Description

Barrier device refers to air barriers designed to protect critical objects from enemy air attack means (AED).

The survivability of an object depends on the characteristics of the means of destruction and detection, their resistance to the effects of damaging factors, as well as external conditions, in particular, the nature of the spread of damaging factors.

For practical calculations, the following dependence is used to determine the survivability of an object:

Q _about = (1-P _obn ) (1-P _dec ) (1-P _vsp ),

where R _obn , R _rasp and R _vsp - the probability of detection, recognition and exposure to means of destruction of the enemy, respectively.

To achieve the required survivability of an object, it is necessary to minimize the value of these probabilities.

Known device barriers [1], which contains a barrage balloon, cables holding the balloon at a height of 120 ... 150 m, a thin nylon network made in the form of a truncated trihedral pyramid, with cells of 1.0 ... 1.2 m, light anti-personnel fragmentation mines directed action, air attack detection sensors.

The disadvantage of this analogue is that at high speeds the enemy’s HEV due to the relatively long response time of the POM detonation system, the likelihood of damage to air attack systems is significantly reduced.

The closest in technical essence to the proposed device is a barrage device [2], which contains a system of balloons, cables holding balloons at a height of 120 _... 150 m, a thin nylon network with cells 1.0 ... 1.2 m, located between the balloons, light directional anti-personnel mines fixed between the grid nodes, standard aerosol means fixed between the grid nodes, a remote control system for launching aerosol means, an auxiliary thin nylon mesh with cells 1.5 ... 2.0 m, Thoraya fastened at the top of the main grid 45 ... 60 ° thereto, while the lower part - on the surface, the active protection means arranged uniformly between grid sensor nodes detect radar with an overview of the space in the sector 220 ... 270 °.

The main disadvantages of this analogue are:

the proposed regular aerosol means provide masking of the object only in the visible spectrum (0.4-0.76 microns) and do not provide masking in the infrared and radar ranges, in which homing heads of modern air-defense devices work;

the efficiency of closing the object with an aerosol curtain is not ensured, the formation time of which is about 30 seconds, and the time from the moment of aiming UAB, UR to the defeat of the object is 18-25 seconds;

The required technical result, which consists in reducing the likelihood of detecting and recognizing an object, reducing the time for placing an aerosol curtain, increasing the duration and area of smoke, is achieved by the fact that the device contains a quick system for placing aerosol curtains (SBPAZ) installed on the ground around the perimeter of the protected object, and a radar early warning (L _о = 20 km), installed in the upper part of the cable, holding the balloon.

The proposed device allows you to mask the object in the wavelength ranges of 0.4-14 microns, the formation time of the aerosol curtain is not more than 5 seconds. The firing range of aerosol forming agents is 50-60 m, which allows you to completely close the object of protection in all ranges of the GOS operation of aircraft air attack equipment.

Therefore, the claimed device meets the criterion of "novelty."

Until the filing date of the patent and scientific and technical literature, we are not aware of such a combination of essential features required to solve this technical problem, which indicates the inventive level of this technical solution.

The drawing shows a diagram of a protection device (side view - figure 1, top view - figure 2), which contains a balloon barrage (1), a cable (2), a radar for detecting short-range targets (3), a thin nylon network mounted on the surface of the earth at an angle of 30-60 ° (4), the main network fixed to the surface of the earth at an angle of 30-60 ° (5), radar for early warning of targets (6), active protection equipment (7), target detection sensors (8) , fragmentation mines of directional action (9), a system for quickly placing aerosol curtains (10).

The evidence confirming the feasibility of the invention is that the authors propose means and systems that are adopted.

The device operates as follows.

In advance, in a threatened period, install the proposed device in front of the protected object. Upon approaching the enemy’s IED in the direction of the object at a distance of 20 km, the long-range detection radar (6) sends a signal to the SBPAZ executive device, ammunition with an aerosol forming composition 51-42G is fired, which form an aerosol curtain in no more than 5 seconds. When approaching the enemy’s high-speed air attack means at a distance of 50 m, a short-range detection radar (3) detects targets and fires active means (7) that form a bunch of damaging elements to destroy the target, by analogy to the prototype.

In the event that the enemy’s SRH overcome the auxiliary nylon network (sensor), the POM installed on the main grid is triggered by analogy with the functioning of the prototype.

The 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 IED in the direction of the object at a distance of 20 km, the long-range detection radar (b) sends a signal to the SBPAZ executive device, ammunition with an aerosol forming composition 51-42G is fired, which form an aerosol curtain in no more than 5 seconds. When approaching the enemy’s high-speed air attack means to a distance of 50 m, a short-range detection radar (3) detects targets and fires active means (7) that form a bunch of damaging elements to destroy the target, similar to the prototype.

In the event that the enemy’s SRH overcome the auxiliary nylon network (sensor), the POM installed on the main grid is triggered by analogy with the functioning of the prototype.

Thus, the proposed device due to new significant features will reduce the likelihood of damage to the protected object.
