All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present application based on the embodiments herein.
The embodiment of the application provides a spacecraft and a thermal resistance type end cap mounting structure thereof, which are used for solving the problem that equipment in a rear cabin section is failed due to the fact that a nose cone part of the spacecraft made of a high-temperature alloy material transfers heat to the rear cabin section in the related technology.
Referring to fig. 1, a thermal resistance type end cap mounting structure includes an end cap 1, a first heat insulating member 2, a rear compartment section 3, a second heat insulating member 5, a third heat insulating member 6, and a connecting member 7;
wherein the end cap 1 is hollow, and the end part is provided with an opening, which is a high-temperature alloy material with good high-temperature resistance; the inside of the rear cabin section 3 is hollow, and the end part for contacting with the end cap 1 is also provided with an opening, so that the weight reduction problem of the aircraft is considered, and therefore, the heat transfer of the end cap 1 into the rear cabin section 3 is in two forms, one is that the end cap 1 is directly contacted with the rear cabin section 3, and the direct conduction is carried out through structural materials; the other is that after the spaces in the end cap 1 and the rear cabin section 3 are communicated, heat transfer is performed in the form of heat radiation.
For the former case, where heat transfer is performed directly, there is another case where, since the end cap 1 and the rear compartment 3 are connected by the connection member 7, a part of the connection member 7 is extended into the bulkhead of the rear compartment 3, and heat is transferred to the rear compartment through the connection member 7.
The following specific settings were thus made:
the second heat insulation member 5 is arranged between the end cap 1 and the rear cabin section 3 to form a heat radiation barrier layer; a third thermal insulation 6 is provided between the end cap 1 and the rear section 3 to form a heat conduction barrier layer covering the heat radiation barrier layer. The connection member 7 penetrates the first and third heat insulating members 2 and 6 and connects the end cap 1 and the rear compartment section 3 to insulate heat from direct conduction and heat radiation.
The first heat insulating piece 2 is arranged in the end cap 1, the first heat insulating piece 2 reduces the contact between the connecting piece 7 and the inner wall of the end cap 1, and the vast majority of the connecting piece 7 at one end of the end cap 1 is wrapped, so that the heat transfer area is reduced, and the heat transfer is reduced.
The number of the connectors 7 can be plural and distributed on a circle centered on the center of the end face of the end cap 1 and uniformly spaced. The number of first heat insulating members 2 corresponds to the number of connecting members 7.
Therefore, through the structural arrangement, the heat transferred from the end cap 1 to the rear cabin section 3 is greatly reduced, the structure is simple, the original connection mode of the end cap 1 and the rear cabin section 3 is not affected, and the heat resistance reliability is stable.
In some preferred embodiments, to facilitate the installation of the second insulation 5 and the docking of the end cap 1 with the rear section 3, a mounting groove 4 is provided on the end of the end cap 1 or the rear section 3, which does not require docking during installation, saving the steps of installation.
Further, wherein the mounting groove 4 includes an annular groove 41 and a circular groove 42, the annular groove 41 and the circular groove 42 are concentrically arranged, and a radius of the annular groove 41 is larger than a radius of the circular groove 42; the opening on the end of the end cap 1 or the rear section 3 is located in the circular groove 42;
the second heat insulating piece 5 comprises sealing glue and a heat insulating block, the sealing glue is filled in the annular groove 41, the heat insulating block is positioned in the circular groove 42, so that the sealing glue can ensure the tightness of the joint between the end cap 1 and the rear cabin section 3, heat transfer can be reduced, the heat insulating block separates the space between the end cap 1 and the rear cabin section 3, and due to the arrangement of the circular groove 42 and the annular groove 41, the heat insulating block and the sealing glue are placed in advance when the end cap 1 and the rear cabin section 3 are connected, and then only the joint is needed.
The sealant is a high-temperature putty material, has high temperature resistance and sealing performance, and the heat insulation block is a SiO2 aerogel material with excellent heat insulation property;
further, a third heat insulating member 6 covers the end of the end cap 1 or the rear cabin section 3, and is a heat insulating cloth, and can be connected with the rear cabin section 3 in a sealing manner through a sealant, and the heat insulating block is fixed in the circular groove 42. The heat insulation cloth is B-type quartz fiber cloth with excellent heat insulation performance, so that the end cap 1 and the rear cabin section 3 are not directly connected.
In some preferred embodiments, the connection 7 may be a high strength bolt, one end of which has a head located within the tip cap 1; the first heat insulation piece 2 is provided with a sinking groove for accommodating the head part of the high-strength bolt, namely the sinking groove is a hexagonal groove; the first heat insulating piece 2 can enclose the side edge and one side of the high-strength bolt, so that heat transfer is avoided.
Further, the mounting structure further comprises a flexible gasket 8, wherein the flexible gasket 8 is arranged between the first heat insulation piece 2 and the inner wall of the end cap 1, the flexible gasket 8 is made of red copper material, has good ductility and is softer in texture, is mounted between the first heat insulation piece 2 and the end cap 1 and is used for adapting to thermal deformation of the end cap and preventing connection looseness.
In some preferred embodiments, the end cap 1 and the rear compartment 3 may be of the same cross-sectional area, but in this way heat may enter from the whole body of the rear compartment 3, transferring heat, plus heat generated by friction with air, and thus the following arrangement is also made:
the rear cabin section 3 is coated with a heat-proof layer 9, and the sum of the end areas of the heat-proof layer 9 and the rear cabin section 3 is equal to the end area of the end cap 1; at this time, the third heat insulating member 6 covers the end of the rear cabin section 3, but does not cover the end of the heat insulating layer 9, and the heat insulating layer 9 can be made of high-temperature resistant and ablation resistant phenolic resin heat insulating material, so that the whole body of the rear cabin section 3 can be protected and thermally isolated, and the end, which is contacted or close to the end cap 1, of the rear cabin section 3 is comprehensively thermally isolated and protected by being matched with the third heat insulating member 6, so that the heat insulating effect is greatly improved.
The application also proposes a spacecraft comprising: the thermal resistance type end cap mounting structure.
