Abstract

FIELD: fighting equipment.

SUBSTANCE: adjustable mortar bomb comprises a body equipped with a nose cone in its front part and a vane in its tail end, a filling with an ignition set and a targeting system with a power source. The bomb is equipped with an armoured live load detection and recognition sensor provided in the nose cone of the body and actuated at a wave length of 3-5 mcm; a sensor output is connected to an input of a targeting system, and a driven extension rod mounted on the nose cone and configured to have a mechanical effect on a fuse for actuating when the rod contacts a target of a land surface.

EFFECT: more effective destruction of enemy's armoured live load.

Description

The invention relates to weapons and military equipment (IWT), namely, to correctable mines, and can be used in all existing and under development mortars and self-propelled artillery to combat tank dangerous personnel (TOZhS) - primarily with calculations of anti-tank guided missile launchers (ATGM).

The fight against SSC is a difficult technical task, because TZHS is a small, disguised target, usually hidden in trenches. In addition, calculations with anti-tank missile launchers after a missile launch are moved to a new position, which complicates their detection and destruction by conventional means (machine gun, grenade launcher, automatic gun, mortar, etc.).

At the same time, calculations using ATGMs can cause significant damage to the advancing side (primarily due to the destruction of heavily armored weapons and military equipment).

Adjustable mines are known to be used in portable and towed mortars of units of the Ground Forces to destroy enemy manpower, military equipment, buildings, structures, etc. (see Adjustable Artillery Shells. Military Review Website, July 7, 2011). For example, self-propelled mortar mounts (SMU) of the 2C4 Tulip type are known, which are equipped with 240 mm Smelchak-type mines that can be adjusted in the final section of the trajectory, as well as a 152 mm complex with corrected artillery shells created on the basis of this technology "Centimeter".

These SMUs primarily solve the problems of destruction of weapons and military equipment, as well as buildings, structures, etc. Shooting with corrected mines from the SMU is carried out according to the target designation of an advanced observer having a reconnaissance device and a laser target illuminator, with which he irradiates the target after issuing target designation at the SMU. At the final section of the mines flight path, its homing head detects the laser radiation of the backlight reflected from the target and determines its coordinates, providing guidance of the mine to the target. When hit in a target or soil, a mine explodes with a contact fuse.

The closest in technical essence is the Smelchak corrected mine, which contains a body made with a fairing in the front and a stabilizer in the rear, a charge with a fuse and a targeting system with a power source (see. Corrected artillery shells. Military website Review ”, July 7, 2011).

The disadvantages of the known adjustable mines are:

- mines are used mainly for weapons and military equipment, fortifications, command posts, etc., that is, for objects that can be accurately illuminated with a laser illuminator;

- firing by corrected mines can be conducted only if there is a direct line of sight between an observer with a laser illuminator and a target, as well as with sufficiently high cloud cover.

The indicated disadvantages of the corrected mines and the methods of their use do not allow their effective use to defeat TJS.

To ensure effective destruction of the enemy’s TLC, the corrected mortar mine contains a body made with a fairing in the front and a stabilizer in the rear, a charge with a fuse and a targeting system with a power source, while the mine is additionally equipped with a tank dangerous personnel detection and recognition sensor located in the fairing of the body and made with the possibility of working at a wavelength of 3-5 microns, while the output of the sensor is connected to the input of the guidance system of the mine on the target, and a retractable rod drive installed in the fairing body mines and adapted to effect on mechanical mine fuze with its contact with the target or the ground for driving the fuse in deystvie.Suschnost invention is shown in the figure, which shows a general view of the proposed corrected mines. In the middle part of the mine there is a charge 1 and a fuse of push action. At the front of the mine there is a fairing 2, inside which a detection and recognition sensor TZhS 3 and a retractable rod 4 with a drive are installed. In the tail of the mine are placed mine guidance system with power source 5 and stabilizer 6.

The defeat of TZhS mine is as follows. After a mortar shot in the initial section, the mine moves along a ballistic trajectory due to the kinetic energy received during the shot. By the time when the acceleration of the mine’s movement is approximately equal to zero, the power source is started in the guidance system, the drive mechanism of the retractable rod 4 is turned on, the guidance system of the mine 5 and the detection and recognition sensor TZhS 3 are supplied. The target detection and recognition sensor 3, which is an infrared receiver operating at a wavelength of 3-5 μm, with a signal processing system, detects a target of the TROJS type (by temperature, shape, size, on the ground by detecting and recognizing signs) and others), determines the location of the target relative to the trajectory of the mine, generates control signals that enter the guidance system 5 of the mine, which controls the stabilizer 6, thus pointing it at the target. Having reached the surface of the earth or target, the extendable rod 4 actuates the mine fuse, which initiates the detonation of charge 1. Due to the extendable rod 4, the mine is detonated above the earth's surface, at a height equal to the length of the rod, and due to the almost vertical path of the mine near the surface its land fragments fly parallel to the earth’s surface, increasing the radius of destruction of the enemy’s manpower in comparison with the explosion of mines directly on the surface of the earth.

The installation of a sensor for detecting and recognizing a target operating at a wavelength of 3-5 μm ensures the detection and recognition of SARs both day and night under normal and difficult visibility conditions (smoke, dust, strong haze, fog) and does not require target illumination. For mines with such a sensor does not require accurate determination of the coordinates of the target. It is enough to know the location of the enemy units.

The advantages of the claimed invention over the known technical solutions are:

- passive mode of operation (does not require target illumination);

- no exact indication of the coordinates of the target is required;

- mines can be used day and night, in normal and difficult conditions of visibility;

- reduced consumption of mines and time to hit the target;

- the zone of destruction of manpower increases.

The indicated advantages of the claimed invention significantly expand the capabilities of mortar weapons in combating anti-aircraft missile defense and can reduce the loss of weapons and military equipment from enemy ATGM calculations.
