[0002]
Civilian large-scale flexible circular or planar structures with a certain thickness mostly adopt the "Z" folding method, and this folding method not only has certain damage to the material but also has a relatively low storage ratio, especially in the aerospace field. The folding of a flexible protective layer with a certain thickness is not practical, so the traditional folding method is difficult to meet the requirements of aerospace applications

The invention provides an inflatable cabin protective layer structure. According to the structure, protective layer modules are arranged in a mutual nested mode after being unfolded by adopting a flake-like configuration, the normal stress of a protective layer after being unfolded can be ensured to be uniform by adopting a staggered weaving belt, and the tangential stress of the protective layerafter being unfolded can be ensured to be uniform and the relative positions of the protection layer modules are ensured to be fixed by adopting a parallel shaping belt. The invention provides a protective layer closing folding scheme which is high in reliability, simple in design, convenient to install, convenient to use, good in processing technology and good in economical efficiency, and particularly relates to a protective layer modularized bionic-flake closing folding structure which is the protective layer configuration structure integrating closing, unfolding and shaping of the protective layer modules into a whole.
Description
technical field [0001] The invention relates to a protective layer structure of an inflatable cabin. Background technique [0002] Civilian large-scale flexible circular or planar structures with a certain thickness mostly use the "Z" folding method, and this folding method not only has certain damage to the material but also has a relatively low storage ratio, especially in the aerospace field. The folding of a flexible protective layer with a certain thickness is not practical, so the traditional folding method is difficult to meet the requirements of aerospace applications. [0003] The protective layer of the inflatable cabin in the aerospace field is a multi-layer flexible film material, which has certain compressibility. The thickness of the entire protective layer material can reach 20-500 cm, and it is required to have a high storage ratio. Based on the requirement of high storage ratio for the folding and folding of the protective layer of the aerospace inflatable ...
