Abstract

FIELD: ammunition, in particular, bounding mines.

SUBSTANCE: the ground fragmentation mine has a bursting tube with a fragmentation charge inserted in it, and a device for ejection of the charge from the tube. The fragmentation charge is made in the form of two hinge-joined semi-cylinders, each representing an independent fragmentation charge. The mine is adaptive and, depending on installation, may be used for realization both of circular and directed fragmentation fields.

EFFECT: expanded tactical potentialities of use of the mine.

Description

The invention relates to ammunition, and more specifically to engineering mines with a tossed fragmentation charge.

OZM-72 fragmentation jumping antipersonnel mine with a circular fragmentation field (see P. D. Gutenko, G. A. Matin. Mine weapons. M.: DOSAAF USSR, 1988) includes a cylindrical body, which is also a knockout glass inserted into It has a fragmentation charge, consisting of a body, a layer of ready-made striking elements and an explosive charge, as well as a fuse connected by a cable to the bottom of a knockout cup. The fragmentation charge is ejected by a knock-out powder charge driven by an igniter capsule triggered by wire tension.

The disadvantages of mines with a circular lesion are well known:

- low density fragmentation field, which does not allow for reliable overlap of the most threatened areas;

- a certain danger to their troops in the location of minefields in areas of direct contact with the enemy.

It is these circumstances that make it necessary to have at least two types of anti-personnel mines - mines with a circular destruction field such as OZM-4, OZM-72 and mines with a directed destruction field such as MON-100, MON-50, MON-90, which complicates the production and supply of troops. The present invention seeks to remedy this drawback.

The technical solution consists in the fact that the ejected fragment charge is made in the form of two articulated semi-cylinders, with the plane of the semicylinder connector being located along the wire tension line, and the hinge facing the tension wire, equipped with a mechanical or pyrotechnic device for opening the semicylinders and a fragmentation field type switch.

Figure 1 is a longitudinal section of a mine installed in the ground; figure 2 is a cross section of a fragmentation charge when folded; figure 3 is a cross section of a fragmentation charge in an open form; 4 is a diagram of the action of mines when installed on a directional fragmentation action.

The mine (Fig. 1) includes a knockout cup 1 and an openable fragmentation charge 2 inserted into it. On the lid 3 of the cup there is an igniter 4 with an impact mechanism 5 driven by a tension wire 6. In the space between the charge bottom 2 and the bottom of the knockout cup 1 there is a knockout charge of gunpowder 7 connected by a tube 8 to the igniter 4 and a cable 9 connected by a lower end to the bottom of the cup and the top with a fork 10. Actuator 11 of mine opening and detonation, including a shock mechanism, capsule -flame rer pyrotechnic charge, the detonator and the retarder is set in one of the half cylinders and is connected to the charge switch mounting rod 12 outputted on cover mines.

Figure 2 shows a cross section of a fragmentation charge. The cylinder body has two thin-walled shells 13, the space between which is filled with ready-made striking elements 14, and a flat wall 15. The inner cavity of the half-cylinder is filled with a charge of explosive 16. The half-cylinders are connected by hinges 17. The charge is equipped with stoppers that fix the half-cylinders in the open state (Fig. 3).

The mine is installed in the ground so that the plane of the connector is located along the line of the tension wire, and the hinge is turned towards the wire. When installing the switch 12 is installed in one of two positions:

- undermining with the formation of a circular fragmentation field;

- undermining with the formation of a directional fragmentation field.

When the tension wire is touched, the expelling powder charge 7 is ignited, the combustion products of which the fragmentation charge 2 is thrown up from the glass 1. After unwinding the cable 9 to its full length in the case of installing a “circular field”, the ignition is directly transferred to the detonator capsule and detonated with the formation of a circular field.

If the switch is set to the “directional field” mode after unwinding the cable 9, the fork pin 10 disengages the half-cylinders while igniting the pyrotechnic charge revealing the fragmentation charge by turning the half-cylinders around the hinges. After opening through the moderator, the detonator capsule is detonated with the formation of a directional field (Fig. 4). The transfer of detonation to the second half cylinder is through the contact surface 18.

Thus, the mine is adaptive, i.e. depending on the installation, it can be used to implement both circular and directional fragmentation fields, which greatly expands the tactical possibilities of its application. In terms of dimensions and a significant part of the nodes, it is unified with the standard mine OZM-72.
