Method for protecting against unmanned aerial vehicles

Abstract

The invention relates to technologies for countering unmanned aerial vehicles. A method for protecting against unmanned aerial vehicles entails attacking the optical equipment of the surveillance system of a malicious unmanned aerial vehicle (UAV) with a special liquid. The special liquid is used to soil the lenses of the optical equipment of surveillance systems as a UAV travels through a cloud of aerosol in which said liquid constitutes the dispersed phase. To generate a cloud of aerosol, aerosol cloud generating devices are used which are disposed on UAVs used as interceptors. An intercepting UAV is positioned below a malicious UAV and a cloud of aerosol is generated in an upward direction. The technical result of the invention is that of providing increased anti-UAV protection to protected objects.

[0001] PROTECTION METHOD

[0002] FROM UNMANNED AERIAL VEHICLES

[0003] DESCRIPTION OF THE INVENTION

[0004] Technical area.

[0005] The invention relates to air defense systems and can be used to protect against unmanned aerial vehicles (hereinafter referred to as UAVs).

[0006] It is known that BILAs are equipped with observation systems, including optical instruments, by means of which they carry out aerial reconnaissance or targeting for dropping explosives or ramming (the so-called “kamikaze UAVs”),

[0007] Prior art.

[0008] A known method of protecting objects, including from aircraft, involves setting up smoke screens using devices installed on aircraft (Kotelnikov V. Soviet aviation smoke devices of the 1930-1940s / / Aviation and Cosmonautics. - 2013. - No. 2) or on aircraft capable of zero horizontal flight speed (https: / / www. youtube. com / watch?v=8R7nWFJy3cc, published 01 / 25 / 2022). Smoke (aerosol) generators were installed, for example, on the P-S reconnaissance aircraft, the TB-3 bomber, and the Mi-2X helicopter.

[0009] The disadvantages of the known solution include the creation of optical interference not only for enemy UAVs, but also for one's own units: in a smoke screen, everyone sees equally poorly.

[0010] An unmanned aerial vehicle-interceptor is known (taken as a prototype), made in the form of a free-standing monoplane, including a fuselage in which weapons in the form of a rifle complex are placed along the axis passing through the center of mass of the aircraft (patent RU 2699148, published 09 / 03 / 2019. Bulletin No. 25).

[0011] The disadvantages of the known solution include the impossibility of capturing an enemy (intercepted) aircraft in working order when it is implemented.

[0012] Technical challenge.

[0013] The technical problem that the proposed invention is aimed at solving is to increase the effectiveness of air defense (AD) in the anti-UAV segment.

[0014] The technical result of the invention is to increase the security of protected objects from UAVs.

[0015] Moreover, when using such means, unlike, for example, firearms, the attacking UAV will not suffer significant damage, which is also an additional technical result (the UAV can be used in the future, for example).

[0016] Solution to the problem.

[0017] The solution to the technical problem is achieved through the combined application of the following measures:

[0018] - disabling optical devices of surveillance systems installed on UAVs by applying a layer of a special liquid to their lenses, which constitutes a liquid dispersed phase of an aerosol placed in the form of a cloud along the UAV’s course,

[0019] - the use of counter-UAV installations, which are used to create aerosol clouds placed on unmanned aerial vehicles used as interceptors.

[0020] An aerosol cloud may be created, for example, but not exclusively, by means of a remotely initiated explosion of a projectile with an appropriate filling or by firing a jet of liquid at a UAV, which forms a cloud of liquid particles near the aircraft.

[0021] The dispersion of the aerosol cloud, the chemical composition and the method of formation are the subject of protection under this application.

[0022] A special liquid, the droplets of which make up the dispersed phase of an aerosol placed in the form of a cloud along the UAV's course, and settles on the lenses of the UAV's surveillance systems, creating optical interference that reduces the quality of the image obtained through these lenses.

[0023] For example, but not exclusively, products of processing of vegetable and animal oils, oil and its processing products: drying oil, new and used motor oil can be used as a special liquid.

[0024] It is preferable to use solutions of chloroprene rubbers in gasoline or toluene, alcohol solutions of epoxy polymers, liquid acrylic and alkyd paints as special liquids.

[0025] The choice of a special fluid is based on the optimal fulfillment of three requirements:

[0026] - the ability of a liquid to disperse in a gas (air) dispersion medium,

[0027] - the ability of the liquid to contaminate the lenses of surveillance system devices and

[0028] - adhesion of liquid to lens glass.

[0029] In the context of this application, counter-UAV systems used to generate aerosol clouds are understood to mean systems for generating the aforementioned aerosol clouds, located on a mobile platform. The use of mobile platforms (UAVs) allows for a rapid response to emerging threats and, in particular, the timely relocation of the systems used to generate aerosol clouds closer to the potential emergence zone of the UAV (allowing for a more rapid response to the detection of UAVs).

[0030] The firing sector (angle) can be increased (ensured) by rotating the horizontal plane of the part of the installation where the hole (holes) through which the aerosol cloud (or the entire installation) is ejected is located, or by ejecting ammunition to create an aerosol cloud.

[0031] To increase the firing sector, the UAV can perform single or continuous oscillations of the nose in the horizontal and / or vertical plane (which will increase the likelihood of effective counteraction to the attacker's UAV).

[0032] Preferably produce continuous rotation (with the appropriate angular velocity - the higher the speed, the greater the likelihood of effective counteraction to the UAV).

[0033] Description of embodiments.

[0034] The method of protection against UAVs proposed as the present invention is carried out in the following order.

[0035] 1. Detection of UAVs in a protected area (within which the protected object is located) is carried out, determining the flight altitude, speed, and course of movement.

[0036] Detection of UAVs is carried out by any method known from the state of the art, for example, but not exclusively, by radar, acoustic, visual, by direction finding of the UAV information channel, etc.

[0037] Detection of UAVs is carried out by any method known from the state of the art: for example, but not exclusively, by radar, acoustic, visual, by direction finding of the UAV data channel, etc.

[0038] For example, to solve such problems, the SkyScope drone detector can be used, which can determine the type and location of the most common drones at a distance of up to 7 km (direction finding, radar, visual) 1 ^Djistor.ru / goods / Komplekt- SkyScope-dlya-obnaruzheniya-i-blokirovki-BPLA-radius-obnaruzheniya-7- km).

[0039] Determination of the flight altitude, speed, and course of the UAV is carried out by any method known from the prior art using the appropriate physical effects and technical means.

[0040] 2. Create an aerosol cloud in the area of ​​movement of the detected UAV, taking into account the required lead value corresponding to the speed and course of the UAV, formed by droplets of a special liquid.

[0041] The UAV carrying the counter-UAV system, depending on the possibility of the direction of aerosol cloud creation, can occupy different positions relative to the enemy UAV (being above the attacker’s UAV, then the direction of the aerosol cloud is downwards; being under the UAV, then the aerosol cloud is downwards, etc.).

[0042] It is preferable to create an aerosol cloud from the bottom up, then the interceptor UAV should be located under the attacker UAV and the direction of the aerosol cloud should be directed upwards - in most cases, the location of the camera of the attacker UAV will be below.

[0043] The aerosol cloud through which the UAV flies contaminates the optical devices of surveillance systems, thereby "blinding" the UAV. An important feature of the proposed method is that it does not create optical interference for personnel operating the facilities that need to be concealed from the UAV. Since modern UAVs of any type are typically smaller than the objects requiring concealment (fortifications, troop columns, equipment and personnel in concentration areas, etc.), blinding the UAV is simpler and, obviously, less expensive than creating large-scale smoke screens in the area of ​​protected land and water facilities. This circumstance increases the likelihood of successful concealment of the aforementioned objects and, thus, contributes to their increased security from aerial reconnaissance and / or attack, thereby achieving the first stated technical result.

[0044] A "blinded" aircraft essentially becomes uncontrollable, but otherwise remains operational and can be forcibly landed (captured). This suggests the possibility of achieving the second stated technical result.

[0045] Each counter-UAV installation can be equipped with its own PC or FPGA.

[0046] Control (sending the action command, as well as time, vertical, and horizontal sectors) can be performed from a central control panel (also available as a PC). This requires a wired and / or wireless connection between the unit(s) and the control panel (this can be a PC-based connection, or the connection can be established via modems).
