Deflected and folded inflatable block point connection space capsule shell structure

Abstract

The invention discloses a deflected and folded inflatable block point connection space capsule shell structure which is cylindrical and is composed of an inner thin film, an outer thin film and protective layers. The protective layers are connected between the inner film and the outer film in a blocking mode, and all the protective layer blocks are integrally and evenly arranged on the periphery of the space capsule. The protective layer blocks forming the protective layers are cuboids, different protective layer blocks are closely arranged at intervals, each cuboid is provided with an upper inner edge and a lower outer edge, each edge is provided with two corner points, and the protective layer blocks are connected with the inner film at the corner points of the upper inner edges of the protective layer blocks. One corner point of the outer edge of the lower part of a body diagonal line of the corner point, connected with the inner thin film, of the protective layer block is connected with the outer thin film, and deflection unfolding of the space capsule is carried out by taking the connected corner point as the center. According to the invention, overall thickness folding can be fully considered, micro meteorite impact from the space can be resisted more effectively, lethal cosmic rays from the sun in the space can be isolated, and therefore the safety of the space capsule is guaranteed, and meanwhile a larger internal space can be expanded under the same compression state volume.

Description

technical field [0001] The invention relates to an inflatable block point connection space capsule shell structure, in particular to an integral foldable space capsule shell structure that can consider thickness. Background technique [0002] The inflatable space capsule is a space capsule that can be inflated and expanded, and folded and contracted. Once in orbit, the inflatable capsule is inflated and unfolded, expanding the interior and allowing the crew to enter and work through the hatch. And at the end of the mission, the structure folds again and flies back to Earth with the main structure. The characteristic of the inflatable space capsule is that it is an inflatable module, and its structure can be divided into a structural core and an inflatable shell. In the main launch structure, the shell wall thickness of the inflatable chamber is compressed by vacuum, folded and placed around the core of the structure. When deployed, the wall thickness of the inflatable she...

Problems solved by technology

However, many traditional expansion design schemes cannot consider the overall expansion of the thickness, and there will be certain errors in the performance estimation of the structure.
