[0040] An anti-drone cartridge for smoothbore weapons (as illustrated in Fig. 1-15) comprises a case 1, a primer cap 2 that is mounted in a closed bottom part 3 of the case 1, a propellant charge 4, an obturator 5, a shock absorber 6 and a cylindrical container for a warhead, the container has an upper part that is closed with a cover gasket 8. A lower part of the cylindrical container may be provided with a removable bottom 7, or it is closed with a closing means, e.g., a plastic plug (not shown in the Figures). The cylindrical container for the warhead is assembled of at least two cassettes 9 that are successively arranged along an axis of the case.

[0041] A housing of the cassette 9 has a side wall 10 and exposed lower part 11 and an upper part 12 that are provided with a closing means. The cassettes 9 are interconnected by means of a lock connection. The removable botom 7 is provided with at least one fixing lock. This fixing lock may represent, e.g., a slit 13 in which a tongue 14 is inserted, and the slit is provided on a front side of the lower part of the cassette 9 (as illustrated in Fig. 5-7).

[0042] In order to structurally interconnect the cassetes 9, the tongue 14 that is provided on the front side of the lower part of the cassette and a groove 15 that is provided on a front side of the upper part of the cassette are used (as illustrated in Fig. 5, 6, 9, 10). Besides, the tongue 14 may be provided on the front side of the upper part of the cassete, and the groove 15 may be provided on the front side of the lower part of the cassete (not shown in the Figures).

[0043] In another embodiment of the utility model, in order to interconnect the cassetes 9, the tongue 14 that is provided on the front side of the lower part of the cassete and a slit 16 that is provided on a front side of the upper part of the cassete are used (as illustrated in Fig. 3-4). Besides, the tongue 14 may be provided on the front side of the upper part of the cassete, and the slit 16 may be provided on the front side of the lower part of the cassette (not shown in the Figures). The cassetes illustrated in Fig. 3-4 may be used for arranging pellets or semi-canister shot by pouring therein.

[0044] An external surface of a side wall of the cassette may be made smooth for quick opening of the cylindrical container (as illustrated in Fig. 3, 5, 9), or it may have ballistic grooves 17 (as illustrated in Fig. 4, 6, 10, 12, 13) for delivering the warhead to a maximum distance. It has been experimentally tested that the best embodiment is to make the ballistic grooves at an angle of between 2° and 75° relative to the axis of the case 1.

[0045] The cassettes with the ballistic grooves utilize a principle of a rifled barrel from the opposite, where the housing of the container instead of a rifle barrel is used for detwisting the warhead due to ballistic grooves. Furrows of the grooves are designed so as to allow the container to be rotated in the barrel without hindrance. And this approach enables shooting farther and more accurately using any smoothbore shotgun, which is especially appropriate when using grape canister shot. After the shot is made, the container assembled on the ballistic cassettes is twisted in the barrel, has high accuracy, and the warhead continues to rotate after destruction of the cassette that is especially important when using the grape canister shot or bullet. Due to identical weight and length of a rope of each grape canister shot, during detwisting, the charge is uniformly open under action of circumferential force, thereby destroying the cassette, and continues movement towards the target, while maintaining rotation, following a given route, thereby allowing, even low experienced shooters, to hit the targets which fly at a low altitude with high quality and with very high probability.

[0046] In one of embodiments, an internal side of the side wall of the cassette is provided with at least two guides that extend from the lower part to the upper part (as illustrated in Fig. 13). This designed of the side wall of the cassette allows to strengthen the cassette and the overall structure of the container in case of overload during the shot.

[0047] The warhead is put into each cassette 9 separately. The warhead may comprise: bullets, pellets, balls of semi-canister shot, balls of grape canister shot or a combined ammunition (bullet, pellets, canister shot, etc., simultaneously as illustrated in Fig. 14, 15).

[0048] In the anti-drone cartridge to be supplied with the canister shot or grape canister shot, the side wall of the housing of the cassette is made with at least two circular holes 18 for sealed arrangement of canister shot balls 20 in a horizontal row. Diameter of the holes is selected such that the canister shot balls 20 are fixed in said holes and compactly arranged horizontally from the top in the housing of the cassette 9.

[0049] As mentioned above, the warhead is put into each cassette 9 separately, and in order to separate the content of one cassette from another one, i.e., to close the space of the exposed lower and upper parts of the housing of the cassette, said exposed parts of the housing are closed with a gasket that is made of a paper sticker having a density of between 50 and 500 g / m2or of a self-adhesive film having a thickness of between 0.20 and 500 pm, or it is closed with a plastic plug having a thickness of between 0.2 and 0.4 mm.

[0050] The housing 1 of the cassette is made of plastic having a density of between 0.9 and 1.9 g / cm3. And the cylindrical container may utilize cassettes having the housing that is made of plastics with various density. Owing to the plastics which are different in terms of properties of frangibility, it is possible to control the destruction process of each cassette individually, if needed. For example, the first cassette is pulled, the second one is destroyed, the third one is ultra-rigid and reaches the target in undamaged state. The cassettes may be printed on a 3D printer or using industrial equipment using known technologies in this field of the art, thereby reducing their manufacturing costs.

[0051] Diameter of the housing of the cassette varies for various calibers of weapons and is between 9.0 mm and 26.5 mm.

[0052] Height of the housing of the cassette is between 5 mm and 40 mm. For example, for equipping the “Rhodesian cartridge” having a height of 40 mm, one or two cassettes are used; for the cartridge having a height of 70 mm, three cassettes are used; for the “Super Magnum” cassette having a height of 87 mm, four or more cassettes are used.

[0053] The utility model shall be explained with examples.

[0054] Example 1.

[0055] Fig. 5-6 illustrate cassettes for two canister shot balls.

[0056] The side wall of the cassette is provided with two circular holes 18 that are designed for compact arrangement of the canister shot balls 20 in a horizontal row. The cassette has two tongues 14 for connecting to another cassette or the bottom 7 (that is illustrated in Fig. 7) and two grooves 15, wherein the tongue 14 and the groove 15 represent a lock connection for assembling the cassettes.

[0057] Fig. 6 illustrates a cassette having the ballistic grooves 17 that are designed such that when several cassettes are assembled in the container, the furrows of the grooves 17 may extend as a continuous line through the entire plane of the container, thereby allowing to twist the container in the barrel without hindrance.

[0058] The cassettes are assembled in the container from two and more cassettes, fixed to each other by means of the lock connection, and the obtained structure is locked by the bottom 7 with the fixing lock. Alternatively, it is possible to use even one cassette with the bottom 7 for equipping the ultra-low, e.g. “rhodesian” cartridge, having the height of up to 40 mm in the anti-drone cartridge.

[0059] The cassette is not versatile for any diameter of the canister shot, thus, there are specific dimensions of the cassette for each caliber or diameter of the canister shot, and diameter of the holes and their height for the caliber.

[0060] The above-described cassettes may be equipped with grape canister shot (as illustrated in Fig. 8). To this end, a hole that must have a diameter of up to 1 mm is drilled in the canister shot balls 20. A rope 21 made of kevlar or rigid capron is cut into separate parts for length of between 30 and 120 cm. The canister shot balls 20 are secured to both ends of the rope 21, thereby obtaining a finished element ready to be stacked. Then, the ropes with the balls are stacked in the cassette such that their external surfaces touch the holes 18, and the ropes are located at the bottom. The ropes are stacked in the cassette 9 as a “wave” according to parachute line principle, and the lower part of the cassette is closed by means of a closing means 22, i.e., the circular paper gasket. Owing to this stacking, the rope 21 will not be fouled during destruction of the cassette, and opening of the warhead will be uniform. In this form, the cassette is ready to be stacked in the container.

[0061] Example 2.

[0062] Fig. 9-10 illustrate cassettes for three canister shot balls.

[0063] The side wall of the cassette is provided with three circular holes 18 that are designed for compact arrangement of the canister shot balls 20 in a horizontal row. The cassette has three tongues 14 for connecting to another cassette or the bottom 7 (that is illustrated in Fig. 11) and two grooves 15, wherein the tongue 14 and the groove 15 represent a lock connection for assembling the cassettes. Fig. 10 illustrates a cassette having the ballistic grooves 17 that are designed such that when several cassettes are assembled in the container, the furrows of the grooves 17 may extend as a continuous line through the entire plane of the container, thereby allowing to twist the container in the barrel without hindrance.

[0064] The cassettes are assembled in the container from two and more cassettes, fixed to each other by means of the lock connection, and the obtained structure is locked by the bottom 7 and the fixing lock. Alternatively, it is possible to use one cassette with the bottom 7 for equipping the ultra-low, e.g. “Rhodesian” cartridge, having the height of up to 40 mm in the anti-drone cartridge.

[0065] The cassette is not versatile for any diameter of the canister shot, thus, there are specific dimensions of the cassette for each caliber or diameter of the canister shot, and diameter of the holes and their height for the caliber.

[0066] The above-described cassettes may be equipped with grape canister shot (as illustrated in Fig. 8). To this end, a hole that must have a diameter of up to 1 mm is drilled in the canister shot balls 20. A rope 21 made of kevlar or rigid capron is cut into three identical parts having a length of between 10 and 120 cm. The canister shot ball is secured to each part of the rope, thereby forming a separate element being a so-called “beam”. Then, three “beams” are linked from another end of the rope to form a central node, thereby creating a kind of tying of ropes and beams that have identical length and with the canister shot ball secured to their ends.

[0067] Then, the ropes with the balls are stacked in the cassette such that their external surfaces touch the holes 18, and the ropes are located at the bottom. The ropes are stacked in the cassette 9 as a “wave” according to parachute line principle, and the lower part of the cassette is closed by means of a closing means 22, i.e., the circular paper gasket. Owing to this stacking, the rope 21 will not be fouled during destruction of the cassette, and opening of the warhead will be uniform. In this form, the cassette is ready to be stacked in the container.

[0068] Example 3.

[0069] Fig. 12 illustrates the cassette 9 into which a bullet is stacked. The cassette has a cylindrical shape with solid walls for arranging the bullet in the middle. The cassette is made with three tongues 14 for connecting to another cassette or to the bottom 7. These cassettes are assembled in the container of from two and more cassettes, or it is possible to use even one cassette with the bottom 7 for equipping the ultra-low, “rhodesian” cartridge having a height of up to 40 mm. If this cassette is used in the mixed assembly, it should be always on the top (above the canister shot, pellets, etc.). The cassette has ballistic grooves 17, their purpose and designed are described in Examples 1-2.

[0070] Specific dimensions of the cassette are selected for each caliber, and the dimensions vary in terms of diameter and height. The bullet inside the cassette is pressed or high-efficient adhesive or glue is used to rigidly hold the bullet in the container.

[0071] Example 4.

[0072] Fig. 14 illustrates that all three cassettes in the cartridge are equipped with a different warhead, namely, pellets 24, semi-canister shot balls 23 and canister shot balls 20. The cartridge comprises the case 1, the primer cap 2 that is mounted in the closed bottom part 3, the propellant charge 4, the obturator 5, the shock absorber 6 and the cylindrical container for the warhead, and the lower part of the container is made with the removable bottom 7, and the upper part of the container is closed by the cover gasket 8. The cylindrical container for the warhead is assembled of three cassettes 9 that are successively arranged along an axis of the case.

[0073] A shot with the anti-drone cartridge is performed as follows (as illustrated in Fig. 15):

[0074] - a point 25 pierces the cap 2;

[0075] - the cap 2 ignites the propellant charge 4;

[0076] - the propellant, upon initiation, creates an excessive pressure, thereby pushing the content of the cartridge out from the case 1;

[0077] - the obturator 5 avoids penetration of propellant gases inside the cartridge when making the shot; - the shock absorber 6 makes a boost of the warhead smoother;

[0078] - when making the shot, the equipped containers 9 are boosted inside the barrel 26 and gain maximum designed speed;

[0079] - outside the barrel 26 beak, the cartridge loses accompanying elements such as obturator, shock absorber, gaskets, thereby initiating a self-destruction process;

[0080] - the containers are completely destroyed at a distance of about 5-10 meters from the barrel beak and the warhead (canister shot, semi -canister shot, pellets in this example), in the course of opening, continue movement towards the target, while maintaining a maximum impulse and cover a wide coverage area;

[0081] - the warhead hits the target.

[0082] Advantages of the claimed cartridge include:

[0083] - a possibility of equipping the cassettes with various types of the warhead (pellets, canister shot, bullets, etc.);

[0084] - a possibility of using one and more cassettes, i.e., a possibility of creation of the cartridges of various heights;

[0085] - high-quality adjustment of the weight of the warhead (weighing) may be not more than 34 g (hi combat conditions, it allows to deliver accurate and adjusted fire very quickly);

[0086] - a possibility of high-quality stacking of the grape canister shot;

[0087] - wide coverage area;

[0088] - inexpensive manufacturing;
