The second rigid bearing end face 3 is supported at the other end, i.e. the lower end in fig. 1, of the rigid bearing structure 1. The upper end of the flexible pneumatic structure 4 is connected to the first rigid support end face 2 and the lower end is connected to the second rigid support end face 3 while surrounding the rigid support structure 1, i.e. the rigid support structure 1 is located inside the flexible pneumatic structure 4, preferably in the region of the central axis of the flexible pneumatic structure 4.
As shown in fig. 1, in the present embodiment, the rigid support structure 1 has an interior space a for accommodating an astronaut, for the astronaut's life and activities, and for accommodating other items. Meanwhile, the rigid supporting structure 1 is provided with a cabin door, and the inner space B of the flexible inflatable structure 4 is communicated with the inner space A of the rigid supporting structure 1.
As shown in fig. 1, in the present embodiment, the internal space a of the rigid support structure 1 is composed of a first portion 101, a second portion 102, and a third portion 103, and as shown in fig. 1, the first portion 101, the second portion 102, and the third portion 103 are sequentially arranged in order from the upper end to the lower end of the rigid support structure 1 in fig. 1. Wherein the first part 101 and the third part 103 are used for accommodating the astronaut and for the astronaut to rest, work and other activities. The second part 102 is provided with instrument boards 5 for mounting various types of electrical functional equipment of the spacecraft, and as shown in fig. 1, the second part 102 is provided with three instrument boards 5 at intervals. In the present embodiment, the inner space B is communicated with the second portion 102, so that when the astronaut is in the inner space B, the operation, maintenance and other work can be performed on various equipment and instruments in the second portion 102.
In the present embodiment, as shown in fig. 1, a rigid door 201 is provided on the first rigid supporting end surface 2, and a docking mechanism 6 for docking a spacecraft and a sensor required for rendezvous and docking are further installed on the first rigid supporting end surface 2, and as shown in fig. 1, the rigid door 201 is located on the first rigid supporting end surface 2 at the inner central portion of the docking mechanism 6.
In addition to the above, the second rigid bearing end face 3 is provided with a mechanical interface and a power supply interface for mounting the propulsion and power generation equipment.
In combination with the above arrangement, in the present invention, the rigid support structure 1 is a main load-bearing structure of the living cabin, is located in the center of the living cabin, and is connected with the first rigid support end face 2 at the upper part and the second rigid support end face 3 at the lower part along the launching direction. The flexible inflatable structure 4 is an inflatable expansion structure, is arranged around the outer side of the rigid supporting structure 1, is folded when being launched, is wrapped on the outer side of the rigid supporting structure 1 and is inflated and expanded after entering the rail. The flexible inflatable structure 4 is rigidly and flexibly connected with the upper end surface and the lower end surface to form the sealed cabin.
The rigid structure 1 is provided with a passage for the passage of the astronauts to and from the living accommodation, i.e. the above-mentioned hatch 201. The rigid supporting structure 1 is of a truss structure, and an astronaut access passage is arranged on the side face of the truss, so that after the flexible inflatable structure 4 is inflated and unfolded, astronauts can enter the truss from the cabin door and enter a space between the flexible inflatable structure 4 and the rigid supporting structure 1.
The rigid supporting structure 1 is provided with a plurality of layers of instrument discs and is used for installing gas cylinders and gas charging equipment required by gas charging and unfolding, ring thermal control, information, power supply and distribution, passengers and other functional equipment. The docking mechanism and the rendezvous and docking sensor device are arranged on the upper end face (namely the first rigid support end face), and the functions of rendezvous and docking and the functions of entering and exiting the sealed cabin by astronauts and cargos are achieved. The lower end face (namely the second rigid supporting end face) is reserved with a connecting interface with the rigid cabin section and can be used for arranging equipment needing on-orbit maintenance and repair of astronauts and other platform equipment.
After the in-orbit inflation and unfolding, the astronaut can install equipment, pipelines, cables and the like on the flexible inflation structure 4 to support the resident and in-orbit maintenance tasks of the astronaut.
In addition, the instrument board is a rigid structure board, so that the equipment is convenient to mount and dismount. All equipment is installed in place before launching, inflation and unfolding of the flexible structure are not affected, maintainability design can be carried out, and equipment can be maintained and replaced on the rail. The living cabin has the capacity of supporting the work and the life of astronauts.
The rigid structure of the first rigid supporting end surface 2 can ensure the installation precision of the butt joint mechanism and the intersection butt joint sensor. The butting impact load is transmitted to the first rigid supporting end surface 2, the rigid supporting structure 1 and the second rigid supporting end surface 3 by the butting mechanism. The flexible inflatable structure 4 is not in the impact force transmission path during docking and is therefore subjected to a small impact force.
Furthermore, the second rigid bearing end face 3 can also be used for arranging equipment requiring on-track maintenance and repair by astronauts and other equipment of the platform.
According to the arrangement, the inflatable expanded living cabin provided by the invention can support the on-orbit work and life of astronauts without on-orbit installation equipment, adopts a rigid-flexible coupling design, adopts a rigid structure as a main bearing structure, can bear the butt joint impact load, and supports the on-orbit intersection butt joint of the spacecraft.
