Description

  The present invention relates generally to the technical field of protecting an armored vehicle or armor structure from a flying kinetic energy penetration bullet (KEP) or high energy anti-tank (HEAT) warhead. More specifically, the present invention relates to a technique for protecting an armored vehicle or an armor structure from a flying tandem warhead.

  In essence, HEAT ammunition operates by penetrating the armored vehicle's exterior and acts to kill internal occupants, shut down critical mechanical systems, or both.

  In order to allow an armored vehicle to withstand the impact of a molded glaze-mounted HEAT, an exterior explosive element named Explosive Reactive Armor (ERA) is attached to the armor of the vehicle.

  Standard ERA is made of a highly explosive sheet or rolled steel sheet, sandwiched between two sheets of metal, usually called reactive or dynamic elements.

  In one example, in order to neutralize a flying rocket-propelled HEAT, such as RPG-7, at the time of a collision, the high-performance explosive of the reactive armor explodes, and the metal plate of the reactive armor is replaced with a molded glaze. Forced to fire toward a jet (high-speed jet). The fired plate collapses the metal jet penetration.

  In one example of the prior art, the remarkable effectiveness of the ERA is mainly due to two basic mechanisms. First, the moving plate changes the effective speed and angle at the time of collision of the shaped glaze jet. As a result, the incident angle of the jet is changed, thereby reducing the degree of concentration of the jet. Second, the plate is angled with respect to any impact direction of the molded glaze warhead, and since the plate is normally moving outward, the impact point on the plate is As time changes, the jet needs to travel while cutting another new part of the plate. By this second effect, the effective plate thickness during the collision is greatly increased.

  Further, the ERA has been proved to be very effective in intercepting a single-stage rocket-propelled HEAT molded warhead such as RPG7, TOW, and LOW.

  Also, soldiers often use rocket-propelled HEAT for intercepting armored vehicles, and a new warhead technology named tandem bomb has been developed for intercepting the ERA. In essence, a tandem bomb weapon is an explosive device or flying object that has two or more explosion stages. This tandem bomb weapon is effective against reactive armor designed to protect armored vehicles (mainly tanks) from anti-tank bombs.

  The tandem bomb has two or more explosion stages. The first explosion phase of the tandem bomb weapon is typically a glaze that is weak enough to trigger the ERA in the event of a collision in order to allow the second warhead to pass unhindered. In general, this is intended to detonate the reactive armor before the main propellant arrives, so that the timing of the intercept explosion does not destroy the main explosive that comes to the second explosive stage. The second explosion stage of the tandem bomb targets the same location as the first explosion location. This is a blind spot in reactive armor. The reactive armor is the primary weapon of an armored vehicle to withstand the impact of the HEAT jet, so if the reactive armor is disabled in the first explosion stage, the main glaze (for second explosion) Increases the possibility of penetrating the main armor of the vehicle.

  Accordingly, it is an object of the present invention to provide a reactive armor module that can intercept a tandem warhead.

  The reactive armor according to the present embodiment is located in the vicinity of the reactive armor module including the first trigger screen and the explosive layer, and is connected to the first trigger screen for detonation. And at least one explosive module.

  Regardless of whether or not an explosive module is used, the reactive armor module can have a shaped glaze to generate a directional wavefront, and the trigger screen can be divided into at least two trigger parts; Each triggering part is triggered by a different approach angle of the flying projectile and can cause an explosion at a different part of the reactive armor module or in the case of having another explosive module.

  FIG. 1 shows a schematic structure of a HEAT shaped glaze tandem warhead 10. The warhead 10 includes a tip 11, a first (first) glaze 12, a first stage fuze 13, a spacing bar 14, a main glaze 15, and a second (main glaze) fuze 16.

  As described above, when colliding with general reactive armor, the first glaze of the tandem warhead explodes to produce a first jet, which activates the reactive armor glaze. Thereafter, at a predetermined precise timing, the second glaze of the tandem warhead explodes causing a second jet, which is the location previously actuated by the first glaze in the reaction module. From the vehicle body armor.

  FIG. 2 shows a cross section of a typical reactive armor module 20. The reactive armor module 20 has a front plate 21, a back plate 22, and a high-performance glaze 23 between the two plates. As mentioned above, the remarkable effectiveness of the reactive armor is mainly due to two basic mechanisms. First, the moving plate changes the effective speed and angle of the shaped glaze when the jet collides, and changes the incident angle of the jet to lower the concentration of the jet. Second, because the plate is also angled with respect to the typical collision direction of the shaped glaze warhead, and the plate moves outward, the collision point on the moving plate is As the time changes, the jet needs to cut a new plate part of the plate, effectively increasing the effective plate thickness upon landing.

  Typical reactive armor has been shown to be very effective at intercepting single stage rocket-propelled HEAT shaped glaze warheads such as RPG7, TOW, LOW, however, tandem warheads such as RPG-29 I can't intercept.

  FIG. 3 is a cross-sectional view illustrating the structure of the reactive armor module 30 according to an embodiment of the present invention. The reactive armor 30 can be a stand-alone module or can be an additional module of an existing reactive armor module. In the latter case, the reactive armor 30 can be placed in front of a typical reactive armor module (20 in FIG. 2) or behind the module 20. In certain embodiments, a space can be provided between the module 30 and the module 20.

  The module 30 of the present invention has a front plate 31 and a back plate 32. In one embodiment, the plate is made of any rigid material, such as steel, ballistic aluminum, titanium, alumina, or a composite of the materials. In another embodiment, plates 31 and 32 are made of a polymer or material with similar properties, such as Dynema, Spectra, Aramid. In another embodiment, the plates 31 and 32 can be made of a combination of polymer and rigid material. In yet another embodiment, the front plate 31 and the back plate 32 can each be made of different materials or combinations of different materials.

  The module 30 further has two inner layers between the front plate 31 and the back plate 32. The first layer of the two inner layers is a particle layer 33, and the second layer of the two inner layers is a high-performance explosive layer 34.

  The particle layer 33 includes a plurality of rigid particles. For example, the rigid particles have a specially designed shape that ensures collision with a spherical, cylindrical, or flying tandem warhead and maximizes the possibility of confirming penetration into the tandem warhead. be able to. In some embodiments, a combination of various shapes can be used.

Also, as shown in the inset, the particles 3311 can have an iron core 3312 surrounded by a layer of lightweight material 3313 and an outer shell 3314. As a result, the particles 3311 are separated from each other and do not interfere with each other when the explosive layer 34 explodes.

  FIG. 4 is a schematic diagram illustrating a method of operating the reaction module 30 according to some embodiments of the present invention. Two reactive armor plates 30 and 20 are placed one in front of the other. When the tandem warhead 50 collides with the front plate 31 of the reactive armor plate 30 on the front, the first fuze of the tandem warhead causes an explosion, creating a jet that breaks through the front plate. When the jet breaks through the particle layer 33, the jet eventually collides with the high explosive layer 34, causing the explosion of the explosive layer, which explodes the particles into the main (second) glaze of the tandem warhead 50. Ejected toward. These particles are ejected towards the flying second part of the tandem warhead and collide with this second part at a very high speed before an explosion of the second part of the second warhead is triggered. . The collision of the metal particles traveling at ultra-high speed damages the intact state of the second part of the tandem warhead and significantly impairs the ability of the tandem warhead to combine and form a concentrated jet. In some cases, if a large number of particles hit the second part, the second part may be completely useless even if the main part of the second part cannot be exploded. There is.

  As will be described in more detail hereinafter, the reactive armor layer 30 may include a trigger screen that allows control of the timing of the explosion.

  In one embodiment, the particles can be spaced apart to reduce kinetic energy exchange between the particles caused by the mechanical impact caused by the jet. The spacing between the particles can be achieved by coating each particle with a soft material, such as aluminum, polymer, or energy absorbing expansion material. This has been described above with reference to FIG. Alternatively, an energy absorbing element may be between the particles. In yet another alternative, the high performance glaze can be mixed between the particles. In yet another embodiment, in addition to mixing glaze between the particles, a back layer of high performance glaze is provided. In another embodiment, an additional explosive layer can be provided between the particle layer and the front plate. In another embodiment, in order to prevent damage to the high explosive layer due to the kinetic impact of the jet on the metal particles that may damage the glaze, the particles and the high explosive layer There can be a layer of rigid or composite material between.

  In another embodiment, the cross-sectional structure of the casing is designed to induce the energy of the explosion to produce the desired particle cloud vector and shape. For example, the high-performance explosive is molded into a curved shape or placed in an inclined or curved casing. Some examples are shown below. In yet another alternative, a rigid material can be placed over a portion of the shaped explosive, causing a time differential explosion between the scattered particles. In another aspect, a geometric element such as a pyramidal element is inserted between the particles with its tip facing the explosive layer so that the blast effect is imparted to the particle vector upon explosion.

  The reaction module 30 according to the embodiment of the present invention may have an additional front layer in front of the front plate 31. Such an additional front layer activates the reactive armor module either on an electronic signal or on a continuous blast caused by explosives mounted on the additional plate upon impact with the tandem warhead. It can be used as a triggering mechanism.

  In another embodiment, a proximity fuze or proximity sensor can be coupled with one or more reactive armor modules 30 to activate an explosion before the tandem warhead collides with the faceplate.

  FIG. 5 shows a schematic structure of a reaction module according to still another embodiment. Contrary to the previous embodiment, the reaction module of FIG. 5 is designed to take advantage of the well-known effect of implosion in the art, wherein the blast of the reaction module is directed to an incoming HEAT jet, The wave of the blast is directed into a body made of rigid particles arranged in a predetermined structure, and the structure is internally collapsed, and the rigid particles forming the structure dynamically change the relative positions of each other. Sometimes, the incoming jet is deformed by applying a multi-directional impact to the incoming jet many times and causing the incoming jet to interact with the moving rigid particles many times. At this time, the angle, velocity, surface, and the like at the time of collision of each rigid particle affect the HEAT jet not only when the rigid particle is formed but also in the initial penetration stage of the HEAT jet. Furthermore, even after the initial collision, the rigid particles continue their collapsing action due to the residual explosion energy of the implosion, so that the collision of the HEAT jet with the tail continues. The reaction module 130 includes a front plate 131, a back plate 132, a front explosive layer 134 attached to the rear surface of the front plate 131, and a particle layer 133. The explosive layer 134 of the present embodiment covers almost the entire area of the rear surface of the front plate 131. Upon impact by the HEAT glaze, the explosive layer 134 is detonated, causing an explosion that self-collapses the structure of the rigid particles, imploding as described above, and the rigid particles are in multiple directions from the HEAT jet. Effectively damaging the jet and causing the jet to collapse.

  FIG. 6 illustrates yet another embodiment of the reaction module 130 according to one embodiment of the present invention. The reaction module 130 includes a front plate 131, a back plate 132, a front explosive layer 134 attached to the rear surface of the front plate 131, and a particle layer 133. The explosive layer 134 of the present embodiment covers substantially the entire area of the rear surface of the front plate 131, and has an extension 141 along the side plate of the reaction module. Upon the collision of the HEAT glaze, the explosive layer is activated to cause an explosion that releases the rigid particles along the explosion wave. When the explosion wave emerges from the asymmetric geometry of the explosion layer, the locus of the explosion wave is not clear. Rather, the explosive waves emanating from each surface move the particles in one or more directions, applying a number of mechanical forces to the flying HEAT jet, effectively collapsing the jet. Optionally, the explosive geometry can be varied to create a large number of shock centers, and the particles can be ejected from a number of directions such that the particles add significant kinetic energy to the jet, Effectively destroy the jet. Further, the focal point of the shock wave generated by the explosion is directed and / or shaped by shaping the explosive geometry to produce a directional explosion wave in a manner known in the art as the Monroe effect. Or can be strengthened. Firing the particles towards a collision course with the HEAT jet or a collision course with other particles that will eventually give the particle a secondary impact that will affect the HEAT jet Thus, the blast lens 140 is formed in a shape that directs and amplifies the shock wave in a given direction. In one embodiment, some parts of the blast are focused by the blast lens, while other parts are not. This effect can be enhanced by inserting a liner into the blast lens 140. In another embodiment, the action of the blast lens can guide the trajectory of the rigid particles to a desired course and disperse the shock wave.

  FIG. 7 shows yet another embodiment of the present invention. The extension 141 of the explosive layer in FIG. 6 completely covers one side surface, whereas the extension 141a covers only a part of the surface. Furthermore, in the embodiment of FIG. 6, there is only one extension 141, but the embodiment of FIG. 7 has a second extension 141 b, which in this example is the reactive Arranged on the opposite corner of the armor module 130. The extension 141b can cover the entire side surface. Preferably, the two extensions 141a and 141b are arranged on different axes as shown. Upon receiving the impact of the HEAT glaze, the explosive layer is detonated to cause an explosion that causes the rigid particles to be fired along the explosion wave. Since the explosion wave has a plurality of centers (as an effect of the asymmetric geometry of the explosive layer in this embodiment), the explosion wave from each surface at the time of the collision that causes the flying HEAT jet to explode the glaze 134 Can move the particles continuously in multiple directions. Since the explosion point can be close to either the extension 141a or the extension 141b, the explosion can reach one of the extensions earlier than the other. Different types of explosives can be used for the extensions 141a and 141b to ensure that the explosion occurs non-simultaneously. Furthermore, the two extensions do not face each other in a strict straight line in order to prevent a reduction in the blast yield effect. In another embodiment, the rigid particles adjacent side surfaces 141a and 141b each have one or more of different masses, different shapes, and different alignment structures. Furthermore, the particles can be embedded in multiple materials of different densities, different particle arrangements, and different tensile strengths.

  Numerous mechanical forces generated by the asymmetric structure effectively collapse the jet. Also in this embodiment, similar to FIG. 6, the geometry of the explosive can be varied to create a number of shock wave centers, which allows the particles to enter the jet from more than one direction. The particles can be fired to effectively break the jet, which adds high kinetic energy. Further, the focal point of the shock wave generated by the explosion is oriented and / or shaped by shaping the explosive geometry to produce a directional explosion wave in a manner known in the art as the Monroe effect. Or can be strengthened. The blast lens 140 (shown in FIG. 6) is configured to shape, direct and amplify the shock wave in a given direction and to collide with the HEAT jet, or ultimately the One or more of the explosive layers to fire the particles towards a collision course with other particles that will impact the particles with a secondary impact that will affect the HEAT jet. Can be incorporated into the place. This effect can be enhanced by inserting a liner into the blast lens 140. In an alternative embodiment, the function of the blast lens can be altered to disperse the shock wave to produce a trajectory of the rigid particles to the desired course.

  FIG. 8 illustrates a three-layer reaction module according to yet another embodiment of the present invention. It will be readily appreciated that the three layers are merely examples, and that additional embodiments can be added to form other embodiments. The reactive module 230 includes a strike surface, rear surfaces 231 and 232, a first explosive layer 234, a second explosive layer 235, a third explosive layer 236, and a fourth explosive layer 237. The first steel wall 246 has openings 246a, 246b, and 246c, and is disposed between the first explosive layer 234 and the second explosive layer 235, and separates the first explosive layer 234 and the second explosive layer 235. To do. The explosive layers 234, 235, 236, and 237 can be composed of a single relatively fast explosive material. A first particle and explosive structure 233 a is disposed between the strike surface and the first steel wall 246, and a second particle and explosive structure 233 b is disposed behind the steel wall 246. The separator 239 separates the second particle and explosive structure 233b from the third particle and explosive structure 233c. The structure 233a can be composed of an explosive that reacts slower than the explosives in the explosive layers 234-237. The structure 233b can be composed of an explosive that reacts more slowly. Structure 233c can be composed of an explosive that reacts slower than explosives of all other structures. Upon impact with the HEAT jet, the explosive layer 234 explodes and ejects rigid particles in various directions, thereby destroying the main propellant of the flying warhead.

  The evolution of the explosion between the layers is not clearly determined and several evolution paths are possible. For example, when the explosion begins in the first particle structure 233a, the blast propagates through the opening 246 and activates the second main explosive layer 235, causing an immediate explosion of the second explosive layer 235. When the second explosive layer 235 explodes, the implosion process detailed above begins in the particle structure 233b and the particle structure 233b self-collapses. Following this explosion, the blast propagates through the explosive layer 236 and activates the explosive sequence of the explosive layer 237. The explosion of the explosive layer 237 causes an internal collapse of the particle structure 233c, and at this time, the particles of the particle structure 233c collide with the particle structure 233b that has collapsed. The multiple occurrences of implosion due to the multiple explosion structures effectively collapse the flying HEAT jet. More specifically, the many mechanical vectors created by the asymmetric arrangement effectively collapse the jet.

  Also, in this embodiment, as in FIG. 6, the explosive geometry can be changed to create multiple shock wave centers, thereby ejecting the particles and moving the particles from more than one direction. A large kinetic energy can be applied to the jet to effectively destroy the jet. In addition, by shaping the explosive by creating the explosive geometry in a manner well known in the art as the Monroe effect, the focus of the shock wave produced by the explosion is reduced. Orientation and / or amplification can be performed. The blast lens 140 (shown in FIG. 6) is configured to shape, direct and amplify the shock wave in a given direction and to collide with the HEAT jet, or ultimately the One or more of the explosive layers to fire the particles towards a collision course with other particles that will impact the particles with a secondary impact that will affect the HEAT jet. Can be incorporated into the place. This effect can be enhanced by inserting a liner into the blast lens 140. In an alternative embodiment, the function of the blast lens can be altered to disperse the shock wave to produce a trajectory of the rigid particles to the desired course. It will be readily appreciated that including the opening in the steel sheet or separator is optional.

  This example is non-limiting. The reason is that additional separators, lenses, or steel plates can be used to shield one or more explosive layers, thereby preventing premature explosive collapse. is there. Furthermore, in order to reinforce the steel plate, as described above, materials such as alumina 98 and silicon carbide may be used as a part of the reaction module, and a plurality of various materials such as polymers or various kinds may be used. Direct, strengthen, weaken blast-induced forces and physical and mechanical effects that may affect the final results of the module, as described above, etc. Also note that it can be used for: Note that the use of the reaction module of the present invention can be carried out as a stand-alone module or in combination with other modules, ie the modules described herein or modules known from the prior art. I want to have it.

  It will be readily apparent that the typical reactive armor is generally implemented obliquely with respect to the vertical direction (this condition is also not shown schematically in FIGS. 2 and 4). .

  In another embodiment of the present invention, a trigger screen is provided to allow time controlled activation of the blast sequence within the ERA of the present invention. Trigger screens are well known in the art. For example, the trigger screen shown in FIG. 9, model number PT-0303500600MK, is manufactured by Whisner Corporation (American company). Trigger screens are commonly used to close electrical circuits when the trigger screen is penetrated. Upon penetration into the trigger screen, the electrical circuit is closed and the detonation circuit is activated, causing the glaze to explode. The trigger screen can alternatively be made by a piezo element. This piezo element is an element that generates a current when pressure is generated due to an explosion event. Or the detonator can be activated by detection of an electromagnetic field. It should be understood that every location of the specification referring to a trigger screen includes other means of performing blast timing control or blast sequence control.

  The delay time of the blast sequence can be controlled by means known in the art, for example, allowing the blast sequence to start 5-20 microseconds from the trigger screen penetration time. The distance from the explosive layer 134 or other part of the glaze that is considered important to the trigger screen is a large factor that allows control to cause the explosion to occur before it is impacted by the jet. As shown in FIGS. 9 to 9C, the trigger screen 241 is used for time control of the blast of the high explosive layer 134. According to embodiments of the present invention, this type of trigger screen 241 is mounted at the rear of the strike surface. The distance from the explosive layer 134 to the trigger screen 241 determines the maximum time before a blast sequence can be initiated in the glaze before the jet strikes an element in the ERA of FIG. 9B. Can be adjusted. In FIG. 9C, the screen is disposed, for example, in an element constituting the glaze. As the jet passes through the elements that make up the glaze, the glaze initiates a blast sequence before the jet jumps to a set point in the glaze.

  This type of technology triggers the prior art ERA module 20 (see FIG. 2) to explode the ERA module 20 before the shaped glaze jet hits the front steel plate sandwiching the high-performance explosive. It will be readily apparent that can also be used. It will also be readily appreciated that utilizing the trigger mechanism using a trigger screen 241 (shown in FIG. 9A) can dramatically increase the likelihood that the ERA module of FIG. 2 will intercept the jet. 9A, 9B, and 9C show a screen 241 disposed at a predetermined distance in front of the front plate 21 of the ERA 20. The detonator is shown as numeral 243 in FIGS. 9A, 9B, and 9C. The explosion circuit is a regular product and is not shown in the above figure for the sake of brevity.

The extensions 141a and 141b, coupled with the overall distribution of the explosives, ensure a high degree of destructiveness of the explosion wavefront.

  FIG. 9C shows a cross-sectional shape of the reactive armor module obtained by adding the trigger screen of the present embodiment to the reactive armor module shown in FIG. The trigger screen 241 is disposed in the space 2412 behind the strike surface 2410 by a predetermined distance. The space 2412 has a predetermined size, is disposed between the strike plate 2410 and the front steel plate 246, and includes the first explosive layer 233a. The front steel plate 246 has a plurality of openings 246a, 246b, and 246c, and is disposed in front of the explosive layers 233b and 233c. The explosive layer 233c is similarly disposed in front of the rear steel plate 22.

  The space 2412 may be any size. As described above, the screen 241 is connected to the detonator 243 and the distance between them is the explosive layers 233a, 233b and 233c after the trigger screen is activated in order to generate a destructive wavefront.

  This will be described with reference to FIG. 9D. FIG. 9D shows that the particles in FIG. 9B are replaced with a stack of multiple steel layers. Each steel layer is behind an explosive layer. Two glazes on both sides of the module are exploded, causing a scissor effect.

FIG. 10 discloses another embodiment of the present invention. In the present embodiment, the explosive layer 234 is formed or molded so as to be somewhat inclined with respect to either a horizontal plane or a vertical plane. In the configuration of the reactive armor glaze, upon explosion, the particle structure 233 is launched toward the incoming HEAT jet while applying an oblique shear force to the jet 277 that is about to collide with the particle structure 233. The In another embodiment shown in FIG. 11, the reactive armor activates the blast sequence via wire 278 in addition to the tilted explosive layer 234, resulting in detonator 243 as described above. It has a trigger screen 241 for detonation. The trigger screen can be used as a means for closing an electrical circuit to generate an electromagnetic signal or a radio frequency (RF) signal. The signal is received by a suitable receiver and then initiates a blast sequence that can activate the detonator 243.
In yet another embodiment, a trigger screen, or other device that can initiate the blast sequence can be connected to one or more reactive armor modules. Alternatively, as described with reference to FIG. 9, the trigger screen can be split and different trigger sequences can be executed in the reactive armor unit depending on the direction of the flying object.

These means can replace the trigger screen and can release the power necessary to trigger the blast sequence in the event of a collision. Preferably, the elements (b), (e) and (f) should be placed some distance in front of the glaze.

  FIG. 12 shows a reactive armor that includes two steel plates 160 and 161 sandwiching a high explosive layer 162. The high-performance glaze has a detonator 163 that is actuated by a trigger screen, which is drawn in the upper part of FIG. When penetrating the trigger screen, an explosion is triggered by the trigger screen mechanism before the contact with the high-performance explosive 162 sandwiched between the steel plates 160 and 161 begins, and the high-performance explosive explodes. Before the incoming jet 165 collides with the reactive armor sandwich, one or more metal plates are ejected towards the incoming jet. The trigger screen is behind a strike surface 166 to prevent accidental actuation by elements different from the HEAT jet. The explosive layer has a certain angle with respect to the strike surface, and the point concentration of the flying jet can be reduced by an explosion having a certain angle with respect to the flying jet.

  The battery 167 can supply power for operating the detonator 163.

  It will be readily appreciated that the strike surface 166 of all or any of the reactive armor modules described above can be constructed from rigid metal elements such as steel, titanium, ballistic aluminum, any type of metal alloy. Furthermore, the strike surface can be made of a rigid material such as alumina or boron carbide. Furthermore, the strike surface can be composed of various polymers such as aramid and dynema. Furthermore, the strike surface can be composed of a compressed fiber such as glass or carbon fiber. Each or any of the above materials can be combined or replaced with the strike surface shown in the drawing as steel. The same applies to all other layers shown herein as steel layers.

  FIG. 13 shows yet another embodiment of the present invention. The same parts as those in FIG. 12 are denoted by the same reference numerals, and description thereof will be omitted unless necessary for understanding the present embodiment. The explosive layer 170 includes one or more shaped glaze lenses 171 designed to generate a wavefront that collapses the flying jet 165. The lens may or may not include a liner 172 (well known in the art). The liner can be copper or similar material so as not to absorb too much energy of the explosion. The explosive lens can be provided in various configurations, such as configurations 173 and 174 that are directed to impacts in different directions. A reactive armor module created using the explosive lens can be used to intercept the incoming HEAT jet 165 by activating the lens using the trigger screen 164. In one embodiment, different parts of the module have differently shaped lenses. In yet another embodiment, the different portions of the module are actuated by different portions of the trigger screen so that impacts from different directions collide with appropriately directed explosion waves.

  In order to direct the blast in a more suitable direction, the cross-sectional shape of the lens can be triangular (shown in the figure), spherical, or any other shape. In another embodiment, the lens may be a partially spherical shape having a plurality of grooves or holes. The groove can be filled with a liner. The groove or hole can enhance the effect of the lens by concentrating force.

  FIG. 14 shows a combination of the particle-based explosive reactive armor module 720 and the explosive reactive armor module 721 described in FIG. The same parts as those in FIG. 12 are denoted by the same reference numerals as those in FIG. 12, and will not be described again unless necessary for understanding the present embodiment. Each of the reactive armor modules 720 and 721 is provided with a trigger screen 164. Either of the two trigger screens can activate the reactive module in a time-controlled blast sequence. The incoming tandem projectile 722 generates an initial jet 723. The initial jet triggers the screen 164 of the first module 720, and the resulting explosion forms a particle cloud 724 that causes the larger jet of the main explosion of the flying object 722 to disappear. Module 721 is still not triggered. However, it is triggered when the flying object 722 lands beyond the module 720. Alternatively, the module 721 remains in the intercepting position at the same location in preparation for another tandem projectile attack.

  In all embodiments herein, a plurality of the modules can operate continuously in a tandem configuration, for example, a plurality of the modules can have one module in front of another module, or , One module placed next to another or in a cluster configuration of several reactive armor modules. Each module can have its own trigger mechanism as described above, or can be triggered by a single trigger mechanism. A trigger screen coupled to one reactive armor module can act in conjunction as described above, upon activation, initiating a blast sequence in the other module.

  In yet another embodiment, a plurality of reactive armor modules described in this application, or known in the art, are arranged in series to increase the likelihood of the HEAT jet annihilating or greatly deforming. I.e. placing one module in front of another module, placing one module on top of another module, placing one module next to another module, etc. Start by controlling the time interval. One or more reactive armor modules known in the art include explosive reactive armor, non-automatic reactive armor, and the like. An explosive reactive armor module 900 including a steel layer 901, a high explosive layer 902, and a steel layer 903, shown in the non-limiting example of FIG. 15A, is placed in front of the module of FIG. 15B. In a non-limiting example, module 920 of FIG. 15B includes trigger screen 921, steel layer 922, high explosive layer 923, detonator 924, energy source 925, wiring 926, as described in detail in this application. And a steel layer 927. FIG. 15C shows the combined configuration 930 with the reactive module 900 of FIG. 15A and the reactive module 920 of FIG. 15B with fillers 952, 953, and 954 interposed therebetween.

  The filler is used to support the reactive module in a common casing and / or allows the steel sheets of modules 900 and 920 to be decelerated or accelerated, and further to maintain dissipated residual explosion energy. to enable. The filler may be made of different density polymers such as high density foamed polystyrene, low density foamed polystyrene, or any material that can be shaped to provide mechanical support. The mechanical support may include altering the areal density by inserting voids into the material and / or building a mechanical structure capable of supporting weight such as a honeycomb structure, Such an energy absorbing material is inserted into the arbitrary material, or a fluid such as water is contained in the containers disposed in the holes 952, 953, and 954. Furthermore, the filler can be made of a composite material containing metals having different areal densities in the same manner as the production by gas pumping in order to produce a rigid material based on polystyrene foam or the like. Further, by using different mass steel plates in each of the modules 900 and 920, the interaction between the residual effects of the module explosion follows a predetermined collision pattern between the explosion wave and the steel element. Can be modified as follows.

  For example, if the steel plates 922 and 927 of the module 920 have different masses, the steel plates will fly in the opposite direction and / or at different speeds as well as interact with the residual effects of the explosion To the extent it can hit the HEAT jet at higher or lower speeds. Upon impact, the tip of the HEAT jet 940 causes the modules 900 and 920 to explode. The following parameters are adjusted to optimize the overall efficiency of module 930. (A) distance between modules 900 and 920, (b) relative angle between modules 900 and 920, (c) material and mechanical properties of fillers 952, 953 and 954, (d) used. Technical characteristics of high-performance explosives, their weight (density per module), and technical advantages of using different explosives with different masses in each of modules 900 and 920, (e) detonator technology Characteristics, or technical advantages of placing multiple detonators in a single module as shown in FIG. 15D, (f) of explosive wiring when using explosive wiring to enable explosion initiation Characteristic.

  The technical features of the explosive include the explosive speed of the explosive. For example, layer 900 can be the slowest layer. Layer 920 can be a faster layer and can be activated using, for example, a trigger screen. A third layer can be added forward in the direction of the flying object, and the added layer can be actuated by a trigger screen with a very fast layer. Other suitable combinations may be used. Although FIG. 15B uses a single initiator 924, FIG. 15D shows an embodiment in which several initiators are used in the module 920. More specifically, FIG. 15D shows a top view of an array of detonators 924A-924N. When a detonator, such as detonator 924 in FIG. 15B, is activated, a set amount of time elapses from the start of the explosion until the entire mass of the high-performance explosive is consumed. In order to minimize and speed up the entire mass of the high-performance explosive mass 923 (FIG. 15B), the plurality of detonators are dispersed in the high-performance explosive to cause a more uniform explosion. Can be operated at the same time. Alternatively, a detonator directed in a specific direction can be provided for the sequential explosion. The use of multiple detonators as described above can be applied to all of the various embodiments of the present invention.

  The energy applied by the HEAT jet to the steel plate is such that even if the steel is replaced with a metal alloy such as titanium, there is almost no difference in the overall performance of the reactive module as shown in FIG. 15A. Steel is used for reactive armor modules. That is, the same thickness is required. In the embodiment of the invention as shown in FIG. 15B, the steel can be replaced with low density materials such as titanium and aluminum alloys. When ballistic aluminum and titanium alloy are used, a large amount of members are fired toward the flying HEAT jet, so that significant performance improvement can be realized. The interaction between the high speed thicker moving plate and the flying jet has proven to be very efficient, and the equivalent mass of titanium fired against the flying HEAT jet is the steel of the jet. The efficiency of preventing penetration of the target is 250% higher compared to reactive armor modules using the same mass of steel. Further, when the reaction module of FIG. 15A and the reaction module of FIG. 15B are compared using the same amount of high-performance explosive, ballistic aluminum, and titanium alloy, when using ballistic aluminum and titanium alloy, the jet A very good performance (150%) was obtained in terms of preventing the penetration of the steel target with 150% efficiency.
