Description

D REAL MOUNTED ARMOR OF AN ARMOR CAP A utility model relates to the field of armor structures, and specifically to mounted reactive armor and can be used in armor protection structures of armored objects. Known .dynamic protection .for MBOA tanks of the United States Marine Corps (see Journal $ z / wz 1990, Volume 99, No. 2, pp. 16-17 Gleg article, Mr. Ј Mairfe / laid. О # 60А1 $) Mounted reactive armor in the form of elements with explosives, bolts attached to spacers, which are also bolted to bonks. Bonkas are welded to a tower. The disadvantage of this design is that this reactive armor resists only the effects of rocket-propelled grenades, but does not provide protection against cumulative and sub-caliber shells. Known reactive tank armor Blazer (see 3cine s e-fence W & tk & j1985, No. 19, p. U49-U50), providing a one-time protection against anti-tank missiles and anti-tank grenades. Armor is mounted on tanks outside. It consists of modular protective elements, each of which contains inserts filled with explosives. When an anti-tank projectile enters the tank and ignites its cumulative charge, the element liner is undermined, which significantly weakens the cumulative effect of the projectile. The disadvantage of this design is that it does not protect the tank from modern sub-caliber shells. A well-known tank tower (see patent of Germany No. 978036, I976, F 41 N 5/02), on the surface of which mounted hinged armor panels, on the front surface of which are installed protective charges re 41 F 5/007

active armor, connected via means of initiating an explosion with projectile sensors (see Fig. 6.9 of this patent).

The disadvantage of the tower is the unreliable fastening of the armor panels when exposed to attacking tanks ... shells and ATGMs. In addition, arising large shock loads when triggered by its protective charges lead to the breakage of armor plates.

The purpose of the utility model is to increase the reliability of mounting armored units, with reactive armor on the armored cap.

This goal is achieved due to the fact that on the outer surface of the frontal wall of the armored cap there is a support. Arc-shaped belt for a horizontal horizontal groove in the back surface of the armored unit, and the frontal cylindrical wall of the armored cap and the cylindrical rear surface of the armored unit are made along a sector arc of 55f60 ° and a thickness equal to 0,, 25 of the thickness of the inner wall of the armored cap, while the inner wall of the armored unit is made with a thickness of 0,, 45 of the thickness of the inner wall of the armored cap, and the niche is flax width 3, Of3,1 the thickness of the inner wall of the armor cap.

The analysis of the main distinguishing features of the utility model and the beneficial effect obtained from them showed that:

a supporting arcuate belt made on an armored cap for a reciprocal horizontal groove on the rear surface of the armored unit, provides a weakening of the transverse loads of the bolt fastening of the armored units to the armored cap that occur during the actuation of the protective charge of reactive armor on the attacking shell;

the frontal cylindrical wall of the armored cap and the rear surface of the armored unit made cylindrical along an arc of a sector equal to provide optimal protection of the frontal part of the armored cap within the course angle;

- 2 thickness of the frontal wall of the armor cap made Q, 2fQ, 25 thickness of the inner wall of the armor cap provides the necessary conditions when the protective charge reactive armor;

the inner wall of the armored unit, made with a thickness of 0.4f 0.45 of the thickness of the inner wall of the armor cap, helps prevent its destruction when the protective charge is triggered and takes on part of the load of the protective charge;

a niche of the armored cap made of a width of 3, 1 of the thickness of the inner wall of the armored cap, and its frontal wall is made vertical, which allows the protective inserts to be installed as a single unit in one installation.

The utility model is illustrated by drawings, which show:

FIG. I is a plan view of a fragment of an armored cap with armored units hung on it;

FIG. Z - plan view of a fragment of an armored cap without

mounted armored units;

FIG. 3 - section aa of figure 1;

FIG. .4 - section AA of Fig. 1 without hinged armor blocks and a block of protective inserts.

The armor cap I contains an armored cylindrical frontal wall 2, conjugated with the side walls 3 (Fig.2,3). Niches 5 closed by covers 6 are made in the frontal part of the armored cap between the frontal 2 and the inner 4 walls. Protective inserts 7 are installed in the niches 5. Outside of the armored cap I, armor blocks 10 with cavities are installed using bolts 8 and threaded brackets 9 (Fig. 2), in which protective charge II is placed. The cavities of the armored blocks are closed by covers 12. On the day of increasing the reliability of fastening the armored blocks on the armored cap, on the outer surface of the frontal cylindrical wall 2 there is a support.

- 3 surfaces of the armored unit 10. The frontal cylindrical wall of the armor cap 2 and the cylindrical rear surface of the armored unit 2 are made along an arc of a sector with an angle (Ж- (see figure 2).

The thickness a of the frontal wall 2 (Fig. 4) is 0, 25 of the thickness in the inner senna 4. The wall thickness 4 corresponds to the thickness of the minimum inner wall of the armor cap. The inner wall of the armored unit 10 (Fig. 3) is made with a thickness of 0, 45 thickness in the inner wall 4. Niche 5 (Fig. 4) is made of width d. equal to 3,, 1 and the thickness of the inner wall 4.

Job

The assembly of the armored cap I is carried out as follows in a niche 5 (Figs. 2,3,4), a single block of inserts is installed 7. Then, the niche 5 is closed by a cover b, which is fixed, for example by welding, After this, the hinged armor block 10 (Figs. 1,3) having a reciprocal groove 14, a support cylindrical belt 13 of the front cylindrical wall 2 is brought in and attracted by bolts 8. When reflecting attack shells, reactive armor, and with it the thickness of the frontal wall 2 of the armor cap, is made within 0, 25 of the thickness of the inner wall 4 of the armor cap providing It has the necessary strength conditions when the protective charge of reactive armor II is triggered. Reducing these limits does not provide strength and survivability of the armored cap. An increase in these limits leads to an increase in the mass and dimensions of the tower and a deterioration in the technical and operational characteristics of the tank. The inner wall of the armor block wall Yu, made with a thickness of between 0, 45 thickness in the inner wall 4 of the armor cap, prevents its destruction when the protective charge is triggered and takes on part of the load of the protective charge, and a decrease in thickness can lead to destruction of the armor J% vw

block, and an increase - to increase the weight and dimensions of the armored cap. Niche 5, made ofr width of within 3,, 1 thickness in the inner wall 4, allows you to install protective inserts as a single unit in one installation, while expanding the niche 5 in its upper part does not increase the weight of the armored cap, because protective inserts are installed © by air gaps and have empty cavities, in addition, the expansion of a niche in the upper part increases the level of passive protection of the armor cap.

Thus, the armored unit mounted on the supporting cylindrical belt when undermining the protective charge allows you to redistribute the load on the power bolts, because lateral loads in this case are perceived as supporting :. a cylindrical belt, and longitudinal ones - with bolts, for which they are axial, i.e. the main loads are perceived by the supporting cylindrical belt, thereby weakening the effect on the bolt fastening of the armor blocks, thus the bolts work only in tension without perceiving shear loads.
