RU2707836C1 - Method of target destruction by ammunition with impact nuclei - Google Patents

Abstract

FIELD: military equipment.

SUBSTANCE: invention relates to military equipment and can be used in development and use of ammunition with warheads forming impact nuclei. According to the method, after discharge from ammunition, warheads fall to the ground, making circular motions. At that, terrain in zone of combat elements falling is scanned by sensors installed on these elements. These sensors allow fixing an armored target in the direction of the firing element falling. Besides the target identification sensors, a radar sensor is mounted on the combat element, which is used to record the moment when the combat element is lowered below the specified height from the ground surface. Metal grid is installed before lining, from which impact nuclei are formed. When an armored target is found, a grate is fired from the firing element and the firing element explodes. Under action of flat detonation wave in explosive substance of fighting element one large nucleus is formed. In case the combat element has fallen to the height below the preset one, and the armored target was not detected, a control command is sent from the sensor-radar to another operating mode. Command is sent to blasting of explosive by creation of spherical wave of detonation. At the same time thin metal lining is thrown towards metal grate, dissections of lining into separate fragments. In the form of multiple nuclei they fly in direction of falling of warhead, creating a large area of destruction.

EFFECT: increased efficiency of ammunition.

Description

The invention relates to military equipment and can be used in the development and use of ammunition with shock nuclei formed by an explosion of thin metal shells.

In modern ammunition, strike nuclei are usually formed using self-aiming combat elements. Self-aiming combat elements (SPBE), search for targets in the final flight area when approaching the ground. Parachutes are widely used to brake and stabilize SPBEs. In the search area, the self-aiming combat element is usually located at a certain angle to the vertical, and rotates around the longitudinal axis. The sensors of the combat element make an overview of the terrain, and the shape of the viewing area is a converging spiral. When a target is detected, the combat element is undermined, an impact core is formed, which strikes the target. Widely known SPBE SMArt (Germany), SADARM (USA), the descriptions of which are given in the magazines: "Foreign Military Review", No. 11, 1994; "ARMADA", 1998, No. 6; GLOBAL DEFENSE REVEW, 1998

The disadvantage of such combat elements is that in the absence of an armored target in the field of view of the sensors, the combat element explodes at the moment of contact with the terrain, practically without causing any damage to the enemy.

In the proposed technical solution to increase the effectiveness of such ammunition, it is proposed to search for armored vehicles using sensors at altitudes greater than the minimum, approximately equal to the three maximum tank sizes (20-25 m). In the absence of such a target (when lowering the combat element to a height less than specified), the combat element, when undermined, forms not one, but many shock nuclei. In this case, objects (manpower, unarmored targets, etc.) are defeated over a large area. Due to this, the effectiveness of the ammunition is increased.

The moment of undermining the combat element is controlled by an electronic system installed in the element itself, and programmed in the manufacture of elements.

As a means of delivery of combat elements, planning aerial bombs of the CBU-971B type, artillery shells of the Smart-155, PI-SADARM, BONUS type, cruise missiles of the AGM-158 JASSM and RGM / UGM-109D type, ATACMS, M30 missiles, PC30 MLRS and MARS.

As sensors for target identification, sensors similar to those installed in SMArt SPBE and others (see above) can be used.

As sensors to determine the minimum height of the element can be used miniradars used in non-contact radio fuses, for example, based on autodyne, which allow you to record heights up to 20-25 meters from the surface (Kuznetsov N.S. Suggestions for the use of autodyne in modern radio fuses // Scientific and technical collection of the State Research Center of the Russian Federation FSUE TsNIIHM named after DI Mendeleev, Ammunition. - 2017. - No. 2. - p. 38-43).

Techniques for the formation of many striking elements using the multilayer metal linings presented above the combat elements are considered in the author's work (Kuznetsov N.S. D.I. Mendeleev ", Ammunition, 2016, No. 2, pp. 54-59).

An explanation of the principle of operation of combat elements according to a given program is shown in the figure of FIG. one.

FIG. 1. The combat element and the modes of its operation: a) combat element: 1 - the electronics block of the sensor and fuse control system, 2 - detonation wiring block, 3 - the combat element case, 4 - explosive, 5 - multilayer cladding, 6 - grille, 7 - sensor devices, 8 - fuse; b) the mode of undermining the combat element with the formation of a spherical wave of detonation A and many shock nuclei; c) the mode of undermining the combat element with the shooting of the lattice 6, the formation of a plane wave of detonation B and the formation of many shock nuclei.

This figure shows three (a, b, c) states of a combat element and a simplified design of the element itself, and also shows the fronts of the generated detonation waves (A and B) for various types of detonation, namely: a) when an armored target is detected (a metal is fired off lattice 6, a plane detonation wave B is formed, and one large core is formed); b) in the absence of an armored target when lowering a combat element below a predetermined height (a spherical detonation wave A is formed, and many shock nuclei are formed).

The formation of various types of detonation waves in an explosive is carried out using multipoint initiation controlled by a fuse, which, in turn, receives control commands from the electronics unit 1.

The proposed technical solution works as follows.

The delivery of combat elements to the target area is carried out by various carriers: air bombs, artillery shells, etc. After the release, the combat elements fall to the ground, making circular movements to review the terrain in the fall zone. Moreover, the terrain in the zone of incidence of combat elements is scanned by sensors mounted on these elements. These sensors allow you to fix the armored target in the direction of the fall of the combat element. In addition to target identification sensors, a radar sensor is installed on the combat element, which captures the moment the combat element descends below a predetermined height from the surface of the earth, and a metal grill is installed in front of the facings from which the impact cores are formed. When the claddings fly out of the combat element, they are dissected by a lattice, forming many high-speed metal cores.

Upon detection of an armored target (identified using sensors), a lattice is fired from a combat element and the combat element explodes. Under the action of a plane detonation wave in the explosive 4 of the combat element 3, one large core is formed. A plane detonation wave B is formed in the detonation wiring block 2 using a controlled fuse 8.

If the combat element has dropped to a height below a predetermined one and the armored target has not been detected, a control command is sent from the radar sensor to a different operating mode of the element, namely, a command is sent to detonate explosive 4 by creating a spherical detonation wave B. When this thin metal cladding 5 are thrown in the direction of the metal grill 6, it is cut into separate fragments, and in the form of many cores fly in the direction of the fall of the combat element, creating a large area of destruction. These cores are able to hit lightly armored vehicles and manpower of the enemy.

The use of such a scheme for undermining a combat element can increase the effectiveness of ammunition.

The stated information about the claimed invention, characterized in an independent claim, indicates the possibility of its implementation using the described in the application and known means and methods. Therefore, the claimed method meets the condition of industrial applicability.
