Description
Technical Field
The invention relates to an inflatable partitioned line connection capsule structure, in particular to an integral folding type capsule shell structure with a thickness considered.
Background
The inflatable space capsule is a space capsule which can be inflated and expanded and can be folded and contracted. After the inflatable space capsule enters the track, the inflatable space capsule is inflated and unfolded, so that the inner space is expanded, and the crew can enter the inflatable space capsule through the hatch and carry out related work. And after the task is finished, the structure is folded again and flies back to the earth together with the main structure. The inflatable space capsule is characterized in that: the inflatable module is structurally divided into a structural core and an inflatable shell. In the launch body structure, the shell wall thickness of the inflatable chamber is folded and placed around the structure core by vacuum compression. Upon deployment, the wall thickness of the inflated shell expands around the structural core.
The expansion and contraction of the capsule are determined by the folding and unfolding scheme of the capsule. However, since the external environment in space is complex, the capsule shell needs to resist the impact of micrometalites in space and isolate the deadly cosmic rays from the sun, and the capsule shell has a certain thickness, and the overall folding and unfolding of the thickness of the capsule shell needs to be considered for more accurate calculation. However, many conventional folding and unfolding design schemes cannot consider the overall folding and unfolding of the thickness, and certain errors are generated in the performance estimation of the structure.
Disclosure of Invention
The invention aims to solve the technical problem that the design scheme is designed for the integrally-folded inflatable space capsule partitioning line folding and unfolding considering the thickness, the folding and unfolding are carried out by taking the upper edge and the lower edge of the protective layer partitioning as the center, the integral folding considering the thickness can be considered, the performance of the structure can be estimated more accurately, and the inflatable space capsule partitioning line folding and unfolding method has the advantages of high design reliability, simplicity in design and the like.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
the invention provides an inflatable partitioned line connection capsule shell structure, which is cylindrical and comprises an inner film, an outer film and a protective layer; the protective layers are connected between the inner thin film and the outer thin film in a blocking mode, and all the protective layer blocks are uniformly distributed on the periphery of the space capsule; the protective layer blocks forming the protective layer are cuboids, the protective layer blocks are arranged closely without intervals, each cuboid is provided with an upper inner edge and a lower outer edge, the upper inner edges of the protective layer blocks are connected with the inner thin film, the lower outer edges of the protective layer blocks are connected with the outer thin film, and the connected edges are used as creases for folding and unfolding the space capsule.
The inflatable space capsule shell of the cylinder is divided into a protective layer, an inner film and an outer film which are used for approximately partitioning the structure into cuboid blocks. When the structure is folded, the shell protective layer of the inflatable cabin is compressed by vacuum and is folded and placed around the core of the structure. Each protective layer is connected with the inner film of the inflatable cabin only through the upper inner edge, the lower outer edge is connected with the outer film, and folding and unfolding are carried out by taking the connected edges as centers during folding and unfolding of the space cabin.
The protective layer is made of foam protective materials. In order to protect the internal structure, the foam protective material is arranged in a discontinuous manner, the foam protective material being broken at the fold.
The inflatable blocking line is connected with the capsule structure, and when the capsule is folded and unfolded, the upper edge and the lower edge of each inner membrane, which are connected with the protective layer, are taken as the centers, and the protective layer is mutually coordinated and deformed on the basis of the edges. After the film of the inflatable chamber is folded, the film of the inflatable chamber is contracted in the axial direction, namely, after the inner film of the inflatable chamber is folded, the axial height of the structure of the inflatable chamber is obviously reduced, and the whole structure is folded into a cylinder with smaller height. When the inflatable cabin is unfolded, the film of the inflatable cabin expands, the axial height of the structure of the inflatable cabin is obviously increased, and the whole structure is unfolded into a cylinder with larger height.
Compared with the prior art, the invention has the following beneficial effects:
through blocking the capsule shell protective layer to the upper and lower edge of each protective layer is folded, expanded and contracted as the center, and the overall folding of thickness can be fully considered, and the design reliability is high, and the design is simple, and protective layer thickness prevents the impact of the small object in the space for protection major structure, effectively resists the destruction that various factors of the external environment of space may produce the capsule. When the space capsule is unfolded, the structure performance is stable, and the operation of personnel in the space capsule can be effectively and safely finished. The folding rate of the invention has obvious advantages, the internal space is large when the space capsule is unfolded under the same compression state volume, the damage to the structure is small when the space capsule is unfolded and stored, and the space can be repeatedly used.

Detailed Description
The invention is further described in detail below with reference to the following figures and examples:
as shown in fig. 1, the inflatable blocking line connecting space capsule shell structure of the invention is divided into three layers of an inner film 1, an outer film 2 and a protective layer 3, wherein the protective layer 3 is blocked in an approximately cuboid mode. All the protective layers are uniformly distributed around the space capsule in blocks, and are closely arranged without intervals.
As shown in figure 2, the inflatable cabin protective layer blocks 4 are connected with the inner film 1 through the upper edge joint 5 at the inner edge of the upper part of the block, and are connected with the outer film 2 of the inflatable cabin through the joint 6 at the outer edge of the lower part through glue joint, and similarly, each protective layer block is connected with the inner film edge at the inner edge of the upper part thereof, and is connected with the outer film of the inflatable cabin at the outer edge of the lower part thereof, and each protective layer block forms a whole through the connection mode.
As shown in fig. 3, when the inflatable cabin is folded, the edges of the protective layers connected with the inner film and the outer film are taken as centers, the inner film and the outer film are respectively and independently folded, the protective layer blocks are also folded, in the folding process, the joints of the protective layers and the inner film and the outer film are taken as centers, all the protective layers are turned upwards, the protective layer blocks realize the conversion from the state with larger axial height to the state with larger radial length, the axial height of each block is converted into the radial extension length, and meanwhile, the protective layer blocks are subjected to vacuum compression.
As shown in figure 4, when the capsule is folded, the axial height of the whole structure is obviously reduced, and after the protective layers are turned upwards, the protective layers are stacked together. The height can be reduced in the folding process, and the axial direction can be contracted, so that the space capsule can be accommodated.
