Description

EIOK WITH REACTIVE ARMOR OF DAY OF PROTECTION FOR (TORNOUS SURFACE FROM APPLIANCES

The utility model relates to the field of armored structures, and specifically to reactive armor and can be used to protect armored vehicles, for example, a tank.

Known reactive armor (see US patent IH867077, F 4IH 5/04, NKI 109-36, published 09/19/89, or British application No. 2200437, F 4IH 5/04, NKY EZS) containing an explosive located between the layers of elastic material, placed, in turn, between the armored plates and provided with side ribs for fixing the elastic bag with the formation of a closed protective unit, which can be used to protect inclined reservation sheets of the vehicle.

A disadvantage of the known reactive brooch is that when fastening the protective blocks end-to-end with their adjacent edges, the intermediate strip between the joints weakly resists small-caliber shells, letting them pass, and undermines both adjacent charges when a large-caliber projectile attacks, damaging adjacent blocks and the surface to be protected.

A known unit with reactive armor in order to protect the surface to be covered from shells (see no. 95121852 dated 12.26.95 with a positive decision of VNIIGPE from 02.28.97) containing armored plates and protective shutters installed between themselves at an acute angle, forming a space for placement the upper and lower rows of charges at an angle to each other with providing angles of meeting of the attacking shell, respectively

F 41 H 7/007 and 60 - 65 °.

The disadvantages of the known unit with reactive armor is that the lower region of the lid above the upper protective ball and the upper region of the lid under the lower protective charge are weakened zones, because the part of the lid that works on the attacking shell is minimal in area or completely absent.

In addition, protection against tandem cumulative weapons is not provided, as the protective charge detonates from the leading cumulative charge (SC) and passes the main SC coming after with a time delay and destroying the protected surface

The purpose of the utility model is to increase the effectiveness of the protective properties of reactive armor against all types of modern ammunition, including tandem cumulative.

This goal is achieved due to the fact that the unit with reactive armor to protect the surface to be closed from shells, comprising a housing fixed on the surface to be closed, divided by internal vertical armored partitions into honeycomb sockets, each of which is equipped with an upper pin and a protective flap installed at an acute angle, rocket armor, including the upper and lower rows of protective charges with caps, as an armored base for protective charges used additional armor plates installed with a gap parallel to the upper armor plate for the upper row of charges and parallel to the protective flap for the lower row of charges, made of working and structural parts, rigidly interconnected by a jumper with a thickness equal to 0.2 0.3 plate thickness,

- 2 at the same time, the working part of the additional armored plates is installed with a lateral gap relative to the internal vertical armored partitions equal to 0.2 0.3 plate thicknesses, their rear edges are rigidly connected to the armor inserts in areas equal to the thicknesses of the mentioned $ plates, and the connecting jumpers of the working and structural parts of additional armor plates are made in planes perpendicular to the planes of the upper armor plate and the protective flap; drawn from the line of intersection of these planes with the planes of the additional plates, and the angle between the surfaces of the armor inserts and the inner planes of the working parts of the additional armor plates is at least 90 ° along the gap between these plates with the upper armor plate and the protective flap, and in each honeycomb slot a protective flap and a protective armor plate installed parallel to it are rigidly fixed to an insert made with a thickness equal to the gap between them and a length equal to 0.4 0.5 lengths up to an additional protective armor plate, while the upper and lower cavities under the protective charges are made with a length equal to 1.5 f 1.7 the minimum width of the cavity.

An analysis of the main distinguishing features showed that: - the use of additional armor plates installed as an armored base for explosive charges, installed with a gap relative to the upper armor plate and the protective flap, reduced weakened zones and increased armor protection due to the use of the double-sided reflected throwing, especially when exposed to attacking danceable cumulative ammunition;

- 3 - the implementation of additional plates of two parts - working and structural, which are tightly interconnected by a jumper with a thickness equal to 0.2 "0.3 of the thickness of the plate, made it possible to use these jumpers as delivery links when the charges are triggered, which increased the speed of additional plates by the attacking shell and allowed to maintain the survivability of the armor structures located next to the cell, which was exposed to the attacking shell;

-installation of the working parts of additional armored plates with a lateral gap relative to the armored internal upper partitions equal to $ 0.2 - 0.3 of the thickness of the plates ensured the movement of the working parts without friction on the side surfaces of the partitions, which increased speed;

- a rigid connection of the rear edges of additional branded plates with armor inserts, made in areas equal to the thickness of the plates, ensured reliable fixation of the plates during all types of operation (before the explosion of protective charges);

- the implementation of the connecting jumpers of the working and structural parts of the additional armor plates in planes perpendicular to the planes of the upper armor plate and the protective flap drawn from the line of intersection of these planes with the planes of the additional plates, ensuring the angle between the surfaces of the armor inserts and the internal planes of the working parts of the additional armor plates is equal to at least 90s, at the length of the gap between these plates and the upper armor plate and the protective flap, ensure that working hours five plates with additional charge triggered

- 4 do not affect oppositely located additional plates and do not destroy them;

-installation in each honeycomb slot between the protective flap and the parallel additional last protective br @ nvoy insert plate, made of a thickness equal to the gap between them and a length equal to 2.4 t - 0.5 of the length of the additional protective plate, ensured a uniform level of protection by maintaining the same total thickness of the armor plates over the entire height of the protective block;

- the implementation of the upper and lower cavities under charges equal to 1.5 f 1.7 in length of the minimum cavity width, made it possible to use standard dynamic protection elements for the formation of explosive charges.

Moreover, the armored plates 14 and 15 are installed with gaps in (Fig. 2,3) parallel to the upper armor plate 5 for the upper row of protective charges 3 with a gap in and parallel to the protective flap 10 for the lower row of protective charges 4. The armor plates 14 and 15 are made up of a working gy (Fig. 4) and structural parts, which are rigidly interconnected by a jumper with a thickness of 0.2 ... 0.3 thickness of additional armor plates 14 and 15.

The working parts of the additional armor plates 14 and 15 are installed with lateral gaps w (Fig.Z) equal to 0.2 ... 0.3

. - 6 plate thicknesses 14 and 15, relative to the internal vertical armored partitions 9.

Strong edges p (Fig. 2,4) are rigidly connected to the armor inserts 16 and 17 in sections n equal to 3 ... 4 thicknesses of additional armor plates 14 and 15.

The connecting jumpers e working d and structural d parts of the additional armor plates 14 and 15 are made in planes perpendicular to the planes of the upper armor plate 5 and the protective flap 10, drawn from the line of intersection of these planes with the planes of the plates 14 and 15. Angle cЈ (Fig. 4) between the surfaces of the armor inserts 16 and 17 and the inner planes of the yaks of the working parts of the plates 14 and 15, at the bottom of the gap, between these plates with the upper armor plate 5 and the protective flap 10, is not less than 90 °.

- 7 work

When the armor-piercing-polskalibermy projectile F (FIG. 2 firing shots) gets into the cover 19 of the protective block I, the following occurs: the projectile G pierces the cover 19, while the resulting stream of fragments excites an explosive protective charge 3, which detonates and the resulting explosion products throw armor cover 19 towards the attacking shell G, destroying and deflecting it. At the same time, an additional armor plate 14 is thrown along with shell G (which managed to break through plate 14) in the air gap of the airway, perpendicular to the upper armor plate 5. In the case of a shell G falling into the lower region of lid 19, where the smallest part of this lid works , the projectile T will be affected (along the way) by the upper region of the additional armor plate 14, increasing the protective characteristics of the unit with reactive armor I. Moreover, only the working part of the additional armor plate 14 will be thrown, because the connecting bridge serves as a place for the destruction of the plate 14, thereby forming a delivery link, which allows the structural section d and the lower cavity to be preserved without destruction. After interacting with the lid 19 and the plate 14, the remnants of the core of the projectile G sequentially interact with the armor plates 5, II, 7 k and the actually closed surface 2.

A similar thing happens when the shell G & cover 20.

When exposed to a cumulative means of destruction D (Fig. 2, shootout) on the cover 20, breaks through it and excites an explosive protective charge 4, which detonates and formed

- 8 explosion products throw armor cap 20 towards the cumulative stream, dispersing it. At the same time, an additional armor plate 15 is thrown along the way with a cumulative stream (having managed to break through the plate 15) in the air gap in, perpendicular to the protective flap 10. Moreover, only the working part of the additional armor plate 15 is thrown, because the connecting bridge ei serves as a place of destruction of the plate 15, which allows the structural section of the di and the upper cavity of the submarine to be preserved without destruction

In the event of an attack of a tandem cumulative weapon D with a longer cumulative jet impact on the protective block I, a reflected throwing of the plate 15 from the protective flap 10 occurs. After hitting the working part of the plate 15 against the protective flap 10, the plate 15 starts to move in the opposite direction (towards cumulative stream), scattering its tail. After interacting with the cover 20 and the plate 15 (twice in tandem KSP), the remaining cumulative stream will sequentially interact with the armored shutter 10, plates 12, 13, 7 and the surface which is actually closed 2. The same occurs when the KSP enters the cover 19.

Thus, the proposed protective unit is a promising means of protecting enclosed surfaces when protecting objects of military equipment, moreover, from armor-piercing sub-caliber shells. “MSUOT of tandem cumulative weapons.
