Description

The invention relates to devices that convert the energy of an explosion into the energy of an electromagnetic pulse (EMP) of increased power to destroy enemy electronic equipment.

Currently, classic types of weapons are fading into the background; they are being replaced by new, high-tech weapons. Priorities are changing: the goal of future wars is not the population, but the enemy’s economy. Most combat missions will now be performed by robots - from unmanned aerial vehicles to automatic armored vehicles. Therefore, electromagnetic, or, as it is also called, microwave weapons, come to the fore, burning out the computer “brain” of the enemy. The first electromagnetic munitions were and remain conventional nuclear charges, one of the damaging factors of which is an electromagnetic pulse that disables electronics for many kilometers around. The effect of electromagnetic radiation turned out to be so effective that there was immediately a desire to create non-nuclear electromagnetic weapons. The first thought that comes to mind is directed radiation, which travels about 40 thousand times faster than a ballistic missile warhead flies. Such a gun will not require shells, it will have no recoil, and its firing is silent and smokeless. Simple calculations show: the range of destruction of electronics cannot exceed the size of the radiation source by more than 1000 times, otherwise the radiation will cause a discharge in the surrounding air and all its energy will be spent on the formation of a plasma screen. It follows from this that sources of narrow beams of electromagnetic radiation - microwave guns - will always be inferior to artillery systems of equal size in terms of range and effectiveness of destruction. The radiation beam cannot be made to bend, so you cannot shoot from closed positions. If we add to this the considerable dimensions of microwave guns, it is clear that they have no chance on the modern battlefield. The list of shortcomings goes on. But this does not mean that electromagnetic weapons have no future.

It’s another matter if the EMP source is triggered near the target - then the advantage over the shock wave or fragments is obvious. For example, the radius of destruction of a cruise missile with 120-mm electromagnetic ammunition can be 60 meters (the same thousand radii of ammunition), which is ten times further than with a high-explosive fragmentation projectile of a similar caliber.

However, at the moment there are no compact high-density electromagnetic energy storage devices in the world that could be placed inside modern ammunition. Therefore, to generate it, a traditional explosive is used, the detonation of which releases thousands of times more energy than the best battery of the same volume can deliver to the load. Such generators are called explosive-magnetic, and they again owe their birth to nuclear weapons. The phenomenon of EMR generation during the explosion of charges of condensed explosives (HE) is quite well known and described in the scientific and technical literature [1, 2].

In practice, such devices that ensure the conversion of explosion energy into the energy of an electromagnetic pulse have found application, although limited. Thus, explosive magnetic-cumulative (MC) generators are known [3], used to produce powerful electromagnetic pulses.

An explosive magnetic-cumulative generator is known (patent RU No. 2044252 from 1995) [4], containing an explosive charge, an external magnetic field solenoid, internal and external electrodes and an insulator, it is also equipped with an additional electrode placed in the charge along its axis and electrically connected with internal and external electrodes by means of an adjustable resistance.

The main disadvantages of this device, which limit the use of these generators as energy sources, are the relatively low current and energy amplification factors. This is due to a number of reasons, the main ones of which are large losses of magnetic flux due to the relatively long compression time.

An explosive magnetic generator is also known (patent RU No. 2516260 of 2020) [5], containing a deformable cylindrical spiral connected to a power source, a return current conductor placed coaxially inside it in the form of a pipe with an explosive charge, an inductive load and a closing key, connecting the deformable spiral and the pipe, and located outside the deformable spiral on the side opposite to the load, and the deformable spiral is made in the form of a multi-start spiral with an even number of starts, while all the starts in each of these spirals with even and, accordingly, odd serial numbers are connected in parallel with the formation in each of the spirals of two parts equal in size and electrically isolated from one another, at the same time, one of the free ends of the deformable spiral is connected to the other end of the pipe, and a load is connected to the second free end of the deformable spiral, the deformable spiral consists of two coaxial , located above each other and inductively coupled parts, while the lower spiral is completely deformable (completely deformable) and forms the working cavity of the generator, while the upper spiral forms a partially deformable zone for transforming the magnetic flux from the working cavity of the generator into an inductive load, while all entries of the completely deformable lower spiral are included in accordance with each other, and entries with even and odd numbers of the partially deformable spiral of the magnetic flux transformation zone are connected opposite each other in such a way that the partially deformable spiral forms a two-layer structure of an even number of elements with counter magnetic fluxes in in all directions; at the same time, the odd runs of the fully deformable spiral and the odd runs of the partially deformable spiral are connected in series and in accordance with each other, while the even runs of the fully deformable spiral and the even runs of the partially deformable spiral of the transformation zone are connected to each other and the inductive load in series, while the completely deformable spiral with even entries and a partially deformable spiral also with even entries are included counter to each other.

The disadvantages of the device include the complexity of the design, which uses partially deformable and deformable spirals connected to each other by leads with even and odd numbers, respectively.

For the effective use of EMP, it is necessary to deliver an explosive generator of electromagnetic pulses as close as possible to the target and far enough from its radio-electronic equipment to prevent their destruction. In our opinion, this task is best accomplished by a multiple launch rocket system, delivering ammunition to the point of use with high accuracy and minimal physical impact.

There is a known method of hitting a target with a rotating ballistic rocket projectile (RU patent No. 2158411 of 2000), the launch or flight of the projectile is carried out with stabilization by the roll of its head compartment, equipped with a homing head and connected to the remaining compartments of the projectile through a cylindrical hinge.

This method helps to accurately hit a target only due to high-explosive and fragmentation effects.

The closest in technical essence to the claimed invention is Staroverov's fragmentation ammunition (options) and a device for its use (options) (patent RU No. 2472098 of 2013), containing an explosive charge and a fragment-forming jacket mounted on bearings on the shaft and has inclined aerodynamic surfaces that cause it to rotate relative to its longitudinal axis. The ammunition consists of two parts rotating in opposite directions.

The disadvantage of this device is the use of only fragments and high-explosive ammunition to destroy objects.

The objective of the invention is to create a device capable of damaging electronic components of enemy weapons and technical equipment with an electromagnetic pulse, inflicting physical damage with high-explosive and fragmentation effects of ammunition that has uncharged power sources during storage, transportation and launch.

The technical result of the proposed type of ammunition is the expansion of its combat capabilities by type of destruction, increasing the effectiveness of destruction of enemy weapons and technical equipment, safe storage and transportation.

The required technical result is achieved by the fact that the rocket consists of two connected parts containing an explosive charge - the bow and stern rocket, equipped with inclined aerodynamic surfaces that cause these parts of the projectile to rotate relative to its longitudinal axis in opposite directions. The projectile is equipped with an electric generator containing a rotor and a stator, the stator of the electric generator is located in the bow, the rotor of the electric generator is fixed in the aft rocket part of the projectile and connects the bow to the aft rocket filled with high-pulse charges of mixed solid fuel. In the nose part of the projectile there is an explosive magnetic generator connected to the electric generator through a capacitor battery, which is charged by the electric generator after launch, an antenna configured to propagate an electromagnetic pulse from the explosive magnetic generator, and a control system unit, while the inclined aerodynamic surfaces are foldable.

The essence of the invention is illustrated by the drawing, where in FIG. 1 shows a rocket, which includes:

1 - antenna;

2 - electric generator rotor;

3 - aft missile unit;

4 - aft aerodynamic surfaces;

5 - bow aerodynamic surfaces;

6 - electric generator;

7 - bow.

In FIG. Figure 2 shows a diagram of the nose of the rocket, where:

I - antenna;

5 - bow aerodynamic surfaces;

6 - electric generator;

7 - control system block;

8 - capacitor battery;

9 - explosive magnetic generator;

10 - electric detonator.

In FIG. Figure 3 shows a diagram of an explosive magnetic generator, where:

II - housing of the explosive magnetic generator;

12 - copper winding;

13 - explosive charge;

14 - copper tube.

The invention works as follows: the rocket is loaded in the established order into the launcher of the multiple launch rocket system and transported to the launch site. The ammunition's power supply system is discharged for safe storage and transportation, preventing abnormal firing.

After launch, the rocket leaves the guide, the folded bow aerodynamic surfaces (5) and the stern aerodynamic surfaces (4) open, causing the bow part (7) and the stern missile part (3) to rotate relative to its longitudinal axis in opposite directions.

The projectile is equipped with an electric generator (6) containing a rotor and a stator. Moreover, the stator of the electric generator is located in the bow part (7), the rotor of the electric generator (6) is fixed in the aft missile part (3) of the projectile and connects the bow part (7) with the aft missile part (3). In the nose part (3) of the projectile there is an explosive magnetic generator connected to an electric generator (6) through a capacitor bank (8). The electric generator (6) charges the capacitor bank (8) during the flight.

When choosing targets to hit using this missile, it is necessary to take into account the time and, accordingly, the distance required to fully charge the capacitor bank (8) with the electric generator (6). Accordingly, before launch, the calculated flight parameters are entered into the control system (7), taking into account the coordinates of the target, the time required to fully charge the capacitor bank (8), the flight altitude for the effective use of the damaging effects of the explosive magnetic generator (9) and the moment of initiation of the electric detonator (10) .

An instant before the detonation of the explosive charge (13) located in the copper tube (12) after initiation of the electric detonator (10), the current from the capacitor bank (8) enters the copper winding (12) and creates a magnetic field. The detonation of the charge propagates from the rear end of the copper tube (14) to the front. The expanding copper tube (14) touches the edge of the copper winding (12) and creates a moving short circuit. The moving circuit compresses the magnetic field and at the same time reduces the inductance of the winding.

As a result, the explosive magnetic generator (9) creates a rapidly growing current pulse, which is interrupted before the final destruction of the device. According to published results, the rise time is tens or hundreds of microseconds, and the peak current value is tens of millions of amperes. Compared to the power of the generated pulse, a lightning discharge looks like a photo flash.

An electromagnetic pulse through an antenna (1) configured to propagate an electromagnetic pulse from an explosive magnetic generator strikes enemy electronic equipment in the affected area.

The missile will make it possible to destroy enemy electronic weapons - a universal means for destroying both airborne, mobile and stationary objects. Allows you to destroy radio-electronic weapons with high

noise immunity using special devices for protection against energy overloads operating in passive mode. Its use contributes to the disablement of various objects containing radio-electronic elements, including detection and communication equipment, weapons systems, vehicles, etc.
