Description

Field of technology to which the invention relates

The invention relates to the field of creating protective formations that ensure the stable functioning of group objects in the event of destructive effects on them of weapons in the form of aircraft used from various heights.

State of the art

Group objects can be exposed to several types of man-made, natural and other destructive factors, which include shock wave, thermal, as well as mechanical effects on them from bodies of different sizes.

In some cases, the external destructive factor affecting group objects is aircraft, as a means of destruction, or their carriers.

There is a known method of destroying an unmanned aerial vehicle, the essence of which is to continuously supply dye under pressure with overlapping across the width of the zone of intersection of the trajectory of the aircraft, forming a stable adhesion with external surveillance devices and/or glazed openings for visual control (Patent for the invention “Method of defeating a high-speed aircraft apparatus" RU 2162997 C1, F41H 11/04, F42B 12/36, 08/10/1999).

Patent for the invention “Method of functional suppression of an unmanned aerial vehicle” RU 2700207 C1, V64S 99/00, N04K 3/00, F41H 13/00, F42B 12/36, 09.13.2019).

The disadvantages of this method are: the complexity of the system, the impossibility of using the system on high-altitude flight paths of aircraft, the need to lay the system along the entire protected perimeter, and taking into account the need to place the system at a safe distance from the protected object, the size of the system will be measured in kilometers.

There is a known method of functional suppression of an unmanned aerial vehicle, the essence of which is to increase the probability of destruction of an unmanned aerial vehicle through the sequential use of three damaging factors. To do this, a functional suppression container is delivered to the flight area of the aircraft at a distance of 50-100 meters from it, which, when approaching the target, generates a series of ultra-short microwave radio pulses in the frequency range 0.5-10 GHz towards the unmanned aerial vehicle for its functional suppression up to complete discharge of the power supply (the first damaging factor), while the container contains a self-destruction charge, which, after exposure to the first damaging factor, self-detonates the system at a distance of 50-80 meters from the affected aircraft, resulting in the formation of a cloud of dye (the second damaging factor) and the field of damaging mechanical elements of the power supply and microwave generator (the third damaging factor), which, when exposed together, lead to either physical damage or destruction of the unmanned aerial vehicle (Patent for the invention “Method of functional suppression of an unmanned aerial vehicle” RU 2700207 C1, B64C 99 /00, Н04К 3/00, F41H 13/00, F42B 12/36, 09/13/2019).

The disadvantage of the system is the complexity of the design, small radius of destruction, low probability of damage in the event of high speed of the aircraft.

The closest in technical essence (prototype) to the proposed invention is a method of protecting a group object from weapons of destruction (Patent for the invention “Method of protecting a group object from weapons of destruction” RU 2776004 C1, F41H 11/00, 01/26/2022).

The technical result in this method of protecting a group object, which includes the protection of particularly important elements of the object, is achieved by creating a protective curtain by bringing emission generators to a given height, their subsequent instantaneous depressurization, the formation of a front of overlapping two-phase volumetric dispersed and sticky aerosol formations that settle and prevent successful passage aircraft to the target at different altitudes, promoting the adhesion of particles of a dispersed formation on the body of the aircraft, accompanying the deterioration of the aerodynamic characteristics of the aircraft.

This method of protecting a group object has a significant drawback, which is that its implementation provides only a pulsed effect formed by a protective screen from a dispersed formation directly on the structural elements of the aircraft and deterioration of its aerodynamic characteristics.

Thus, the protection methods discussed above, which make it possible to create artificial protective formations, do not completely solve the problem of ensuring the protection of a group object from the destructive effects of weapons in the form of aircraft used from various heights.

Disclosure of the invention

In order to solve the problem of protecting a group object from weapons in the form of aircraft operating simultaneously at different altitude ranges, a new method of forming a barrier formation, which has new properties, is proposed.

These properties include the dissipativity of the protective curtain, which makes it possible to disable the optical instruments of the aircraft, as well as increasing the probability of detecting the aircraft due to the adhesion of fluorescent particles to structural elements.

The technical result of the proposed method of protection is achieved by forming a protective screen by sequentially placing dispersed and fluorescent aerosol formations in order to disable the optical means of the aircraft and increase the likelihood of its detection by the optical method.

Carrying out the invention

For reliable protection of the group object 3, the ejection barrels 4,5, at the command of the control system 6 (Fig. 1), ensure the ejection of containers 7 equipped with generators 8 to a height exceeding the flight path of the aircraft (Fig. 2). The generators exit the container alternately in the direction of movement of the container (Fig. 2), which makes it possible to increase the depth of the protective screen. Thus, fluorescent aerosol 11 and dispersed 12 protective screens are sequentially created in the direction of the possible flight of the aircraft in several echelons along the front and in height with overlapping zones of protective formations in order to form a protective screen.

The dispersed curtain 9 is obtained by spraying particles, and the aerosol curtain 10 is obtained by spraying fluorescent liquid. An aircraft moving towards an object first overcomes a fluorescent aerosol screen and then a dispersed screen.

In the process of flying through the fluorescent aerosol screen 11, the body of the aircraft is painted with a fluorescent liquid, which increases its visibility for simpler systems and detection methods, in the event that the aircraft overcomes a dispersed protective curtain.

Timely construction of protective screens is ensured by the operation of the control system 6 and is achieved by sending a signal to eject the barrels of containers 7 equipped with generators 8 for the purpose of constructing protective screens 11 and 12 (Fig. 3).

Ejection barrels 4 and 5 operate using the principle of mortar throwing. Overpressure is used to eject containers from generators to a given height.

At a given height, explosive depressurization of the generators occurs and dispersed and fluorescent aerosol formations are released from them, respectively (Fig. 3).

Subsequently, due to a decrease in the speed and intensity of the expansion of formation particles, the formed medium settles at a calculated rate.

The technical task of influencing a protective dispersed formation on aircraft is accomplished by forcing it to overcome protective screens.

The spent capsules of generators 13, after completing the task, fall to the earth's surface in the position area and can be used repeatedly.

If an aircraft overcomes a protective barrier, the probability of its detection increases significantly, since the aircraft will be marked with a fluorescent liquid.

To increase the duration of the active impact on the aircraft, it is possible to repeatedly activate the protection system along the trajectory of the aircraft when using the capabilities of the control system.

Thus, the proposed method of protecting a group object with a two-phase dispersed formation provides a technical result consisting in protecting the group object from the destructive effects of weapons in the form of an aircraft.
