Description

Moon cabin body structure system combining mechanical expansion and inflation expansion and method
Technical Field
The invention belongs to the field of lunar capsule body structures, and particularly relates to a lunar capsule body structure system combining mechanical expansion and inflation expansion and a method.
Background
The traditional large-scale rigid sealed cabin is heavy in mass, large in size, high in launching cost, difficult to assemble on orbit and limited by the envelope size of a carrier rocket, the design is relatively compact, the effective space in the cabin is narrow, so that a plurality of scientific experiments are difficult to smoothly develop, and the requirements of future deep space exploration and development are more and more difficult to meet. In recent years, with the acceleration of deep space exploration pace, large inflatable deployable structures are becoming the focus of more and more attention. The inflatable and expandable structure is a novel space structure, is made of light flexible composite materials, is in a folded state before launching, is inflated and expanded after being carried to a preset working orbit by a launch vehicle, and therefore a larger effective space or surface area is provided inside or on the surface of the inflatable and expandable structure. Compared with the traditional space rigid deployable structure, the inflatable deployable structure has the advantages of small volume, light weight, low processing and manufacturing cost, easy design and forming, high deployment reliability and the like, and in recent years, due to the development of composite material technology, the deployable flexible protective structure has better protective performance than the traditional rigid shell. The volume of the inflated and expanded working orbit carried by the carrier rocket can reach dozens of times or even dozens of times of the volume of the inflated and expanded working orbit, and the advantage provides an effective solution for constructing a large space structure. Therefore, the development of large-scale inflatable deployable structure research is an ideal way for solving the contradiction between the current lower emission capability and the fast-growing space mission, and has wide application prospect in the future deep space exploration process. Particularly, in future moon base construction and Mars base construction, because the interior of the base needs a large moving space, in order to save construction and launching cost, the inflatable expandable cabin body is an ideal base construction choice.
For technical and material reasons, the following problems still exist with the current inflatable deployable capsule:
(1) For the inflatable structure, the common folding modes are mainly Z-shaped folding and curling folding, but the folding technology applied to the inflatable cabin body in real engineering is Z-shaped folding. Due to the limitation of the folding mode, the cabin body can be unfolded only along the axis and cannot be unfolded along the radial direction. This greatly limits the exertion of the radially deployable advantages of the inflatable structure.
(2) The rigidization of the structure of the inflatable cabin means that the flexible cabin is endowed with certain rigidity in a certain way, so that the flexible cabin can bear self and other additional loads without structural instability. For the inflatable space capsule, the in-plane stress generated on the capsule skin under the action of the internal pressure is enough to enable the capsule to obtain the capacity of resisting the deformation of the external force. In a space environment, however, the airship may encounter a vibrating environment, such as the ignition of an engine. In order to make the whole cabin body stable and not sway relative to other butt-jointed cabin bodies, the cabin body needs to be supplemented with a rigid metal support which can be folded and locked in the cabin body, so that good stability performance is achieved, and the research on the aspect is relatively deficient. The invention innovatively combines the advantages of inflation expansion and mechanical expansion, and is beneficial to the fact that the inflatable building skin system can be lapped on a mechanical expansion structure, so that the stress of the inflatable building skin system is more reasonable.
(3) The inflated deployed tanks are generally designed to be cylindrical or spherical in their deployed shape because the cylindrical or spherical tanks are more uniformly stressed relative to the square or polygonal chambers under the internal pressure of the tank. As mentioned in the point (2), in order to make the whole cabin stable and not sway relative to the other docked cabins, a foldable metal frame is required inside or outside the cabin to ensure the stability and deformation of the whole structure. Therefore, the folding mode of the cabin body depends on the folding mode of the metal frame, and the unfolded shape of the cabin body also depends on the folding mode of the metal frame, and the research or the exploration on the aspect is relatively lacked. The invention provides an achievable folding mode, and the cabin has certain expansibility for the unfolded shape of the cabin.
