Description

Field of technology to which the utility model relates

The utility model relates to the field of weapons and equipment, to the development of camouflage uniforms and is intended to camouflage personnel from surveillance devices operating in the infrared range.

State of the art

For the purpose of detecting people and equipment in conditions of poor visibility or at long distances, thermal imaging surveillance devices are used, which record infrared radiation emanating from objects with a certain temperature, and night vision devices, which record infrared radiation reflected from objects. Since the temperature of a person and operating equipment differs from the ambient temperature, it is advisable to develop camouflage suits that shield infrared radiation.

The technical solution “Camouflage Cape” is known from the prior art (Patent RU 215862 MPK F41H 3/00 (2006.01) D03D 11/00 Camouflage Cape / Lebedev M.M. - No. 2022130037, declared 11/18/2022; published 12/30/2022; Bulletin . No. 1), consisting of several layers of sheet materials and fastening elements and containing a layer of padding polyester covered with top and bottom layers of polyester film with metal spraying, an outer layer of fabric with fastening tape and an inner layer of fabric with steel eyelets, Velcro and corner loops. The disadvantage of this solution is the inability to sufficiently camouflage moving parts of the body protruding beyond the camouflage cape. This drawback is eliminated by the presence of sleeves and mittens in the claimed utility model that cover the moving parts of the human body.

The technical solution “Transforming cape for personnel” is known (Patent RU 218914. IPC F41H 3/00 (2006.01) A41D 15/04 (2006.01). Transformable cape for personnel / Sulyan M.S. - No. 2023104691; announced 02.03 .2023; publ. 06.19.2023; bulletin No. 17), the essence of which is that the transforming cape is made in the form of a multi-layer flexible base, equipped with a hole for the head with a hood in the central part, fasteners and drawstrings for attaching the base. required shape, and handles. The base is in the form of a protective cover, made of waterproof raincoat fabric, filled with a filler of air-filled non-woven bulk fiber made of mineral mullite-silica wool, and there are zippers for fixing the halves together when used as a stretcher. The main disadvantage when using such a cape dynamically is the incomplete camouflage of the person under such a cape in the infrared region, which makes it easier to detect the person. The inventive technical solution additionally provides camouflage of a person's hands in motion, while to complicate detection, flaps are used that are overlapped and sewn to the suit.

The patent “Heat-reflecting camouflage suit” was taken as a prototype (Patent RLJ 218109. IPC F41H 3/00 (2006.01). Heat-reflecting camouflage suit / T.P. Mamedov - No. 2023100167; declared 01/09/2023; published 05/11/2023; bulletin. No. 14), having a three-dimensional structure, including a base and deforming elements of a pyramidal shape, where the base is made of metallized synthetic fabric and deforming coloring applied to it, and the deforming elements of a pyramidal shape are made with different thermal radiation coefficients. The disadvantages of this suit are expressed in the use of materials with fairly low infrared radiation reflectance coefficients of the order of 0.3-0.6 and 0.6-0.9, which reduces its effectiveness, as well as the lack of camouflage of the hands and head.

The above analogues do not sufficiently solve the problem of effectively masking a person from detection devices operating in the infrared region of the spectrum.

The claimed technical solution makes it possible to mask the hands and head in the infrared region of the spectrum through the presence in the suit of mittens and a hood made on the basis of a material containing heat-reflecting layers with reflectance coefficients in the infrared region up to 0.99 due to the use of a silver thin-film coating, which increases the effectiveness of human camouflage in the infrared range of electromagnetic radiation.

Disclosure of the essence of the utility model

The purpose of the utility model is to create a camouflage suit that provides highly effective camouflage of a person for a long time in the infrared range of electromagnetic radiation from thermal imaging surveillance devices and night vision devices.

The technical result of the described utility model is achieved by manufacturing the base of the suit, which is a loose cape, from a material that screens infrared radiation, has a three-layer structure due to layers of thin silver film applied to the base material on the outer and inner sides and provides highly effective camouflage in infrared region of the spectrum of electromagnetic radiation. Additional flaps are sewn over the entire surface of the suit base to improve the reflection of infrared radiation in various directions, simulating the movement of foliage, and belt loops for attaching additional camouflage objects (for example, branches, leaves). The flaps and belt loops are also made of infrared-shielding material.

The design of the cape includes free sleeves equipped with drawstrings with tightening cords for fixing on the arm, at the ends of which mittens are sewn, and a hood equipped with a button-shaped fastener at the front of the collar to cover the person’s neck, as well as a drawstring made along the open edge , with a tightening cord to adjust the open surface of the face. The duration of camouflage in the infrared range is ensured by ventilation of the internal volume of the suit using a zipper provided on the side of the cape.

As a material that screens infrared radiation, for the manufacture of the base of the suit, Material that masks from thermal imaging surveillance devices is used (RF Patent Application No. 2023123506. D03D 15/52 (2021.01) D03D 15/553 (2021.01) D03D 15/547 (2021.01), which is due to its strength simultaneously with water-repellent properties, non-flammability and lightness, which has a three-layer structure due to the application on both sides (external and internal) of the base material by magnetron sputtering from a target with a purity of 99.99% of a thin film of silver, which has the highest among known metals, the reflectivity of infrared radiation is up to 0.99, which provides effective camouflage from thermal imaging detection devices. It is recommended to use Oxford fabric with a density of 200 to 600 denier as a base material for the manufacture of infrared radiation shielding material.

Flaps for reflecting infrared radiation in various directions and belt loops for attaching additional camouflage objects, sewn across the entire surface of the suit, are also made of material that screens infrared radiation, having a three-layer structure, and on the outer side of the material of the flaps and belt loops using water-based acrylic paint A camouflage pattern can be applied either by printing during the production of the material itself, or using a spray bottle, brush or spray on the finished suit directly on the ground. The flaps can be rectangular or triangular in shape.

A vertical slit can be made in the front part of the cape, for fixation (fastening) of which a Velcro strip is sewn along the cut line.

A camouflage suit is worn over clothing (uniform), avoiding direct contact with human skin. The best camouflage result is achieved when there is a small air gap between the suit and the surface of the body.

The described camouflage suit has a base in the form of a loose cape 1, which is made of infrared-shielding material. As an infrared radiation shielding material, a material is used that masks from thermal imaging surveillance devices, having a three-layer structure consisting of a base material, as well as outer and inner layers of a thin film of silver deposited by magnetron sputtering of a silver target with a purity of 99.99%. It is recommended to use Oxford fabric with a density of 200 to 600 den as the base material for the manufacture of infrared radiation shielding material.

In fig. Figure 1 shows a schematic illustration of the basis of a camouflage suit that camouflages in the infrared range. The basis of a camouflage suit is a loose cape 1 with loose sleeves 2, at the ends of which mittens 3 are sewn, and with a hood 4, equipped with a button 5 fastener at the front of the collar to cover a person’s neck. To ensure long-lasting camouflage in the infrared range due to the ventilation of the internal volume of the camouflage suit when worn in a raincoat e-cape 1, a zipper 6 is provided on the side.

The sleeves 2 at the ends and the hood 4 along the open edge are equipped with drawstrings 7 with tightening cords 8 for fixing the sleeve 2 along the arm and the hood 4 on the head, as well as for adjusting the open surface of the face.

In fig. Figure 2 schematically shows the base of a camouflage suit that camouflages in the infrared range, where a vertical cut 9 is made in the front part of the cape 1. Along the cut line 9, Velcro tape 10 is sewn on opposite sides of the suit base, as shown in FIG. 2, necessary for fixing (fastening) the incision 9.

Flaps 11 and belt loops 12 made of material that screens infrared radiation are sewn onto the entire surface of the suit base, the relative position of which is illustrated in Fig. 3. The flaps 11 are sewn with an overlap 13. The shape of the flaps 11 can be rectangular, as shown in Fig. 3, or triangular. The flaps 11 are sewn in such a way that the base of the costume is hidden under them. In the area of the shoulders of the cape 1 and the hood 4, the flaps 11 are sewn with an overlap 13, doubled, since in this area the contact of the suit with the person is greater. On mittens 3, flaps 11 are sewn only on the back side. Belt loops 12 for attaching additional masking objects are sewn at the base of the flaps 11, as shown in FIG. 3. The frequency of sewing belt loops 12 is 1 belt loop per 1 flap and, if necessary, can be increased or decreased.

In fig. 4 is a schematic representation of an infrared radiation shielding material used for making flaps 11 and belt loops 12 sewn onto a suit base. As shown in FIG. 4, on the outer layer 14 of the Material camouflaging from thermal imaging surveillance devices, consisting of a base material 15, an outer layer 14 and an inner layer 16 of a thin silver film, a camouflage pattern 17 is applied using water-based acrylic paint. Applying the camouflage pattern 17 to the outer layer 14 of the infrared shielding material can be done by applying water-based acrylic paint either by printing during the production of the material itself, or by using a spray bottle, brush or spray on the finished suit directly on site.

The weight of the suit is no more than 3 kg, depending on the base material used 15 and the size of the flaps 11 and overlap 13.

The possibility of obtaining a technical result is confirmed by testing.

In fig. Figure 5 shows images obtained from a thermal imaging device during testing of the effectiveness of the described camouflage suit, which camouflages in the infrared range. In fig. Figure 5 shows a person in the described camouflage suit 18 and a person in ordinary clothes 19. Tests were carried out using an iRey FH35R thermal imager under test conditions: night time, in a forest area, ambient temperature - 10 ° C, distance from the iRey FH35R thermal imager to objects 100 m, the wearing time of a camouflage suit is 1 hour. The tested camouflage suit was made of infrared radiation shielding material, the base material of which was Oxford fabric, 210 denier, 100% polyester, coated on both sides with surface density silver 0.4 g/ ^m2 . Over the entire surface of the base of the camouflage suit, rectangular shaped patches 11 of the same material are sewn in an overlapping manner. The dimensions of the flaps 11 are 12 cm in length and 11 cm in width, the overlap 13 is 4 cm horizontally and vertically, in the area of the shoulders and hood 4 the overlap 13 is twice as large. Belt loops 12 for attaching additional masking objects, 4 cm long, are sewn at the base of the flaps with a frequency of 1 belt loop per 2 flaps. Camouflage pattern 17 is applied to the outer side of the flaps 11 and belt loops 12 using a spray with water-based acrylic paints. The weight of the suit is 1.6 kg.

The test results showed high efficiency of camouflage in the infrared range with simultaneous camouflage of the surrounding area for a long time; the material works in rain and pollution.
