Description

INSTALLING STRUCTURE OF AN EXPLOSIVE REACTIVE ARMOR FOR COMBAT VEHICLE}

The present invention relates to a mounting structure of the combat vehicle reaction gloves, and more particularly, to increase the mounting strength of the reaction gloves mounted on the combat vehicle, and also to combat vehicle response that can minimize the accompanying losses of the reaction gloves during operation The mounting structure of the glove.

In general, reaction gloves are mounted on the outer surfaces of combat vehicles such as tanks and armored vehicles, and react when fired by threats such as enemy fire pellets or kinetic energy bombs, thereby protecting the vehicle. As a glove part, it is divided into explosive reaction gloves and non-explosive reaction gloves according to the operation method.

Among these, the explosive reaction gloves were first developed in Israel and applied the blazers to the tanks for the first invasion of Lebanon in the world for the first time in the world, and after that, Russia's KONTAKT, UK's ROMOR and As reaction gloves such as BRENUS of France are developed in earnest, reaction gloves are attached to combat vehicles in order to maximize combat power in many countries such as USA, Poland, China, Slovakia and North Korea.

1 and 2 illustrate an example of an explosive reaction gloves widely used in Russian T-series tanks. As shown in Figure 1 and 2, the configuration of the explosion-type reaction gloves 100 is attached to the attachment piece 112 having the bolt fasteners 111 on both sides to be attached to the outer surface of the combat vehicle (T) by bolts. A block body 110 having a case shape, a reaction element 120 accommodated in the internal space of the block body 110, and a block sealing the lower portion of the block body 110 so that the reaction element 120 is not separated from the block body 110. It consists of a sieve cover (130).

Here, as shown in FIG. 3, the reaction element 120 has a structure in which a reaction material 121 is filled and sealed between two steel sheets 122 having excellent ballistic resistance. The reactant 121 is a composite explosive stabilized by adding a stabilizer, a binder, and a plasticizer to a variety of explosives (TNT, RDX, etc.), and is filled in a box form as shown in FIG. One or more reaction gloves may be charged, depending on the required performance.

The reaction gloves 100 configured as described above, when the threat bomb collides with the outer surface of the reaction gloves 100 attached to the combat vehicle T, penetrates the block body 110 of the reaction gloves 100 to the reaction element 120. When the impact is applied, the reaction material 121 between the two steel plates of the reaction element 120 causes an internal explosion. By the explosive force, the two steel plates are scattered in the forward and reverse directions of the penetrator (long penetrator or molded peony jet), respectively, to impede or deflect the penetrator, thereby weakening the penetrating force to the combat vehicle T. It has the effect of protecting a combat vehicle (T).

As described above, since the reaction gloves 100 are simply mounted on the combat vehicle T by bolts, the mounting method has a simple advantage. However, since the attachment pieces 112 having the bolt fasteners 111 on both sides of the block body 100 protrude in the horizontal direction so as to be attached to the outer surface of the combat vehicle T by bolts, the attachment pieces 112 are provided. Due to this, there are many gaps between the reaction gloves and other adjacent reaction gloves, and thus there is a disadvantage in that there are vulnerable areas from the threat bomb in the combat vehicle T.

In order to make up for these shortcomings, US combat vehicles produced a mounting structure of the reaction gloves as shown in FIGS. 4 and 5 separately, and then assembled the mounting structure to the combat vehicle first, and then presented a method of mounting the reaction gloves. There is a bar.

First, FIG. 4 is repeated to the flat portion 211 and the inclined portion 212 to mount the reaction gloves in the module unit in the front portion of the combat vehicle (T) and has a bolted hole in the flat portion 211 In the installation of two separate mounting portions 210 in the combat vehicle T at regular intervals, after assembling the flat parts contacting the outer surface of the combat vehicle T with the combat vehicle T by bolts, the reaction gloves Shows a method of mounting the bolt to the flat portion away from the outer surface of the combat vehicle (T).

FIG. 5 shows that two vertical guide rails 310 are welded or bolted to the side surface of the combat vehicle T at regular intervals in order to mount the reaction gloves in the module unit on the side surface of the combat vehicle T. After assembling, the guide part 301 formed in the vertical direction along both edges of the reaction gloves is inserted into the vertical guide rail part 310 in a sliding manner and mounted.

As described above, in the method of mounting the reaction gloves shown in FIGS. 4 and 5, unlike the method of mounting the reaction gloves illustrated in FIGS. 1 and 2, the reaction gloves modules may be densely mounted with almost no space between the reaction gloves modules. There is almost no weak spot in combat vehicle equipped with reaction gloves.

However, this mounting method has a disadvantage in that the weight increase and the rigidity of the mounting are somewhat lowered because a separate mounting structure is used instead of directly mounting the combat vehicle.

On the other hand, explosive reaction gloves are generally manufactured in modular units to facilitate individual installation and replacement. The explosive reaction gloves are mounted on the combat vehicle in a manner that collectively arranges the reaction gloves modules on the weak parts of the combat vehicle.

Thus, the explosive reaction gloves are ideally suited for the individual modules mounted independently of the threat and only the activated response module itself is lost, but some of the surrounding reaction gloves modules are inevitably dislodged by the explosion impact. Result in damage to the product. The accompanying loss of the surrounding reaction gloves has a problem that the combat vehicle is very vulnerable to subsequent attacks.

Accordingly, the present invention has been made in view of the above-mentioned conventional problems, and increases the mounting strength of the reaction gloves mounted on the combat vehicle, and also mounts the reaction gloves for combat vehicle that can minimize the accompanying loss of the reaction gloves during operation. The purpose is to provide a structure.

In order to achieve the above object, the present invention includes a case-shaped block body mounted on the outer surface of the combat vehicle, and a reaction element that is received in the inner space of the block body and sealed by a block body cover covering the upper opening of the block body.
