Description

Technical Field

[0001] This invention belongs to the field of active interceptor warhead protection technology, and in particular, it is a protective device that can effectively suppress collateral damage caused by the explosion of an active interceptor warhead. Background Technology

[0002] Active interceptor warhead systems play a crucial role in tank defense systems, and the requirements for minimizing collateral damage to the vehicle itself from these warheads are increasingly stringent. Currently, most mainstream active interceptor warheads, both domestically and internationally, cause significant collateral damage to infantry fighting personnel and the vehicle itself upon detonation. Due to limitations in the protective structures of existing active interceptor warheads, these structures are unable to effectively reduce collateral damage when the warhead is activated. Therefore, there is an urgent need for a protective device that can effectively suppress collateral damage from active interceptor warhead explosions. This technology is not currently among the publicly available active interceptor warhead protection systems. Summary of the Invention

[0003] The purpose of this invention is to provide a protective device that suppresses collateral damage from the explosion of an active interceptor warhead. It achieves lateral pressure distribution by crushing ceramic blocks and protective plates, thereby reducing the radial pressure generated by the warhead explosion and thus achieving the protective function.

[0004] The technical solution to achieve the purpose of this invention is as follows:

[0005] A protective device for suppressing collateral damage from an active interceptor warhead explosion includes:

[0006] The barrier layer is used to withstand the detonation wave of the active interceptor warhead;

[0007] The H-shaped arc-shaped rib structure is set at the rear end of the barrier layer, which can produce a backward bending from the center to the edge after the barrier layer deforms.

[0008] Multiple ceramic frustum-shaped protective blocks are connected between the barrier layer and the honeycomb panel, with the front surface area being larger than the rear surface area; the height of the ceramic frustum-shaped protective blocks is greater than the height of the H-shaped arc rib structure, and the height and density of the ceramic frustum-shaped protective blocks located in the center are greater than those in the surrounding areas, which can form a ceramic cone under pressure.

[0009] Honeycomb panels are used to disperse and absorb impact forces;

[0010] Back panel, used to support the honeycomb panel and connect the figure-eight reinforced front end;

[0011] Multiple figure-eight-shaped stiffening structures are arranged symmetrically at the center. The rear end is used to connect with the vehicle body, and the rear end is tilted outward. Under pressure, the front end of the multiple figure-eight-shaped stiffening structures breaks laterally to absorb energy and reduce the deformation of the back plate.

[0012] The significant advantages of this invention compared to existing technologies are:

[0013] The invention designs a protective device to suppress collateral damage from the explosion of an active interceptor warhead. Through the energy absorption and fragmentation of the ceramic frustum-shaped protective block and the honeycomb panel, it can effectively reduce the collateral damage to the loading vehicle body caused by the warhead explosion. The pressure-driven lateral sliding fracture of the figure-eight reinforced structure can effectively achieve lateral pressure distribution, while the alternating use of steel and aluminum materials also gives it the advantage of low overall weight of the protective structure.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. The specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0020] like Figure 1-5 As shown, this embodiment of a protective device for suppressing collateral damage from an active interceptor warhead explosion comprises a barrier layer, a buffer layer, and a support layer. The barrier layer includes a steel protective block 1 and an aluminum protective front plate 2. The steel protective block 1 is embedded in the center of the aluminum protective front plate 2. The detonation center of the active interceptor warhead 8 (used to aid understanding of the overall invention, not the focus of this design) is located at the same position as the center of the protective block 1. The back of the aluminum protective front plate 2 is provided with an H-shaped arc-shaped rib structure 3, such as... Figure 3 The H-shaped arc-shaped rib structure 3 includes two parallel arc-shaped plates 301 and a horizontal plate connecting the two arc-shaped plates 301, forming an H-shaped structure. The arc-shaped plates 301 have the highest height at their center, gradually decreasing towards both sides. The height at the center is greater than that at the sides, causing the center to contact the honeycomb panel first, resulting in a backward bending from the center to the edges. After bending, the force is dispersed from the center to the sides (edges). The height of the horizontal plate is less than the height of the arc-shaped plates 301, and the distance between the two horizontal plates is less than the distance from the horizontal plate to the end of the arc-shaped plates 301.

[0021] The buffer layer includes a honeycomb steel plate 5 and multiple ceramic frustum-shaped protective blocks 4. The front surface area of ​​the ceramic frustum-shaped protective blocks 4 is larger than the rear surface area, forming a conical frustum structure. The front surface of the ceramic frustum-shaped protective blocks 4 is connected to the back surface of the protective front plate 2. Figure 4 The ceramic frustum block 4 has multiple straight grooves 31 evenly distributed along the circumference on its side. The ceramic frustum protective block 4 has a higher distribution density in the explosion center area than in the non-center area (peripheral area), and the frustum is higher (higher than the height of the peripheral area). The height of the ceramic frustum block 4 is greater than the height of the arc plate 301, and the height of the arc plate 301 is greater than the height of the horizontal plate. The rear surface of the ceramic frustum-shaped protective block in the central area is connected to the front surface of the honeycomb steel plate 5; the support layer is composed of an aluminum back plate 6 and a figure-eight reinforcing structure 7. Multiple figure-eight reinforcing structures 7 are symmetrically arranged about the center. In this embodiment, the back of the back plate 6 is provided with three sets of figure-eight reinforcing structures 7. The rear end of the figure-eight reinforcing structure 7 is inclined to the outside, and the inner side of the rear end is provided with an arc-shaped chamfer. The rear end is connected to the loading vehicle body by bolts. The three sets of figure-eight reinforcing structures 7 include a symmetrical first figure-eight reinforcing structure 402, a second figure-eight reinforcing structure 403, and a third figure-eight reinforcing structure 404. The first figure-eight reinforcing structure 402 is located in the center position. The second figure-eight reinforcing structure 403 and the third figure-eight reinforcing structure 404 are arranged sequentially outside the first figure-eight reinforcing structure 402. The inclination angle gradually decreases from the first figure-eight reinforcing structure 402 to the third figure-eight reinforcing structure 404.

[0022] like Figure 1As shown, when the active interceptor warhead 8 explodes, the steel protective block 1 of the front plate is the first to be impacted and deformed as the detonation wave propagates downwards. The aluminum protective plate 2 is then compressed and deformed, transmitting the compression wave to the front surface of the ceramic frustum-shaped protective block 4. The front surface has a larger contact area and can withstand greater pressure. A large compression wave is generated on the front surface of the ceramic frustum-shaped protective block 4. Part of the compression wave is transmitted and reflected at the rear surface of the ceramic frustum. The reflected wave and the compression wave superimpose and act together on the ceramic frustum-shaped protective block 4. When the stress on it exceeds the yield limit of the material, the internal cracks of the ceramic rapidly grow and break, eventually fracturing to form a ceramic cone. The ceramic cone and the cone of the ceramic frustum are oriented in opposite directions. In addition, the ceramic frustum-shaped protective block 4 has eight circumferentially evenly distributed straight grooves 31, making the ceramic frustum more prone to fragmentation, thereby absorbing energy. Because the number and height of the ceramic frustums in the explosion center region are greater, and because they are made of silicon carbide ceramic material with relatively higher toughness, there are more ceramic frustums in the center region than in the edge region. These frustums are more susceptible to the effects of compression and reflection waves and can withstand greater stress before fracturing. The detonation wave compresses the H-shaped arc-shaped rib structure 3 on the back surface of the front plate 2, causing it to bend backward perpendicular to the length of the arc-shaped plate 301. This makes it easier for the arc-shaped plate 301 to disperse the force to both sides after contacting the honeycomb steel plate 5. The H-shaped arc-shaped rib structure 3 and the ceramic frustums in the center act together on the front surface of the honeycomb steel plate 5. The honeycomb holes on the honeycomb steel plate 5 are frustum-shaped, which improves the compressive strength and bending stiffness of the honeycomb steel plate 5, helping to disperse and absorb the impact force. The honeycomb steel plate 5 transmits the pressure to the aluminum back plate 6, causing it to deform and bend under pressure. This pressure compresses the V-shaped stiffener 7, causing its front end to break laterally. The arc-shaped structure at the tail of the V-shaped stiffener 7 makes its front end more prone to lateral displacement and breakage, thus absorbing energy and reducing the deformation of the aluminum back plate 6. At the same time, the inclination angle of the inner V-shaped stiffener 402 gradually decreases towards the outer V-shaped stiffener 404, making the area of ​​the inner V-shaped stiffener structure subjected to higher impact force more prone to lateral displacement and breakage, while the outer V-shaped stiffener structure provides a certain degree of support.

[0023] Through the fracture, deformation, and fragmentation of the various components, the protective device can effectively absorb the radial pressure generated by the blast wave and convert it into lateral pressure, ensuring that the vehicle body itself will not deform due to the explosion of the warhead, thereby achieving the tactical target of reducing collateral damage to the vehicle body.

[0024] The technical solutions of the present invention are not limited to the specific embodiments described above. Any technical modifications made in accordance with the technical solutions of the present invention fall within the protection scope of the present invention.
