Description

COMBAT PART OF ANTI-TANK AMMUNITION

FIELD OF ENGINEERING

The invention relates to anti-tank guided missiles (ATGMs), rocket-propelled grenades, unmanned aerial vehicles (UAVs) and others. It is intended to overcome the active protection of tanks and armored vehicles.

PRIOR ART

Anti-tank ammunition is known as:

- anti-tank guided missile (ATGM). This type of missile varies in a wide size range, and can be launched from both individually portable installations and large ones that require several servicemen and corresponding military motorized units to operate and transport. They are powered by solid fuel jet engines, are equipped with an on-board control system (control unit) and are controlled by operator commands or using a homing system. The warhead of modern missiles is usually tandem cumulative - it contains 2 charges (head and main). The head charge is designed to destroy reactive armor and anti-cumulative shields. The main charge provides penetration of the main armor and destruction of the target. Missiles of this type can also be attached to motor vehicles or aircraft. Thanks to the use of missiles of this class in the conduct of modern wars, the infantry is given a chance to effectively counter light and medium tanks.

- hand anti-tank grenades. Some of them are equipped with a standby cumulative charge. Also known is a Russian hand-held single-shot anti-tank grenade launcher RPG-ZO designed to destroy modern tanks equipped with active protection systems and which consists of two parallel tubes, one containing the main anti-tank grenade and the other containing a target simulator missile with an identical trajectory and radar signature with the main grenade. The smaller target simulator exits the barrel first, followed by the main PG-30 grenade after a short delay. The target simulator activates the active protection system before the main anti-tank grenade has reached the target. The disadvantage of this ammunition is that it has an effective range of up to 140m, and the probability of overcoming the active protection of tanks is not high, - unmanned aerial vehicles (UAVs) and others designed to destroy tanks and armored vehicles. Some of them are also equipped with a standby cumulative charge.

Most modern long-range ballistic missiles on approach launch up to 10 or more dummy warheads, making it difficult for the enemy to identify and destroy the real warheads, or otherwise disrupting the anti-missile defenses to detect the real warheads.

The active protection of tanks is also known - a system located on a tank or other armored vehicle, which, upon detection of anti-tank ammunition approaching it, destroys, or at least strongly weakens, the effect of the attacking ammunition. Different names are used in the literature - active protection complex (ACC), active protection system (ACS). The system includes radar or other missile detection systems. After the system detects an anti-tank munition approaching the tank, the system sends a command to launch a charge in the threatened direction, which explodes and creates a cloud of fragments and a blast wave destroying the anti-tank munition or significantly reducing its damage. The use of active protection systems can significantly (two to three times and more) increase the possibility of tank survivability.

It follows that the known anti-tank ammunition has no ability to overcome the active defense of tanks.

TECHNICAL ESSENCE OF THE INVENTION

The task of the invention is to ensure reliable overcoming of the active protection of tanks and armored vehicles from anti-tank guided missiles (ATGMs), rocket-propelled grenades, unmanned aerial vehicles (UAVs) and others.

This task is solved with the development of a new combat unit of anti-tank ammunition (anti-tank guided missiles (ATGM), '3reactive grenades, unmanned aerial vehicles (UAVs) and others), consisting of a body (1), in which are located: a block for control(2), target range sensor(H), explosive device(5) and target simulator(s)(4).

-Target simulators (4) are small cylindrical bodies powered by solid fuel jet engines and stabilized in flight by rotation about their longitudinal axis or by stabilizers. They have an identical trajectory and signature to the anti-tank munition, and/or disrupt the target's active defense systems, and travel at a higher speed than the anti-tank munition. These will be classified by the target's active defense systems as an anti-tank munition attacking the target, causing them to be triggered and a command is given to fire a charge in the threatened direction, which detonates and creates a cloud of shrapnel and a blast wave destroying the target simulator. Because the destruction zone of the charge is relatively small, the charge is unable to hit the anti-tank munition that follows. The cloud of debris and explosive plasma formed after the destruction of the charge and the target simulator masked the approaching anti-tank munition. Re-detection of the anti-tank munition is possible only after it exits the debris cloud at distances significantly smaller than necessary to counter the threat of active defense systems. Relaunching a charge in the threatened direction is often impossible or requires time to hit the target. Target simulators may also create active or passive interference with the target's active defense systems, interfering with the detection of the anti-tank munition. A target's simulators may be one or more. With one target simulator it is possible to place it centrally along the longitudinal axis, and with more target simulators symmetrically around the longitudinal axis of the anti-tank ammunition. In order to avoid their deviation from the direction of flight of the anti-tank ammunition to the target due to the centrifugal forces from the rotation of the anti-tank guided missile ATGM or rocket-propelled grenade relative to its longitudinal axis, they can be located at a compensating angle. It is possible to successively launch several simulators entering the area of action of the active protection of the target in succession and thus causing the consumption of anti-missile charges. It is also possible to simultaneously launch several simulator '4' tors moving at the same speed and entering the area of action of the active protection of the target at the same time. It is also possible to simultaneously launch several simulators moving at different speeds and entering the zone of action of the active protection successively.

- The explosive device(5) (single or tandem cumulative charge, or other charge) when detonated deals damage to the target.

-The rangefinder sensor (3) for the distance to the target can work on an optical, laser or other principle. It measures the distance to the target and when a preset distance is reached it sends a signal to the control unit (2) to fire the target simulator(s) (4). -The control unit (2) fires target simulator(s) (4) on a signal from the rangefinder sensor (3) upon reaching the preset distance to the target.

The invention relates to anti-tank ammunition hitting the target (tanks and armored vehicles) in horizontal and vertical direction.

The advantages of this solution are:

- increasing the probability of hitting tanks and armored vehicles with active protection

- the modernization of already existing anti-tank ammunition to the model of the invention is possible
