Description

Technical Field

[0001] The present invention relates to the technical field of ground target stealth, and in particular to a plasma jet coupled modular stealth structure. Background Art

[0002] Currently, conventional physical obscuration methods are commonly used to conceal important ground targets, such as using dense vegetation, large buildings, or applying radar-absorbing materials to the target surface. However, these methods only provide a limited degree of stealth and are unable to proactively adapt to changes in enemy radar parameters. Furthermore, they are labor-intensive and expensive. Furthermore, if the enemy possesses powerful radar detection capabilities, these conventional methods are virtually ineffective.

[0003] As an active anti-radar stealth technology, plasma stealth can adjust its parameters in real time based on enemy surveillance and radar parameter changes, fully maximizing its radar countermeasure capabilities. Plasma stealth technology also boasts a wide absorption bandwidth, high absorption rate, and excellent stealth performance. It absorbs not only microwaves but also infrared radiation. However, existing plasma stealth technology struggles to achieve plasma coverage across the entire target surface, and plasma discharges can only occur in selected areas, thus compromising stealth effectiveness.

[0004] In the prior art, the Chinese patent application with application number CN201910176804X and titled "A Low-Temperature Plasma Generator with Stealth Function" discloses that the device is composed of a discharge patch, an electromagnetic transparent medium layer, a carbon fiber discharge electrode and a metal conductive layer. The Chinese patent application with application number CN2020111275573 and titled "A Plasma and Photonic Crystal Composite Stealth Structure" discloses that the structure is composed of a plasma stealth layer and a photonic crystal stealth film. However, the disadvantages of the solutions provided by the above invention patents are: 1. Because the surface area of the large ground equipment target is too large and the shape is irregular, the plasma cannot completely cover the equipment surface. 2. If the large ground target moves, the installed plasma stealth device is inconvenient to disassemble and reinstall. 3. Due to the large target area, the plasma formed by the device cannot be always uniform and continuous. Summary of the Invention

[0005] The purpose of the present invention is to provide a plasma jet coupled modular stealth structure, which is spliced by multiple basic modules and can be freely arranged and laid on the target surface of large equipment of different shapes, and is easy to disassemble and install.

[0006] To achieve the above-mentioned purpose, the present application proposes a plasma jet-coupled modular stealth structure, comprising a plurality of plasma stealth modules laid on the surface of the equipment target, wherein one end of the plasma stealth module is provided with an outward-extending airway tube and the other end is provided with an air hole. Two adjacent plasma stealth modules are spliced and air is transported through the cooperation of the outward-extending airway tube and the air hole.

[0007] Furthermore, it also includes a hose, one end of which is sleeved on the extended airway pipe of one of the plasma stealth modules, and the other end of the hose extends into the air hole of the adjacent plasma stealth module.

[0008] Furthermore, when the plasma stealth module is implemented by structure a with good fixing effect, it includes a module body, in which multiple micropores are processed, the inner wall of the micropore is an insulating dielectric layer, the top of each micropore is connected to the negative electrode, the needle-shaped electrode of the positive electrode extends into the lower part of the micropore, the fixing seat of the needle-shaped electrode passes through the fixing hole at the bottom of the module body, and an injection port is opened at the top of the module body, which is located above the corresponding negative electrode.

[0009] Furthermore, the bottom side of the needle-shaped electrode is a pointed structure, which is interlocked with the fixing seat.

[0010] Furthermore, the negative electrode is fixed by a pressure cover, each pressure cover is provided with a through circular hole, a conductor is inserted into the circular hole so that it contacts the annular negative electrode, and the top of the conductor extends out of the upper surface of the module body and is connected together by a wire and connected to the external grounded negative electrode. The external grounded negative electrodes of each plasma stealth module are connected.

[0011] Furthermore, connecting channels are provided between the tops of the micropores in the module body, and the wires connect the negative electrodes together through the various connecting channels; the negative electrodes are fixed by means of pressure caps, one of which is provided with a through circular hole, into which a conductor is inserted so as to contact the corresponding circular negative electrode, and the top of the conductor extends out of the upper surface of the module body and is connected to the external grounded negative electrode, and the extended conductors of each plasma stealth module are connected.

[0012] Furthermore, the fixing seat of the needle-shaped electrode is inserted into the hole groove of the electrode plate laid on the target surface of the equipment. The discharge of the needle-shaped electrode will ionize the air entering the micropore through the air inlet into plasma, and the plasma is then ejected through the injection port. Multiple plasma stealth modules work together to make the target surface of the equipment covered with plasma.

[0013] Furthermore, when the plasma stealth module is realized by installing a simple structure b, it includes a module body, in which a plurality of micropores are processed, a negative electrode plate and an insulating medium layer are sequentially laid on the module body, the negative electrode plate has a through hole at each micropore position, and above the through hole is a nozzle arranged in the insulating medium layer, and a needle-shaped electrode is provided in the lower part of the micropore, and the needle-shaped electrodes are all connected to the fixed frame at the bottom.

[0014] Furthermore, a negative electrode extension tube is provided on one side of the negative electrode plate, which is inserted into the interior of the adjacent plasma stealth module and contacts the negative electrode plate of the module; a positive electrode extension tube is provided on one side of the fixed frame, which is inserted into the interior of the adjacent plasma stealth module and contacts the fixed frame of the module.

[0015] As a further step, the plasma stealth module is laid on the surface of the equipment target, and the positive extension tube at the end is connected to the external positive electrode. When the external electrode is energized, the needle-shaped electrode discharge ionizes the air entering the micropores from the air inlet into plasma, and the plasma is then ejected through the nozzle. Multiple plasma stealth modules work together to cover the surface of the equipment target with plasma.

[0016] The above technical solution adopted by the present invention offers the following advantages over existing technologies: The present invention utilizes plasma stealth modules as basic units, which can be assembled and laid out to form an array. Even if the target surface area is too large or irregularly shaped, the number and layout of plasma stealth modules can be controlled to achieve complete coverage. The modules work together to achieve the desired stealth effect. Furthermore, because the modules are assembled and spliced together, if a module becomes damaged or underpowered during use, only that module needs to be replaced, significantly reducing user convenience. Furthermore, the system is easily disassembled during installation and use, allowing for application to a variety of large-scale targets, significantly reducing costs and resource consumption.

[0032] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application. That is, the embodiments described herein are only some embodiments of this application, not all embodiments. Generally, the components of the embodiments of this application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present application.

[0034] The present application provides a plasma jet-coupled modular stealth structure, comprising a plurality of plasma stealth modules laid on the surface of an equipment target, wherein one end of the plasma stealth module is provided with an extended airway tube and the other end is provided with an air hole. Two adjacent plasma stealth modules are spliced and air is transported through the cooperation of the extended airway tube and the air hole.

[0035] Preferably, it further comprises a hose, one end of which is sleeved on the outwardly extending airway pipe of one of the plasma stealth modules, and the other end of which extends into the air hole of the adjacent plasma stealth module.

[0036] Multiple plasma stealth modules are assembled and laid on the target surface, providing comprehensive coverage. If the target surface is irregular, a flexible hose can be attached to the extended airway tube of the plasma stealth module to connect adjacent modules. The hose can be shaped as needed. In this case, adjacent modules are no longer tightly pressed together, but instead form an angle to accommodate angled areas on the target surface. The hose then acts as a seal for the air holes and transports air.

[0037] When a piece of equipment requires stealth, simply select the appropriate number of plasma stealth modules, place them on the target surface, and activate them to unleash their stealth capabilities. When stealth is no longer needed, simply remove the modules covering the surface. Furthermore, because the stealth structure is modular, rather than designed independently based on the equipment's appearance, the plasma stealth modules of one piece of equipment can be removed and reapplied to other equipment. And because the modules are integrated yet operate independently, if a problem arises with a particular part or module, simply replace the corresponding module.

[0038] Example 1

[0039] like Figure 1-7 As shown, when the above-mentioned plasma stealth module is realized by structure a with good fixing effect, it includes a module body, in which a plurality of micropores are processed, the inner wall of the micropore is an insulating medium layer, the top of each micropore is connected to the negative electrode, the needle-shaped electrode of the positive electrode extends into the lower part of the micropore, the fixing seat of the needle-shaped electrode passes through the fixing hole at the bottom of the module body, and an injection port is opened at the top of the module body, and the injection port is located above the corresponding negative electrode.

[0040] In order to reduce the resistance of the air and make the air enter the ionization space in the micropores better, the bottom side of the needle-shaped electrode is a pointed structure, which is clamped with the fixing seat.

[0041] Preferably, the negative electrode is fixed by a pressure cover, each pressure cover is provided with a through circular hole, a conductor is inserted into the circular hole so that it contacts the annular negative electrode, and the top of the conductor extends out of the upper surface of the module body and is connected together by a wire and connected to the external grounded negative electrode. The external grounded negative electrodes of each plasma stealth module are connected.

[0042] Preferably, connecting channels are provided between the tops of the micropores in the module body, and the negative electrodes are connected together by wires through the various connecting channels; the negative electrodes are fixed by means of pressure caps, one of which is provided with a through circular hole, into which a conductor is inserted so as to contact the corresponding annular negative electrode, and the top of the conductor extends out of the upper surface of the module body and is connected to the external grounded negative electrode, and the extended conductors of each plasma stealth module are connected.

[0043] When in use, the fixing seat of the needle-shaped electrode is inserted into the hole groove of the electrode plate laid on the target surface of the equipment. The electrode plate can not only energize the module but also play a fixing role, which facilitates the installation of the module.

[0044] Example 2

[0045] like Figure 8-13 As shown, when the above-mentioned plasma stealth module is realized by installing a simple structure b, it includes a module body, in which a plurality of micropores are processed, and a negative electrode plate and an insulating medium layer are sequentially laid on the module body. The negative electrode plate has a through hole at each micropore position, and above the through hole is an injection port arranged in the insulating medium layer. A needle-shaped electrode is provided in the lower part of the micropore, and the needle-shaped electrodes are all connected to the fixing frame at the bottom.

[0046] A negative electrode extension tube is installed on one side of the negative electrode plate, inserted into the interior of the adjacent plasma stealth module and in contact with the negative electrode plate of that module. A positive electrode extension tube is installed on one side of the fixed frame, inserted into the interior of the adjacent plasma stealth module and in contact with the fixed frame of that module. Adjacent modules are interconnected by plugging the positive and negative electrode extension tubes into the extended airway tube, allowing the electrodes of each module to penetrate and work together, facilitating overall control, fault detection, and maintenance.

[0047] The figure shows only nine micropores, which are cylindrical and run through the module. Electrodes are distributed above and below the micropores. When the electrodes are energized, there are positive and negative electrodes around each micropore. The air entering through the air inlet is ionized in the micropore to form plasma, which is then ejected through the injection port at the upper end of the micropore. The plasma ejected from several micropores covers a wide range, such as Figure 14As shown in the figure, multiple basic modules operating simultaneously can completely cover the equipment surface, rendering large ground targets invisible. Because the plasma jets generated by the modules are ejected outward, the area of plasma ejected from each jet nozzle is much larger than the nozzle area. Consequently, the total jet area generated by each module is also larger than the module itself, thus ensuring the reliability of the module's stealth function.

[0048] The foregoing descriptions of specific exemplary embodiments of the present invention are for purposes of illustration and description. These descriptions are not intended to limit the invention to the precise forms disclosed, and it is apparent that many variations and modifications are possible in light of the foregoing teachings. The exemplary embodiments have been selected and described for the purpose of explaining the specific principles of the invention and their practical application, thereby enabling those skilled in the art to realize and utilize a variety of exemplary embodiments of the invention and various options and modifications. The scope of the invention is intended to be defined by the claims and their equivalents.
