制过程中,成功总结出1套适用于设计质量分析的“关 China’s new generation of large launch vehicles has achieved significant leaps in the application of new technologies and carrying capacity. At the same time, the difficulty of its research has also increased significantly. Compared with in-service rockets, the large launch vehicle has many features such as more time-sequence actions, more solenoid valves, more core links and more complex interface between systems. China Aerospace Science and Technology Corporation, a subsidiary of China Academy of Launch Vehicle Technology in the new generation of large launch vehicle prototype development process, the successful conclusion of a set of design quality analysis for the ”off
