摘要
箭体结构系统作为运载火箭的重要系统之一,是运载火箭的基础,直接关系着运载火箭的整体性能。针对箭体结构产品尺寸从直径3.35 m到直径5 m的巨大跨越所面临的一系列技术难题,采用创新设计理念建立了一套适用于5 m级大型箭体结构产品设计的理论方法体系,大力推动箭体结构材料体系的更新换代,构建了5 m级大型箭体结构产品体系,实现了5 m级大型箭体结构精细化与多功能一体化设计。
The launch vehicle structure,as one of the important systems of launch vehicle,is the foundation of launch vehicle and directly relates to the overall performance of the launch vehicle.A series of technical problems are faced with the huge leap fromΦ3.35 m toΦ5 m in the product size of the launch vehicle structure.To solve these problems,a set of theoretical and methodological system suitable for the design of theΦ5 m launch vehicle structure products is established by adopting innovative design concept.At the same time,the upgrading of the material system of launch vehicle structure is vigorously promoted.With the implementation of these methods,the product system of theΦ5m launch vehicle structure,and the fine design and multi-function integrated design of theΦ5 m launch vehicle structure are realized.
