RU2277215C2 - Method for delivery of war component of antitank antiroof mine to target - Google Patents

Abstract

FIELD: means for destruction of armored equipment, in particular, antiproof mines.

SUBSTANCE: the war component is ejected vertically upward to the preset altitude, the war component is started and performs a flight towards the target with the aid of a rocket engine, and attacks the target by a percussion core at the instant of flight over it. The war component is started towards the target at an altitude close to the target height from the horizontal position at a preset speed of vertically-translational motion upward with a subsequent motion of the war component in a flat trajectory in a narrow range of altitudes with destruction of the target perpendicularly to its surface.

EFFECT: enhanced war efficiency of the mine.

Description

The invention relates to methods for delivering a striking combat element (EB) to a target and can be used in anti-tank mines that are designed to defeat armored vehicles (BT) in the upper, most vulnerable, surface.

Currently, methods are known for delivering BE to a target, for example, a method that is used in an XM93WAM (Wide Area Mine) type anti-pitch mine (www.systems.textron.com) (see "Foreign Military Review", 1992, No. 1, p. .32). This method consists in the fact that a BE containing a warhead (warhead) with a projectile-forming charge (SPS) and a target sensor is fired towards the target at a certain angle to the horizon and moves along a ballistic trajectory, scanning the terrain beneath itself as a result of rotation relative to its transverse axis. When firing at a range of 100 meters, the flight altitude of the BE can reach 40 meters. At the moment of detection of the BT target by the sensor, the PPS is undermined, and the target is hit by a high-speed shock nucleus (UY).

The specified method has significant disadvantages:

- the low average flight speed of the BE and, as a result, the long delivery time of the BE to the target (3-4 s for a range of 100 m) allow BTs to effectively use the AwiSS type active protection system of the German company Diehl VA Systeme (http: //www.diehl. com). According to calculations, in order to reduce the effectiveness of such a system to zero, the flight time of the BE should not exceed 0.6 s;

- the attack of the target can occur at inclined ranges of up to 40-60 meters and small meeting angles with the upper surface of the BT, which leads to a loss of kinetic energy by 20-25% and even to rebound UY.

There is also a known method of delivering the BE of an anti-tank anti-bitumen mine to a target, which is our development and is published on a website on the Internet belonging to the FKP GkNIPAS http://www.aha.ru/. The method of delivering BE to the target is divided into two sections: vertical and horizontal. The first section includes the ejection of the combat element vertically up to a predetermined height, the second - flight BE towards the target using a rocket engine. The defeat of the target occurs by the strike nucleus at the time of flight over it. This method of delivering BE to the target, in comparison with the previous method, is devoid of some disadvantages:

- Increased BE delivery speed through the use of a rocket engine;

- the attack of the target occurs at large angles of encounter of the UY with the surface of the BT due to the use of horizontal launch.

However, this method has several disadvantages:

- the launch of the BE towards the target is carried out from the hovering position, and the subsequent flight of the BE occurs with a decrease in the trajectory due to the action of gravity;

- to achieve the required range, the launch height can reach more than 10 m, which increases the likelihood of detection;

- when starting at a height of 10 m, the distance to the surface of the BT in the initial section of the BE flight can reach 8 m, which affects the penetration ability of the UA.

The technical result of the application of the present invention is an increase in the combat effectiveness of an anti-tank anti-bitumen mine due to the optimization of the flight path of the BE. The optimal trajectory of the BE is a trajectory that, within a given range, lies in a narrow range of heights (flat trajectory) from 0.5 m to 1.5 m above the surface of the BT and deviates from the horizontal by the value of the trajectory angle of plus or minus 1.5 °. An increase in the range of heights in the lower limit entails an increase in the probability of a frontal impact of EBs in BTs, which in our case is unacceptable. An increase in the height range in the upper limit entails an increase in the probability of BE detection by the BT protection system and a decrease in the breakdown ability of UE. An increase in the range of the trajectory angle increases the angle of encounter of the UW with the surface of the BT, which leads to a decrease in the probability of damage to the BT.

BE trajectory is divided into two sections: vertical and horizontal. In the first vertical section, the BE equipped with the PPS and the target sensor, which are oriented vertically downward, moves vertically upward from the initial horizontal position, maintaining a horizontal position. This movement is set using a catapult. The essence of the invention lies in the fact that at a given height close to the height of the BT ≈ 2 m, having a certain vertical speed, the BE starts horizontally towards the target with the help of a rocket engine (RD) and moves along the second horizontal section of the trajectory. This section of the trajectory lies in a narrow range of heights (flat trajectory) and deviates from the horizontal by the value of the trajectory angle plus or minus 1.5 °. The decrease in the BE trajectory under the action of gravity is compensated by the vertical speed, which ensures the flight of the BE along the lay trajectory at a given range.

The stated essence of the invention is illustrated by figure 1 and figure 2, which shows one of the possible devices with which you can deliver BE 1 to the target according to the described method.

The method of delivering the BE 1 to the target is as follows: BE 1 containing the warhead 2 with a projectile-forming charge and the target sensor 3, which are oriented vertically downward, are catapulted vertically upward, using the catapult 4 with an initial speed V ₀ and at a height of H _y , having a vertical speed V _y , using a rocket engine 5 starts horizontally towards the target. When flying over a target, BE 1 detects it with a target 3 sensor and strikes UY from above. As an example of the implementation of the claimed capabilities of the proposed method, Fig. 3 shows the results of calculating the trajectory parameters of a hypothetical mine with a mass of 15 kg, a total pulse of RD 2100Ns and an operating time of 0.3 s. The initial vertical speed V ₀ = 8 m / s, the height and vertical start speed H _y = 2 m and V _y = 6 m / s, respectively.

From the above data it can be seen that the BE flight occurs in a certain corridor of Y heights from 2 m to 3 m with a TETA pitch angle of plus or minus 1.5 °, which ensures a flight over the target and its UY is hit in the upper surface normal to this surface.
