第一部分介绍北京一号机翼在设计过程中所拟定的两种构造方案——蒙布式的构造方案和全金属式的构造方案。第二部分讨论机翼构造设计中的几个主要问题——设计分离面的选择与构造型式的关系,机翼纵向构件的布置和机翼横向构件的布置等,并利用界限分析来决定机翼翼肋的间隔。界限图上可以反映出机翼各构件布置的相互关系。
In the first part, two kinds of structural schemes proposed by Beijing No.1 wing in the design process are introduced, that is, the structural schemes of the Mongolian type and the all-metal structural schemes. The second part discusses several major issues in the design of wing structure - the relationship between the choice of design separation plane and the type of structure, the arrangement of longitudinal members of the wing and the arrangement of wing transverse members, etc., and uses the bound analysis to determine the wing Rib interval. Boundary map can reflect the layout of the wing of the interrelationships.
