The invention belongs to the technical field of aerospace, and particularly discloses a stringer bearing cylinder structure. The inner wall surface of the skin is fixedly mounted on the outer cylinder mounting surface formed by the plurality of outer mounting surfaces, so that the joint of the outer mounting surface of each stringer and the skin is of a plane structure, namely, the stringers and the skin form a plurality of vertically arranged strip-shaped contact surfaces after being mounted, and the phenomenon of local instability can be avoided. Compared with a force bearing cylinder formed by a rod system structure or a skin stringer structure in the conventional technology, the structural efficiency of the force bearing cylinder can be improved.

    本发明属于航空航天技术领域,具体公开了一种桁条承力筒结构。通过将蒙皮的内壁面固定安装于多个外安装面形成的外筒安装面,使得每个桁条的外安装面与蒙皮的连接处为平面结构,也即使得桁条与蒙皮在安装后形成多个竖直布置的条状接触面,可以避免局部失稳的现象发生。相比于常规技术中使用杆系结构或蒙皮桁条结构构成的承力筒,可以提高承力筒的结构效率。
