Abstract

Reactive armor of the object of protection, containing reactive armor blocks installed in the niches of the body of the object of protection and closed by the armor cover, each of which includes a protective charge with explosive, an armor plate and a buffer plate made of elastic material, characterized in that the protective charge is made in the form of a set identical in shape rectangular explosive packets laid layer-by-layer through a metal gasket in a niche with the overlapping of its entire rear surface, while the lower half of the packet layers is separated from the upper half of the packet layers by an armor plate, a buffer plate and a metal casing of the upper half of the packet layers, the lower and upper half of the packet layers being connected to each other through transfer metal tubes filled with explosive material, fixedly mounted in coaxial holes made in the armor plate, a buffer plate and casing.

Description

REACTIVE ARMOR OF THE OBJECT OF PROTECTION

The utility model relates to the field of armored structures, and specifically to reactive armor and can be used in the construction of buildings and towers of objects of armored vehicles.

Known reactive armor to protect enclosed surfaces from shells (see US patent 4981067, MKI5 R 41 H 5/007, NKI 89-36.17, published 01/01/91), containing two reactive plates, including the upper and lower inert layers having front and back flat surfaces. Between the layers is a layer of highly effective explosive mixture. Small holes are formed in the upper and lower inert layers to reduce weight.

A disadvantage of the known reactive armor is that it requires additional protection against random bullets and fragments.

Known reactive armor (see US patent 4867077, MKI F 41 H 5/04, NKI 109-36, published 09/19/89, or British application 2200437, P 41 N 5/04, NKI R ZS) containing an explosive mixture located between layers of elastic material, placed, in turn, between the armor plates and provided with side ribs for fixing the elastic bag with the formation of a closed protective unit that can be used to protect inclined reservation sheets of the vehicle.

A disadvantage of the known reactive armor is the lack of effectiveness in the defeat of the attacking shell.

jet armor

This goal is achieved due to the fact that the protective charge is made in the form of a set of rectangular shaped explosive packets of the same shape, laid in layers through a metal gasket in a beggar with the overlapping of its entire back surface, while the lower half of the packet layers is separated from the upper half of the packet layers by an armor plate , a buffer plate and a metal casing of the upper half of the packet layers, the lower and upper half of the packet layers are interconnected via metal-filled transfer materials skie tube fixedly mounted in the coaxial holes made in the armor plate, the buffer plate and the casing.

The analysis of the main distinguishing features of the utility model showed that:

the implementation of a protective charge with explosive in the form of two parts placed in tan.demno one after the other and connected between the transfer tubes with the explosive provides a more effective attack on the attacking shell;

the placement of the armor plate, the buffer plate between the two parts of the explosive also increased the effectiveness of reactive armor.

The utility model is illustrated by drawings, where:

FIG. I - shows a fragment of reactive armor (plan view) in the niche of the protected object, which shows the upper half of the explosive packages;

-fig, 2 - section aa. figure 1;

- in FIG. 2 - section BB of FIG. 1;

- and not), which shows the lower half of the explosive packages.

The reactive armor of the object of protection contains installed in the niches of the 1st building 2 of the object of protection and 3 reactive armor blocks closed by armor caps (Figs. 1-4). Each block includes a protective charge, made in the form of a set of identical-shaped rectangular packets of 4,5,6,7,8,9,10,11 explosives, layered in a niche I through a metal strip 12 with the entire rear surface of the niche overlapping 1, wherein the bags are divided in height into the upper part of the packet layers 4,5,6,7 and the lower part of the packet layers 8,9,10,11 by the armor plate 13, a buffer plate 14 of elastic elastic material laid on the plate 13, and bottom wall 15 of the metal casing, in which the upper layer of packets 4,5,6,7 with hney wall 16.

In the wall 16, in the plate 14 and the armor plate 13, coaxial holes are made in which metal transfer tubes 17 are mounted, welded to the plate 13 and filled with explosive 18.

Job

When a weapon hits the reactive armor of the object of protection, the following occurs. The shell penetrates the armor cap 3, the fragments generated in this case excite the 4,5,6 and u packets with explosives, which, detonating with the products of the explosion together with the cap 3, begin to act on the shell partially destroying it and changing the trajectory of movement. At the moment of undermining packages 4-7, the explosion energy is partially extinguished due to the buffer plate 14, preventing premature destruction of the armor plate 13 and deformation of the back wall of the niche I After undermining packages 4-7

-I detonation from them through the transfer tube 17 is transmitted to the packages 8-1I protective charge. Detonating elements 8-1I continue to act on the projectile with the products of the explosion, at the same time the armor plate 13, driven by the energy of the explosion of elements 8-1I, also affects the projectile.

Thus, the proposed utility model of the reactive armor of the object of protection has more effective protective qualities due to the multiple time-spaced multiple impacts on the lengthy core of the sub-caliber or cumulative stream of attacking shells, both products of undermining the protective charge and armor elements that are components of reactive armor.
