Abstract

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to antitank and sea mines and is designed to destroy all land moving equipment and to strike ships. Mine has two sensors that show entrance of enemy vehicles in the affected area, separated according to direction of enemy equipment- the first and the second ones, it also has a differential response device, which reacts to the direction of the target movements.

EFFECT: safety improving for one's advancing troops and ships and increase the effectiveness.

Description

The invention relates to anti-tank and naval mines, and is intended to destroy all moving land equipment, and to destroy ships (mainly in the fairways). In mass production, which reduces the cost of mines, and when using capacitive or infrared sensors, it is possible to use such mines in the anti-personnel version.

Mines are known, in particular electromagnetic anti-tank mines, see, for example, US Pat. No. 2400700. Danger for their advancing troops and ships can conditionally be considered their flaw.

The objective and technical result of the invention is safety for its advancing troops and ships, as well as increasing the effectiveness of the action.

For this, the mine contains, as usual, a hull, a charge and a fuse, but it has two sensors for enemy vehicles to enter the affected area (hereinafter “sensors”), spaced in the direction of movement of the enemy vehicles - the first and second, and also has a differential response device for the direction movement of the affected object. That is, such a mine strikes objects moving in one direction and “misses” objects moving in the opposite direction, see FIG. 1, where the arrow shows the direction of movement of enemy equipment. We will call such mines “directional” (not to be confused with a directed explosion).

The mentioned device can be a simple electrical, electronic, pneumatic, hydraulic or mechanical circuit that provides a mine explosion when passing an object from the first sensor to the second, and disables the mine fuse when passing the object in the opposite direction.

As an electrical variant of such a device, the electrical circuit shown in FIG. 2. It consists of an electric power source connected to the mine fuse through the make contact of the second sensors, the switching contact of the first sensor, and the opening contact of the relay, and the relay is connected to the power supply through the contact of the second sensor, its make contact and in parallel through the switching contact of the first sensor .

In addition to obtaining the specified directivity property, such a mine has greater effectiveness in defeating enemy vehicles, since it does not explode in the place where the second sensor is located, but behind in the direction of movement of the target, that is, in the very middle of the target. To do this, the second sensor should be located in front of the mine. Then, if the target has a trawl of any design (contact, electromagnetic), then the mine will explode not under the trawl, but under the object. To enhance this action, both sensors can be carried forward from the mine in the direction of movement of the target.

In case of infantry defeat - on the contrary - the first sensor should be located behind the mine, and the second - on the mine. Then the mine will explode under the infantryman. Although the explosion in a meter from an infantryman may be even more dangerous for him. So if the enemy infantry is equipped with anti-mine boots, then the arrangement of sensors as for equipment in this case is preferable.

In FIG. Figure 1 shows such a mine with two pressure sensors - the first along the direction of the strike of the target — 1, and the second — 2, connected to the mine by cable. The first sensor is located directly on mine 3.

In FIG. 2 shows the electric circuit of the mine, where: 1 - the first sensor and its contact, 2 - the second sensor and its contact, 3-M - mine fuse, P-4 - relay and its contacts P1 and P2.

The mine works like this: if the enemy advancing object moves in the direction shown by the arrow, then first the sensor 1 closes, then the second sensor 2, the voltage is supplied to the 3-M fuse, and the mine explodes.

If our advancing equipment moves in the opposite direction, then sensor 2 closes first, the voltage through switching contact 1 (it must be installed in this position) is applied to relay 4, which opens the fuse circuit with contact P1, and at the same time the relay is self-locking by contact P2. Then our technician runs into sensor 1, but there is no explosion because contact P1 is open. Then our equipment moves out of contact 2, and the entire circuit is de-energized and returns to its original state.

This mine will allow the enemy to unexpectedly go on the attack in a mined space, and also increase the damage to enemy equipment.
