Description

The invention relates to the field of military equipment, in particular to the field of protection of armored objects from anti-tank ammunition.

Known automatic systems for active protection of armored objects:

English tank missile defense system TAMS firm "Marconi";

Israeli "Attack Threat Warning System" of the Merkava MK3 tank;

American "Active Tank Defense System" (SLID complex);

Domestic complexes "Drozd" and "Arena".

In the general case, the active defense complex consists of a detection system, an information processing and control system, and an arms system.

The basis of the TAMS system is a lightweight pedestal installation with a 1-kW servo drive, on which two Marconi radars are mounted and an armament system in the form of two coaxial 7.62 mm machine guns at a rate of 1,200 rpm. The maximum effective range of TAMS is in the range of 600-900 m, and an ammunition stow of 400 rounds is enough for 20 rounds (20 rounds per missile).

In the Israeli Merkava tank attack warning system, a target is detected at a distance of 20-25 m from the tank by electron-optical sensors mounted on the upper surface of the vehicle’s body along its perimeter and is hit at some distance from the tank by means of counteraction. The weapon system is a launcher for firing at a signal from a missile (grenade) detection system with a high-explosive or fragmentation warhead. Launchers are located around the perimeter of the tank.

In the American SLID complex, a target is hit by a small-sized guided projectile - an interceptor. The range of hitting a target with an SLID projectile is 100 m from the protected armored vehicle.

Some of the KAZ reviewed have proven effective against ATGMs and anti-tank grenades (Grenades). The probability of destruction of ATGM and GHG by known complexes is more than 0.7. Due to the difference in the design of the ammunition, the different locations of the fuses and warheads in the munition housing, the high-explosive fragmentation of the protective munition does not always lead to destruction of the target. In some cases, the action of protective ammunition leads to the operation of the attacking ammunition on the trajectory with the formation of a cumulative jet. If the cumulative funnel remains intact, then the impact of the cumulative jet on the protected object may be sufficient to defeat it, especially if the protected object is a light category machine by weight.

In addition, such KAZ weapons systems are generally not effective against armor-piercing sub-caliber ammunition. This is primarily due to the high speed of such ammunition, their stability in flight, the relatively large mass and small cross-sectional area.

All KAZ weapon systems are characterized by low speed due to the low speed of delivery of protective ammunition to the meeting point with the target.

Closest to the technical nature of the proposed is the armament system of the domestic active defense system "Drozd" / 1 /. In the Drozd active defense system, the weapon system consists of four twin armored units located at an angle of 20 degrees. to each other. Each armored unit serves a sector of 20 degrees. As a protective charge, a 107 mm high-explosive fragmentation projectile is used, the detonation of which occurs on command from a remotely-temporary fuse at a distance of about 7 m from the protected machine.

The disadvantage of this weapon system is its low efficiency when exposed to an armor-piercing projectile, as well as low speed, due to the low speed of delivery of protective ammunition to the meeting point.

The aim of the present invention is to increase the speed and efficiency of the weapon system of the active defense complex.

This goal is achieved by the fact that as a weapon system a protective munition is used in the form of a warhead with a cumulative funnel with a large opening angle operating on the principle of a "shock core" and mounted on a rotary base connected to the control system of the defense complex.

The principle of operation of the proposed weapons system is as follows. After the detection system began to accompany the target and determine its parameters, the signal from the processing and control system is fed to the rotary base actuator, which begins to work out the direction to the target in two planes. At the calculated time, a control signal is supplied to the fuse of protective ammunition and it is undermined. As a result of detonation, a striking element is formed - the “impact core”, which, depending on the purpose, can have a diameter of up to 30-40 cm and armor-piercing ability of up to 50-80 mm of medium-hard steel monolithic armor.

The speed of the striking element reaches 2-3 km / s. Thus, the striking element will be delivered to the meeting point faster in time than in all known systems (bullet speed - about 900 m / s, ammunition speed of the KAZ "Drozd" - 120 m / s), and, therefore, the proposed technical solution will allow increase the speed of the active protection complex.

Compared with the prototype, the hit of the striking element - the “strike core" - in the PG, ATGM or armor-piercing sub-caliber projectile will lead to its complete defeat. According to estimates, in this case, the residual armor-piercing effect of the attacking ammunition will be completely absent.

This weapon system allows you to hit the target at various distances from the protected object and allows you to use the complex with such a weapon system even on lightly armored vehicles.

To increase the area of damage, the angle of the cumulative funnel solution, it is advisable to choose from a range of 120-160 degrees.

The proposed weapon system can be embedded in the object along its perimeter or carried over the object.

Compared with existing weapons systems, the use of the proposed system will require increased accuracy in determining the coordinates of the target, which currently does not present technical difficulties. The adjustment of the flight direction of the striking element at the time of its detonation is carried out additionally by changing the place of initiation of the protective munition. For this, the protective munition (warhead operating on the principle of a “strike nucleus”) has several initiation points located in different places of the munition relative to the cumulative lining.

The main advantages of the proposed technical solution over the well-known are high speed, due to the high speed of delivery of the striking element of the "impact core" to the meeting point with the target, as well as the increased effectiveness of the destruction of any ammunition due to its high armor penetration even when using cumulative cladding with a large aperture angle.

The proposed solution allows us to make the KAZ multiple-weapon system, providing protection for the sample from almost all directions with a significant reduction in the mass of the weapon system.
