Description

TECHNICAL FIELD

[0001] The present application belongs to the field of infrared camouflage stealth technology, and particularly relates to a compress-resistant aerogel infrared camouflage stealth mesostructure. BACKGROUND

[0002] Combat personnel generally adopt traditional methods such as reducing temperature, improving design, and relying on coating to reduce infrared radiation and evade discovery by infrared detection equipment. However, as a homeothermic animal, the heat generated by the human body itself causes a large thermal load with the accumulation of time in the case of thermal conduction insulation, affecting combat effectiveness.

[0003] Aerogel has very good heat insulation capacity and strong infrared stealth application prospects, but is relatively brittle and is easily broken under pressure, losing the heat insulation performance. To use aerogel for infrared stealth, the brittleness problem needs to be solved or a support needs to be provided to avoid the aerogel from being crushed under external pressure. SUMMARY

[0004] OBJECTIVE

[0005] To solve the problem that aerogel is easily broken under pressure, the present application provides a compress-resistant aerogel infrared camouflage stealth mesostructure.

[0006] TECHNICAL SOLUTION

[0007] A compress-resistant aerogel infrared camouflage stealth mesostructure comprises an aerogel layer and a solar film arranged in close contact, and a plurality of flow guide holes penetrating the aerogel layer and the solar film, the flow guide holes being used to support the entire structure.

[0008] Preferably, the end of the flow guide hole slightly protrudes from the outer surface of the aerogel layer.

[0009] Preferably, the flow guide hole comprises an inner wall and an outer wall, the inner wall is located in the inner hole of the outer wall, and a cavity is formed between the inner wall and the outer wall, and a water-absorbing resin is arranged in the cavity, the water-absorbing resin being connected to the inner wall and the outer wall.

[0010] Preferably, the thickness of the cavity gradually decreases from one end of the aerogel layer to the other end of the solar film.

[0011] Preferably, a plurality of water-absorbing resins are arranged in the cavity along the axial direction, and a gap is formed between adjacent two water-absorbing resins.

[0012] Preferably, the cavity is circumferentially divided into 8 parts, and water-absorbing resins are arranged in 4 of the 8 parts.

[0013] Preferably, the axis of the inner wall coincides with that of the outer wall.

[0014] Preferably, the flow guide holes are arranged in the overall structure as camouflage images that can confuse infrared detection equipment.

[0015] Preferably, the pattern of the arrangement of the flow guide holes matches the mission execution environment.

[0016] Advantages of the present application:

[0017] (1) The present application utilizes the thermal insulation capability of aerogel, and supports the aerogel main body in a structural composite manner, solving the problem of brittleness and easy fragmentation of aerogel itself, and providing a composite stealth solution for thermal insulation, sweat conduction, heat dissipation, and solar light absorption.

[0018] (2) Combined with the characteristics of solar thin film and aerogel, the high transmission characteristics of aerogel are utilized to realize solar energy collection and conversion. Compared with traditional infrared stealth coatings, the energy storage function is increased, the high temperature resistance is improved, and the use range is expanded.

[0019] (3) The present application can be used for stealth protection of combat personnel such as airborne troops and marine corps, combat systems that may be scanned by radar systems such as protective armor and stealth fighter jet exhaust ports, and other equipment surfaces that can be solar converted and infrared stealth.

[0024] The present application is realized by the following technical solutions.

[0025] As Figure 1 , an extrusion-resistant aerogel infrared camouflage stealth mesostructure, the aerogel 1 is located on the upper layer, the solar thin film 2 is located on the lower layer, and the flow guide holes 3 penetrate the upper and lower layers, and when in use, the lower layer is attached to the surface of the infrared camouflage object (such as combat personnel, etc.).

[0026] The flow guide hole 3 is composed of water-absorbing resin 4, inner wall 5 and outer wall 6, and the water-absorbing resin 4 is located between the inner wall 5 and the outer wall 6. The thickness of the inner wall 5 and the outer wall 6 is micron level and has sufficient rigidity, which supports the entire aerogel infrared camouflage mesostructure, and high rigidity light weight materials can be used.

[0027] The upper edge of the flow guide hole 3 is slightly higher than the aerogel 1, and when extruded by external force, it plays a supporting role. The lower edge of the flow guide hole 3 penetrates through the solar film 2, and in actual use, it is close to the surface of the human body.

[0028] The cavity surrounded by the inner wall 5 and the outer wall 6 is evenly divided into 8 parts, and the water-absorbing resin 4 is distributed in the cavity. The cavity is the space reserved for the water-absorbing resin 4 to absorb water and swell. The cavity is thick at the top and thin at the bottom, which can quickly absorb the sweat on the surface of the combat personnel and conduct it outward.

[0029] The inner wall 5 forms a large hole at the top and a small hole at the bottom, which quickly conducts the heat on the surface of the combat personnel.

[0030] The flow guide hole 3 is arranged according to a certain pattern in the overall structure, forming a camouflage image that can confuse infrared detection equipment, realizing infrared camouflage and stealth. The design of the pattern should match the task execution environment, or be relatively common / widely existing, such as trees / buildings / infrastructure, etc.

[0031] The aerogel 1 has high transmittance to sunlight, and the solar film 2 collects sunlight and converts it into electrical energy, providing power for the use of electronic devices by combat personnel, further reducing the thermal impact of sunlight on infrared camouflage and stealth.

[0032] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent transformation or modification made according to the spirit and essence of the present application should be covered within the protection scope of the present application. The technical, shape, and structure parts not described in detail in the present application are all known technologies.
