Description

The utility model relates to the field of ammunition and can be used as a means of combined physical and functional destruction of armored vehicles, in which, in addition to the main damaging factor (cumulative jet), an additional damaging factor appears - the action of powerful electromagnetic pulses (MEMP) that can affect the system active protection (SAZ) and electronic components of targets.

To destroy armored vehicles (self-propelled guns, tanks, etc.), mainly cumulative ammunition (shells, bombs, cumulative warheads of unguided and guided missiles) are used. In [1], the anti-tank aerial bomb PTAB-1M is described. It contains a steel case with an explosive charge (BB), copper lining and a fuse. Fuse type - contact. The defeat of the target is carried out only due to the action of a metal cumulative jet, which has an armor-piercing, incendiary and initiating effect. The armor penetration of such a bomb is 200 mm.

When meeting with an obstacle (armor), the initiating pulse from the head fuse is transmitted to the bottom detonator through a channel that runs along the axis of the shaped charge. As a result of compression of the copper cladding by detonation products, a metal cumulative jet is formed, which pierces homogeneous armor 200 mm thick (normally). The RBC-500 PTAB-1M cassette was developed for the PTAB-1M element.

Modern armored vehicles (in particular, tanks) are supplied with active protection equipment (SAZ). It includes an electronic system for automatic detection, selection and tracking of incoming objects. She issues a command to shoot special fragmentation BP, destroying dangerous objects on the way. The effectiveness of the SAZ against such relatively low-velocity objects as anti-tank bombs, rocket-propelled grenades or guided anti-tank missiles is close to absolute.

It is obvious that the SAZ is a unique and fairly reliable line of defense, which must be overcome by means of destruction.

Known warhead based explosive cumulative generator [2], which is the closest analogue of the proposed utility model and selected as a prototype.

The warhead based on an explosive magnetic cumulative generator consists of a body with a main charge of a high explosive of cylindrical shape placed in it with a central axial cavity in which the solenoid winding and the radiation circuit winding are located on top, an additional shaped charge with a lining made of high magnetic permeability material facing towards the main cylindrical charge, contactor, vibrator, power source (capacitor battery), contactors.

These shortcomings are eliminated by the prototype. This warhead has a combined damaging effect of high-explosive fragmentation and electromagnetic, but insufficient cumulative action.

The objective of this utility model is to create a more effective means of defeating protected targets (armored vehicles), in which, in addition to the main damaging factor, for example, a cumulative jet, an additional damaging factor appears - electromagnetic (MEMI action), capable of influencing the active protection system.

The utility model is illustrated by drawings: figure 1 - structural diagram of an anti-tank bomb of combined action; figure 2 - shaped charge; figure 3 - General view of the anti-tank bomb. Figure 1 shows an anti-tank bomb of combined action, consisting of a housing 3, acting as a fragmentation shell, with the main charge of a high explosive of cylindrical shape placed in it with a central axial cavity 4, in which the solenoid winding 5 and the radiation circuit winding 6 are located on top, additional shaped charge 8 with lining 7 made of high magnetic permeability material facing the main cylindrical charge, contactor 1, vibrator 2, power source (capacitor battery) 11, contactors 9, 10. The diameter of the additional shaped charge is equal to the diameter of the main explosive charge substance, while the ratio of the height of the shaped charge to the diameter of the shaped charge at the base of the shaped recess is approximately 3, and the ratio of the depth of the shaped recess to its diameter is approximately 1.5.

At the same time, the ratio of the height H _C of the shaped charge to the diameter D _C of the shaped charge at the base of the shaped recess is approximately 3, and the ratio of the depth of the shaped recess h _B to its diameter d _C is approximately 1.5 (figure 2).

The proposed technical device works as follows.

The detonation of the shaped charge 8 is synchronized so that under the action of the detonation products a metal cumulative jet is formed at the moment when the initial magnetic field reaches its maximum strength H ₀ when the capacitor battery 11 is discharged to the solenoid 5. In this case, the metal cumulative jet plays the role of a permanent magnet (core), which moves at a high speed (up to 20,000 m/s) inside the solenoid 5. In this case, the magnetic flux also changes and an electromotive force of induction arises, which is transmitted through the turns of the winding of the radiation circuit 6 to the vibrator 2 and radiated into space in the form of a powerful ultrashort EMP pulse [ 3].

During the operation of the device, in addition to the cumulative action of an air bomb, pulsed electromagnetic radiation (EMR) is formed that affects the ACS and electronic components of the target.
