Description

The invention relates to methods for preventing the penetration of enemy reconnaissance, attack and defeat using airborne or in the aquatic environment, made of strong and lightweight material, barriers and can be used in peacetime to prevent terrorist penetrations of unmanned aerial vehicles into a controlled territory with the aim of conducting reconnaissance or terrorist attack, and during the conduct of hostilities when the enemy commits reconnaissance flights using unmanned aerial vehicles missile launchers (UAVs) and striking targets with unmanned guided self-propelled weapons of destruction (BMSSP) (guided missiles, torpedoes, shells, bombs, etc.).

Currently, in the field of armaments, in addition to classical weapons, such as bullets, shells, bombs, mines, etc. there are unmanned guided self-propelled weapons of destruction, which include guided missiles and torpedoes, guided bombs and shells. These means of destruction are widely presented for work in all environments - both in air and on land, water and under water.

The main feature and scope of these means of destruction is the very high accuracy of hitting at considerable distances in difficult conditions.

Existing methods of dealing with this kind of means are aimed both at destroying them, and at setting various obstacles that knock them off course.

However, for various reasons, the effectiveness of the fight against such funds is not sufficient to ensure high security of protected objects.

So, for example, to destroy a BSSSP, a whole complex of measures is required to detect it, calculate its characteristics, identify false targets, combat interference, and have the means of control (for example, anti-missiles, anti-torpedoes) in the right place in the right amount and type, pointing them at the target , launch and ensure a high probability of destruction of the target.

When interfering, it is necessary to have the necessary means for this and it is also impossible to guarantee a 100% result, moreover, BSSSPs usually have anti-interference systems.

All this makes the protection against BUSSP very difficult and expensive, especially when they are mass-launched and work on many different goals.

Also, UAVs, which are increasingly used by terrorists and protection against which is still insufficient, pose an ever greater danger.

The developed method offers an additional possibility of protection against the BSSSP and UAV

There is a known (RU, patent 2639298, publ. 22.12.2017) method of anti-torpedo protection of a surface ship or submarine using an underwater transporter having an instrument compartment with control devices, a cargo compartment, a compartment with a power plant and a compartment with controls and propulsion. The transporter is additionally equipped with a container with a network trawl, tension and contact devices, a current source, a gas generator and an inflatable chamber, the conveyor’s movement is controlled towards the detected enemy torpedo, for which they enter the route of its movement into the control devices, the network trawl is made of durable, flexible material and laid in a container fixed in the rear of the transporter, the container is separated from the conveyor after exiting the launcher of the underwater ki or after water splashdown when using from a surface ship, with the help of a tension device, the trawls are attached to the rear of the conveyor, the container cover is opened and the trawl is pulled out due to the force of the incoming water flow, bringing the trawl to an extended position, the spring of the tension device is regulated by the value of the hydrodynamic resistance force trawl, the gas generator is launched in the case of mowing the enemy torpedoes and exceeding the spring tension force above the calculated value using the contact device An air vessel connected to a current source is filled with gas in an inflatable chamber located in the recess of the transporter’s body, gives the transporter positive buoyancy and changes the resulting force acting on the enemy’s torpedo due to the counter-drag of the transporter and its positive buoyancy, changes the trajectory of the torpedo and moves it to the side from a surface ship or submarine, the place of the spent torpedo is designated with the help of signal devices that activate when the Comp act device.

The disadvantage of this method should recognize its complexity.

It is known (RU, patent 2197701, publ. 27.01.2003) a fence device that contains a system of balloons, cables holding balloons at a height of 120 ... 150 m, a thin nylon network with cells 1.0 ... 1.3 m, located between the balloons, and anti-personnel fragmentation mines fixed between the grid nodes, as well as regular aerosol means mounted on a nylon grid, and a control system for launching aerosol means.

The disadvantage of this analogue is that the probability of defeating air attack means does not fully satisfy the requirements for survivability of the protected object, since even with low speeds of approach due to the inertia of the fire of anti-personnel fragmentation mines (NOM), enemy air attack means can go away with a high probability outside the affected area with fragments.

It is known (RU, patent 2273818, publ. 10.04.2006) a barricade device containing barrage balloons, cables holding balloons at a height of 120 ... 150 m, a thin nylon network with cells 1.0 ... 1.2 m, light anti-personnel fragmentation mines actions fixed between the nodes of the grid, the grid-sensor for detecting enemy air attack means, in addition, it is additionally equipped with active protection means installed evenly between the nodes of the grid-sensor, and a detection radar placed on a cable that connects the aerostat you.

The known device operates as follows.

In advance, in a threatened period, install the proposed device in front of the protected object. When approaching the enemy’s air attack means towards the object, the remote launch system launches aerosol means, which form a vertical aerosol curtain in 30 ... 40 s, as a result of which the probability of detection of the protected object is reduced. When approaching enemy high-speed air attacks (70-700 m / s) at a distance of ~ 50 meters, a detection radar detects targets and, after 0.07 s, shoots active means that form a bunch of damaging elements to destroy the target. If the enemy’s air attack means overcome the auxiliary nylon network (sensor), then anti-personnel fragmentation mines mounted on the main grid are triggered.

A disadvantage of the known technical solution can be recognized as its complexity and, therefore, low reliability.

The specified decision was taken as the closest analogue.

The technical problem solved using the developed method is to improve the defense capabilities of civilian and military installations.

The technical result achieved through the implementation of the developed method is to increase the protection of objects from impact by unmanned controlled self-propelled means of destruction and attack of unmanned aerial vehicles and their means of destruction.

To achieve the specified technical result, it is proposed to use the developed mobile active device to protect various objects from unmanned controlled self-propelled weapons. The developed device contains at least a network made of mechanically strong and lightweight materials, aero / hydrostatic means fixed at the edges of the network, containers filled with compressed gas and placed with the possibility of controlled gas supply to the indicated aero / hydrostatic means, network deployment means in space (both external and internal, for example, using the inertia of the existing mass (gas cylinders) to deploy the network), as well as device controls with the necessary sensors (possibly oak ation of critical components). All this is preferably compactly packed in a cowl sleeve.

It is desirable that in the manufacture of the developed device light and mechanically strong materials be used. In particular, the network can be made of aramid or flexit monofilaments.

The network can be made using materials reflecting various types of signals used to direct unmanned guided self-propelled weapons. In particular, materials that absorb electromagnetic radiation (the so-called radio-absorbing materials) and absorb or reflect optical radiation, in particular boron nitride.

As means of aero / hydrostatics, hollow elastic tanks (rubber chambers such as cameras from sports balls) are used, inside which there is no liquid and / or gas medium. Compressed gas cylinders are connected to the inlets of the said elastic reservoirs and are connected with the possibility of an adjustable supply of compressed gas to the elastic reservoir. As the filler of the cylinders can be used hydrogen, helium, natural gas, air.

In some versions of the implementation of the developed technical solution, depending on the area of its application, the networks can be used to protect watercraft and water areas — devices of the “Gnome” type (https://gnomrov.ru/about/articles/gnom-family) or type "Harpsichord-1P" (http://forums.airbase.ru/2011/07/t54451), the same network can be self-propelled.

When protecting ground objects (for the air), engines used in rocket models can be used as a delivery vehicle.

The developed device may additionally contain a sleeve (case) intended for transportation and storage of the network, while the sleeve may contain (alternatively, on the sleeve attached) means for delivering the network to the deployment point.

In some embodiments, the Device may additionally further comprise a common sleeve, which contains several stand-alone devices with their sleeves.

On the network can be additionally fixed means of destruction / detention / change of course of unmanned guided self-propelled weapons of destruction. These can be explosive packets, anti-personnel mines, generators of electromagnetic or acoustic radiation, magnetic cumulative charges, etc.

The device may further comprise means for launching from a mortar or gun barrel, a hand grenade launcher, as well as launch means specialized for the protected object. Before starting, the device is turned on (for example, automatically at startup, by pulling out checks, by pressing a button, etc.). During the start-up, operation parameters can be transferred to the device, for example, deletion on which disclosure is performed, supported height / depth, operating time, etc., or standard settings can be used.

To protect objects in an underwater environment, the following method of use is possible:

When an attack is made on a target of a BPSPP, a device with a sleeve containing a delivery device (for example, a screw or gas engine for self-starting or launching from a torpedo launcher, or a charge of gunpowder for launching from a gun) is fired at its side using a launch device, while the control device is introduced response parameters (e.g. range and depth).

Upon reaching the specified conditions, the sleeve and the cowl are reset, the reservoirs are filled and the network opens. If the BUSPP enters the network, it will be neutralized by detonation or off course.

In the case of protection of ground objects, the device can be used as follows.

If an unmanned controlled self-propelled means of destruction or UAV is detected in the air near the guarded object, a device having a sleeve with launching means (for example, a rocket engine for launching from, for example, a grenade launcher, or a powder charge for launching from a gun or mortar) is launched towards the danger by the security service (or automatically ), at the same time, the operation parameters are entered into the control device (manually, automatically or in advance). When the specified parameters are reached, the sleeve and fairing are reset, the network is deployed due to the action of the mass of compressed gas cylinders and reservoirs filled with compressed gas (or in another way). When an unmanned controlled self-propelled means of destruction or UAV gets into the network, a section or the entire network is fixed on its body. Depending on the configuration of the device, an unmanned controlled self-propelled means of destruction can be blown up, off course, lowered to the surface or neutralized by any known method. For example, in the event that powder propellant rocket engines with jet direction sensors are installed on the network, these engines can be turned on at the right time to divert the object off course to neutralize a captured object (to knock it off course). Also, the network can get into the control units of the BUSPP and damage or block them.

Also, an object can be off course using signal-reflecting materials, or traps (for example, thermal or reflecting radio signal / laser beam) that can be part of the network.

A feature of this device is the ability to "barrage installation" ie start-up without a target, “just in case” and, due to the ability to hover and maintain height / depth in both air and water, the device can block a given area for a specified time, including as a source of interference for the ACS and UAV . After the specified time, if the device does not catch an object, it blows off aerostatic balloons and falls to the ground (or inflates them and pops up, for the aquatic environment) - in this case, it can be picked up and reused. In such a barrage way, for example, by launching several networks at different heights and ranges, it is possible to cover a large area, protecting the object from a threat, without even using warning information systems (for example, radars).

Another important feature of the device is the possibility of hovering at any given angle relative to the ground due to the difference in gas volumes of the supplied aero / hydrostatic means. This allows you to overlap the entire hemisphere around the protected object. The required angle can be set at startup.

It is also important to note that the device may not use the explosion to destroy the target, but may lead or lead it off course. This allows it to be used in cases where the detonation is undesirable or dangerous for the protected object itself (for example, in cities, or for the protection of non-military objects - transport / civilian ships or aircraft passing in dangerous zones or attacked by terrorists).
