Description

Technical Field

[0001] The present invention relates to the technical field of aerostat antennas, and in particular to an aerostat conformal antenna system. Background Art

[0002] Aerostats can be deployed stably at a specified altitude for a long time. They carry various optical, electronic and other functional equipment, providing a potential economical and applicable platform for earth observation, communication relay and other fields. The rigid structure of traditional antennas mounted on the flexible capsule structure of the aerostat will cause problems such as contact interface separation, stress concentration and even capsule structure damage.

[0003] In recent years, driven by the engineering application requirements of lightweight, integrated and integrated platform loads, the concept of conformal antennas for aerostats has been proposed. Conformal antennas are antennas or antenna arrays that are consistent with the flexible surface structure of the aerostat carrier and do not introduce additional burdens to the carried object. It can realize the navigation, communication, positioning and other functions of traditional antennas without affecting the carrier's external structure and aerodynamic characteristics.

[0004] Among the related technical solutions, one type is a conformal antenna attached to a rigid structure; the other type is a fully flexible conformal antenna. However, these conformal antennas cannot adapt to the application scenarios of airships. The working environment of the airship requires that the conformal antenna can withstand large stretching, bending, and torsion without damage, and have a certain rigidity to maintain a good working condition. For conformal antennas attached to rigid structures, the antenna structure itself is relatively fragile and mainly relies on the rigid structure to which it is attached to withstand deformation. Therefore, this type of conformal antenna cannot withstand large stretching, bending, torsion and other deformations; for fully flexible antennas, the flexibility of the material makes the antenna itself not too rigid, so it is difficult to maintain a good working condition in the working environment of the airship. Therefore, there is an urgent need for a conformal antenna system that can maintain a good working condition while being flexible. Summary of the invention

[0032] Aerostats can be equipped with various optical, electronic and other functional equipment to provide a platform for ground observation or communication relay. Such aerostats usually need to be equipped with antennas to transmit information. When the traditional antenna structure is connected to the flexible capsule structure of the aerostat, problems such as interface separation, stress concentration and even capsule structure damage will occur, which will cause the antenna to lose its use value.

[0033] In order to solve the problem of connecting traditional antennas with aerostats, the following two solutions are usually adopted in the related technology. One is a conformal antenna attached to a rigid structure, such as a conformal antenna used on the wings of high-altitude fixed-wing UAVs; the other is a fully flexible conformal antenna, such as a flexible conformal antenna with polyimide as the dielectric substrate. Among these types of conformal antennas, some achieve the structural flexibility of the antenna by changing the cross-sectional thickness of the antenna structure, so that it can be attached to a rigid structure to achieve conformality; some achieve the material flexibility of the antenna by changing the material of the antenna structure, so that it has a certain limit of stretching, bending and even twisting capabilities. However, these conformal antennas cannot adapt to the application scenarios of aerostats. The working environment of the aerostat requires that the conformal antenna can withstand large stretching, bending, and twisting without damage, and have a certain rigidity to maintain a good working condition. For conformal antennas attached to rigid structures, the antenna structure itself is relatively fragile and mainly relies on the rigid structure to which it is attached to withstand deformation. Therefore, this type of conformal antenna cannot withstand large deformations such as stretching, bending, and torsion. For fully flexible antennas, the flexibility of the material makes the antenna itself not very rigid, so it is difficult to maintain a good working state in the working environment of the aerostat. In response to the above problems, the conformal antenna system provided by the present invention can withstand large deformations such as stretching, bending, and torsion, and can use the support frame to achieve a certain degree of rigidity, thereby maintaining a good working state.

[0034] Regarding the problems in related technologies, such as Figure 1-Figure 4As shown, this embodiment provides a conformal antenna system 10 for an aerostat, comprising a support frame 11, an antenna body 13 and a capsule lining cloth 12 made of composite materials, a flexible connection assembly is provided on the support frame 11, the flexible connection assembly has a first connection portion 151 and a second connection portion 152, the antenna body 13 is connected to the first connection portion 151 and is located in the support frame 11, the capsule lining cloth 12 is connected to the second connection portion 152, and at least a portion of the capsule lining cloth 12 is located outside the support frame 11; wherein, the antenna body 13 comprises a plurality of active antenna modules, and the plurality of active antenna modules are arranged in an array, and a pull tab 14 is provided on the capsule lining cloth 12 located outside the support frame 11, and the pull tab 14 is used to cooperate and fix with the aerostat. In normal operation, since the capsule itself is a balloon-like structure of the aerostat, it needs to withstand large tensile, bending and torsional forces in the working state, while the conventional antenna will cause the use of the normal function of the antenna when stretched, bent and torsion. In this embodiment, by providing the support frame 11 and the flexible connection assembly, the overall antenna system can withstand greater tensile, bending and torsional forces, and can maintain the antenna body 13 in a good usage state.

[0035] Specifically, the composite support frame 11 has high strength and rigidity while maintaining appropriate flexibility and toughness, which allows the support frame 11 to undergo large deformations without damaging the structure of the support frame 11 itself. The support frame 11 can provide support when subjected to large tensile, bending and torsional forces, and finally return to its original shape to ensure that the antenna body 13 has a good working shape.

[0036] Furthermore, the antenna body 13 adopts a conventional flexible antenna. Specifically, the antenna body 13 adopts a polyimide aluminum-plated film as a substrate to serve as a flexible antenna. When connected, the substrate is connected to the support frame 11, so that the antenna body 13 is placed in the support frame 11. It should be known that the present invention adopts an existing conventional antenna body, and its specific structure is a conventional structure in the art, so it will not be described in detail here.

[0037] It is understandable that the working form of the antenna will affect the use of the normal function of the antenna. For example, if the shape of the flexible antenna is wrinkled, stretched or deformed, it will have a certain negative impact on its performance, especially in terms of impedance matching, radiation characteristics, frequency response and electrical performance. In the daily operating environment of the aerostat, the shape of the flexible antenna will often change. In this embodiment, the support frame 11 has a certain rigidity and toughness, which enables the support frame 11 to fit with the aerostat by undergoing a certain deformation. After the deformation occurs, since the support frame 11 itself has a certain structural strength, it can quickly return to its original shape to ensure that the antenna body 13 has a good working shape and achieves high-performance operation.

[0038] The flexible connector 15 is used to realize the connection between the antenna body 13 and the support frame 11, and also to realize the connection between the capsule lining 12 and the support frame 11. Compared with the rigid connection, it can avoid damage to the antenna body 13 and the support frame 11 when tension or torsion occurs, so as to protect the support frame 11 and the antenna body 13.

[0039] In specific configuration, the flexible connector 15 can be made of a variety of materials, such as woven fabric, thermoplastics, rubber, etc. That is, in this embodiment, as long as the flexible material can be connected to the antenna body 13 and the capsule lining 12, the specific material is not limited.

[0040] Furthermore, if Figure 1 , Figure 7 As shown, the antenna body 13 includes a plurality of L1×L2 rectangular active antenna module subarrays, and the plurality of active antenna modules in each active antenna module subarray are electrically connected by cables. Specifically, a plurality of active antenna modules are arrayed in a rectangular manner to form an active antenna module subarray, and each array module includes a plurality of active antenna module subarrays, and each active antenna module subarray is formed by a plurality of active antenna modules connected by cables. For example, each active antenna module subarray is provided with 10 active antenna modules, and the size of each active antenna module subarray is 1m 3m, and there is a safety spacing between adjacent sub-arrays, which is 10cm. Of course, the number, size and spacing of the aerostat conformal antenna sub-arrays are not limited to the above data.

[0041] According to some implementations provided by the present invention, Figure 2 , Figure 4 As shown, the support frame 11 includes a support tube 111 made of carbon fiber and a joint, and a plurality of support tubes 111 and joints are connected to form a receiving space 112 for receiving the antenna body 13 in the support frame 11. The carbon fiber itself has very high rigidity and strength, and its elastic modulus is relatively high, so that after being connected to form the support frame 11 structure, it can undergo a certain elastic deformation without damaging the overall structure, and in this way, the antenna body 13 can be well protected and restored to its original shape.

[0042] Specifically, the support tube 111 and the joint are made of carbon fiber, which has good recovery performance. Specifically, the structure is connected to the end of the support tube 111 to connect multiple support tubes 111 to form a main frame, and to have a receiving space 112 for installing the antenna body 13. And the support frame 11 can have a certain bending flexibility, which can adapt to the curvature change of the surface of the airship capsule. Of course, this curvature change is generally not large (the curvature change range is 0~5 degrees), so as to ensure the shape of the antenna body 13 and conform to the curved surface of the airship capsule surface.

[0043] like Figure 2 , Figure 6 As shown, the joint includes an L-shaped joint 113 and a T-shaped joint 114, and the L-shaped joint 113 and the T-shaped joint 114 are connected to the two ends of the support tube 111 to form a main frame structure. Specifically, three support tubes 111 are first selected, and the end of each support tube 111 is connected to the T-shaped joint 114, and then eight support tubes 111 are selected, and the end of each support tube 111 is respectively connected to the T-shaped joint 114 to enclose the middle part of the "mesh"-shaped structure. Further, two support tubes 111 are selected, and the end of each support tube 111 is connected to the L-shaped joint 113 to enclose the two side parts of the "mesh"-shaped structure. Further, the middle part enclosed by the T-shaped joint 114 is connected to the two side parts enclosed by the L-shaped joint 113, forming a support frame 11 structure similar to a "mesh"-shaped structure.

[0044] The connection method through the T-shaped connector 114 can realize the extension of the support frame 11 , ensure the overall structural strength of the support frame 11 , and realize the stable connection of the antenna body 13 .

[0045] In some embodiments, a flexible connection component is provided on each support tube 111 forming the accommodation space 112. That is, a flexible connection component is provided on each side of the accommodation space 112, which can make the connection of the antenna body 13 more secure and improve the stability of the connection of the antenna body 13.

[0046] Specifically, if Figure 2 , Figure 4 As shown, a flexible connection component is provided on each side of the accommodating space 112 of the "mesh"-shaped structural support frame 11, and the four sides of the rectangular antenna body 13 are connected to the first connection part 151 of the flexible connection component to enhance the connection structure strength of the antenna body 13.

[0047] In a specific configuration, the substrate of the antenna body 13 is connected to the first connecting portion 151 , which may be bonded by applying glue or by other fixed connection methods.

[0048] According to some embodiments provided by the present invention, Figure 3 As shown, the flexible connection assembly includes a cloth sleeve, on which is provided a first skirt for serving as a first connection portion 151, and a second skirt for serving as a second connection portion 152. The two skirts can be used as connection portions, and the antenna body 13 and the capsule lining cloth 12 are connected to the skirt structure, which is conducive to the connection with the antenna and the capsule lining cloth 12, and can play a role of flexible connection, and the overall structure is simple and the preparation difficulty is low.

[0049] Specifically, the cloth cover is made of woven material, and the cloth cover can be arranged on the support tube 111 by bonding or sleeve connection. The first skirt and the second group edge on the cloth cover respectively extend to the outside of the cloth cover, so as to be connected to the antenna body 13 and the capsule lining cloth 12.

[0050] like Figure 4 , Figure 5 As shown, in the specific setting, the carbon fiber support tube 111 is connected through an L-shaped joint 113, a T-shaped joint 114 and a heat shrink tube, and adhesive is applied inside the L-shaped joint 113 and the T-shaped joint 114, and the end of the support tube 111 is inserted into the L-shaped joint 113 and the T-shaped joint 114 to achieve the connection between the joint and the support tube 111. When the cloth sleeve is connected, the cloth sleeve is set on the outside of the support tube 111, and the outer surface of the L-shaped joint 113 and the T-shaped joint 114 is coated with adhesive, and the two ends of the cloth sleeve are glued to the L-shaped joint 113 and the T-shaped joint 114. The heat shrink tube is heat-shrunk at the connection between the L-shaped joint 113, the T-shaped joint 114 and the support tube 111 using a hot air gun to ensure the stability of the connection. In this way, the stable connection of the cloth sleeve can be achieved, so that the overall structural stability is better.

[0051] In some embodiments, the first skirt is located above the second skirt. The vertical spatial arrangement of the two skirts can provide a certain degree of protection, thereby protecting the antenna body 13.

[0052] like Figure 3 As shown, the first skirt is arranged toward the accommodating space 112, and the second skirt is arranged away from the accommodating space 112. Both the first skirt and the second skirt are made of woven cloth, and the first skirt is located in the tangent direction of the top of the cloth cover, and the second skirt is located in the tangent direction of the bottom of the cloth cover. This enables the twisting action of the skirt to reduce the amplitude of the stretching, bending or twisting when the bag lining cloth 12 is stretched, bent or twisted, thereby achieving protection for the antenna body.

[0053] It is understandable that when the antenna body is rigidly connected, the stretching, bending and twisting of the aerostat capsule will be directly transmitted to the antenna body, which will damage the antenna body. In this embodiment, since the antenna body and the capsule lining 12 are connected by the skirt structure, the transmission of stretching, bending and twisting can be weakened.

[0054] In some embodiments, the second skirt is connected to the bladder body lining cloth 12 via a quick-connect assembly. Through the provision of the quick-connect assembly, it can achieve a quick connection with the bladder body lining cloth 12.

[0055] Specifically, the quick connection assembly is connected to the second skirt and the bladder body lining 12, and the quick connection is achieved through the cooperation thereof. For example, a zipper, a snap button, etc. can be provided on the first skirt and the bladder body lining 12 for quick connection.

[0056] In the specific configuration, the quick-connect assembly includes a hook-surface buckle 153 and a fleece-surface buckle 154, and the hook-surface buckle 153 is bonded with the fleece-surface buckle 154. The configuration of the hook-surface buckle 153 and the fleece-surface buckle 154 can realize a quick connection between the two, and this method has higher stability.

[0057] Specifically, the hook-surface fastener 153 is arranged on the second skirt, and the fleece-surface fastener 154 is arranged on the bladder body lining cloth 12 , wherein the fleece-surface fastener 154 is connected to the bladder body lining cloth 12 by means of knitted sutures 155 . Of course, the hook-surface fastener 153 can also be connected by means of knitted sutures 155 .

[0058] like Figure 3 As shown, the fleece buckle 154 is arranged on the connecting part, the connecting part is made of woven material, one end of the connecting part is connected to the fleece buckle 154, and the other end of the connecting part is connected to the bladder lining cloth 12, so that the second skirt and the bladder lining cloth 12 can be quickly connected.

[0059] According to some embodiments provided by the present invention, the bladder lining cloth 12 covers the entire support frame 11, and the bladder lining cloth 12 is consistent with the bladder material of the aerostat. When specifically connected, the bladder lining cloth 12 contacts the outer surface of the bladder of the aerostat, and the bladder lining cloth 12 covers the entire support frame 11, so that after being installed on the aerostat, the overall structural stability is higher.

[0060] In addition, by limiting the material of the bladder lining cloth 12, the bladder lining cloth 12 and the bladder have the same tensile strength, elongation and rigidity, ensuring that the entire bladder will not be unevenly deformed or subjected to excessive local force after inflation, thereby improving its stability.

[0061] According to some embodiments provided by the present invention, the pull tab 14 is constructed as a V-shaped structure, and the pull tab 14 is welded to the capsule lining 12. When the conformal antenna is mounted on the capsule of the aerostat, the pull tab 14 is used as a force-bearing connector to achieve its installation.

[0062] Specifically, a plurality of pull tabs 14 are arranged in parallel on the capsule lining cloth 12 . The plurality of pull tabs 14 can realize stable connection of the conformal antenna. The pull tabs 14 are welded to the capsule lining cloth 12 by heat welding.

[0063] It can be understood that, by providing the pull tab 14 , when connected to the airship bladder, it can achieve a flexible connection with the airship, thereby further reducing the transmission of the stretching, bending and torsion of the bladder.

[0064] Through the description of the above embodiments, those skilled in the art can clearly understand that each embodiment consists of four parts: an antenna body 13, a support frame 11, a pull tab 14, and a capsule lining cloth 12. The conformal antenna system 10 designed by the method can withstand large deformations such as stretching, bending, and torsion through flexible structures such as the capsule lining cloth 12 and the pull tab 14, and can also achieve a certain rigidity by using the support frame 11, thereby maintaining a good working state. Compared with traditional rigid antennas, the antenna system designed by the method can fit tightly with the capsule structure of the airship, and has the advantages of flexibility, large area, high performance, stability, low consumption, and light weight. Furthermore, the conformal antenna system 10 provided by the present invention can withstand large deformations such as stretching, bending, and torsion through flexible structures such as the capsule lining cloth 12 and the pull tab 14, and can also achieve a certain rigidity by using the support frame 11, thereby maintaining a good working state.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
