Description

GUN CARTRIDGE WITH A CAPE

[0001] The invention relates to weapons, specifically to means for increasing the area of ​​mechanical damage to small objects with a barreled weapon using a cape. The invention is applicable for hunting, countering flying drones, ensuring the security of stationary objects, vehicles, and public events in open areas.

[0002] The prototype of the claimed technical solution is a weapon cartridge with a cap, described in US Patent 5,315,932 A, dated May 31, 1994. It contains a cap consisting of threads fastened at their first ends. Weights are attached to the second ends of the threads.

[0003] A drawback of the well-known capped weapon cartridge is that the cape it fires constantly changes its lethal area as it flies toward the target. The weight at the end of each thread, receiving a random lateral impulse after firing, flies sideways until the thread connecting it to the other weights becomes taut. At this point, the thread's lethality is at its maximum. After it is fully taut, the return impulse from the other threads with the other weights attached to them immediately causes the weight to begin moving in the opposite direction. The thread's lethality decreases as a result. The oscillating motion of the weights as they fly toward the target and the periodic decrease and increase in the cape's lethal area are clearly demonstrated in slow-motion footage taken during testing. A video demonstrating the testing is available online at https: / / vk.com / video-32447065_456239222.The transverse oscillatory movements of the weights are shown at the 10-minute mark of the video, as well as in subsequent sections. Due to the changing lethal area of ​​the known cape, there is a technical problem—a low probability of hitting the target.

[0004] The purpose of this technical solution is to increase shooting efficiency.

[0005] To solve a technical problem and achieve a technical result, the design of a known device was modified. A known cartridge has a capped cartridge, comprising a cartridge case, a primer cap at the rear of the case, a propellant charge in front of the primer cap, and a cap in front of the propellant charge. The cap consists of threads and weights. The threads are fastened at their first ends and arranged so that they straighten when stretched by their second ends. The weights are attached to the second ends of the threads. In addition to the known technical solution, the threads of the cap are glued together near the fastening point between the first and second ends.

[0006] Each weight at the end of each thread of the cape receives a lateral momentum component of arbitrary magnitude when fired from a rifle cartridge. The weight moves not only forward but also sideways until the threads connecting it to the other weights become taut. After this, the thread begins to separate from the section of bonded threads. As a result of this separation, the weight's velocity gradually decreases to zero. Oscillatory movements of the weights during their flight toward the target and the periodic decrease and increase of the cape's striking area are absent or insignificant. Thanks to the proposed modifications to the cape, the goal is achieved with the technical result.

[0007] Furthermore, in the area of ​​bonded threads, they can be parallel, and in the cross-section of the area of ​​bonded threads, the cross-sections of the threads are arranged sequentially. In this case, the area of ​​bonded threads forms a ribbon-like shape.

[0008] In addition, on the part of the area of ​​glued threads adjacent to the place of fastening, the area of ​​glued threads can be additionally covered with a layer of glue.

[0009] In addition, on the part of the glued threads adjacent to the bonding point, the glue may be stronger than on the rest of the area.

[0010] In addition, in the part of the area of ​​glued threads adjacent to the place of fastening, the adhesion of the glue to the threads may be stronger than in the rest of the area.

[0011] Furthermore, the section of bonded threads may further comprise an extended elastic element located along the section and connected to it along its entire length. The extended elastic element may be made of an elastic strip. In this case, the elastic strip, in its cross-section perpendicular to the bonded threads, may be shaped like an arc of a circle. The central angle of the arc in this case does not exceed 180 degrees.

[0012] In addition, the threads can be made of aromatic polyamide material.

[0013] In addition, the adhesive can be polymerized polyurethane.

[0014] The technical result that this technical solution is aimed at achieving is to increase the probability of destruction by ensuring the constancy of the damaging area. Figure 1

[0026] Schematically depicts the cape immediately before hitting the target. Some threads are taut, partially pulled out from the area of ​​​​the glued threads.

[0027] A capped weapon cartridge comprises a cartridge case 1 having an imaginary longitudinal axis 2, a primer 3 in the rear portion of the cartridge case 1, a propellant charge 4 in front of the primer 3, and a wad 5 in front of the propellant charge 4. Threads 6 of cap 7 are compactly arranged in front of wad 5. Threads 6 are arranged so as to be able to straighten when stretched by their second ends. A section of glued threads 8 of cap 7 is also located in front of wad 5. The section of glued threads 8 is twisted into a spiral. The axis of the spiral is parallel to the imaginary longitudinal axis 2 of the sleeve 1. Weights 9 and 10 are located in the front part of the sleeve 1. The second ends of the threads 6 are secured in weights 9 and 10. The sleeve is hermetically sealed at the front by a plug 11.

[0028] The section of glued threads 8, twisted into a spiral, is shown in the cross-section of the cartridge. Knot 15 fastens the first ends of threads 6. The cross-section of the cartridge along weights 9, 10, 16, 17, 18, and 19 is shown in.

[0029] The cape 7, shown in the straightened state on , contains threads 6, fastened by their first ends. The fastening of threads 6 is knot 15. Between the first and second ends in the area near the fastening place of thread 6 of the cape 7 are glued together to form a section of glued threads 8. Weights 9, 10, 16, 17, 18 and 19 are fastened to the second ends of threads 6. Between the first and second ends in the area near the fastening place of thread 6 of the cape are glued together with glue 20 (), forming a section of glued threads 8 (and 5). In the section of glued threads 8, threads 6 are parallel (). In the cross-section of the section of glued threads 8, the cross-sections of threads 6 are arranged sequentially, to form a ribbon-like shape of the section of glued threads 8.

[0030] A longitudinal section of the chuck, in which the section of glued threads 8 is arranged in a zigzag pattern, is shown in [Figure 1]. Unit 15 is located in the plane of the section. The rest of the designation and arrangement of components in the chuck are similar to those shown in [Figure 1].

[0031] The central portion of a more complex cape is shown in [fig. 1]. The second ends of threads 6 with weights are not shown. The section of bonded threads 8 contains an extended elastic element of rectangular cross-section, made of a thin strip of 25 hardened steel. Threads 6 are made of aromatic polyamide.

[0032] A cross-section of a section of bonded threads 8, taken remotely from the thread bonding point—node 15—is shown in . The cross-sections of threads 6 are bonded with adhesive 20. Adhesive 20 is polymerized polyurethane. Strip 25 is shaped in cross-section as a circular arc, with a central angle 23 of 60 degrees.

[0033] A cross-section of the section of bonded threads 8, but taken near knot 15, is shown in . The adhesive 26 on this portion of section 8 is stronger than on the rest of it. Section 8 is additionally coated on the outside with a layer of adhesive 26. Threads 6 are more fuzzed on this portion of the section of bonded threads 8, so the adhesion of adhesive 26 to them is stronger than on the rest of section 8.

[0034] For more reliable operation of the cartridge with the cap, it can be placed in a wad-container 27 () inside the cartridge. In this case, the section of bonded threads 8 with a thin steel strip 25 is twisted into a spiral so that the axis of the spiral is parallel to the longitudinal axis 2 of the cartridge case 1. When twisted, the strip 25 straightens in its cross-section, and its arcuate shape disappears. The ability of the strip 25 to straighten the section of bonded threads 8 after exiting the barrel significantly reduces the likelihood of tangling the threads near the knot 15 as the cap approaches the target.

[0035] The device operates as follows. The cape, shown in the position laid in the cartridge case (#6 or #10), is fired toward target (#28). After the shot, the cape begins to move forward. Its weights interact with the cartridge case (#10, #6 or #10), the plug (#11), the barrel (#29) of the weapon (#45), the wad (#45), and the container (#27), experiencing air pressure on their faces as they fly toward the target (#28). As a result of this interaction, in addition to the longitudinal component of the shot's impulse, they receive a transverse (lateral) component. The magnitude of the lateral component of the impulse is small compared to the longitudinal component, but is random, since it depends on many independently acting random factors.

[0036] The cape weights depicted in [Figure] received different lateral impulse components. Shortly after their exit from the weapon's barrel 29, weights 9, 10, 16, and 18, having received greater lateral impulse, traveled a greater distance from the section of bonded threads 8 than weights 17 and 19.

[0037] When threads 1, connecting weights 9, 10, 16, and 18 to the section of glued threads 8, are stretched, the threads begin to separate from it, breaking the adhesive 20 (and 8). Threads 6 also begin to peel away from adhesive 20. Further movement of the weights is accompanied by braking forces exerted by threads 6. The glued threads form a shock absorber, converting the kinetic energy of the transverse movement of each weight into work to break the adhesive layer and / or to separate the threads from the adhesive. The speed of weights 9, 16, and 18 () decreases to zero.

[0038] However, load 10, due to the large values ​​of all random factors influencing the lateral component of its momentum, acquired a very high lateral velocity as a result of the shot. The area of ​​destruction of adhesive 20 (), which its thread 6 () reaches as a result of separation from the section of glued threads 8, reaches the stronger adhesive 26 () at the rear of section 8, which also has a greater thickness and stronger adhesion to adhesive 26. As a result of the significantly increased braking force, the velocity of load 10 also decreases to zero.

[0039] There is no subsequent movement of the weights back toward the center of the cape. The destructive properties of the threads remain constant. Oscillatory movements of the weights during their flight toward the target and the periodic decrease and increase in the cape's destructive area are either absent or insignificant.

[0040] The claimed device can be used on a permanent basis for loading ammunition for hunting, countering flying drones, ensuring the security of stationary facilities (including airports and stadiums), vehicles, and public events in open areas. The cape can also be temporarily deployed in combat situations during military operations. The cape is most successfully used to destroy drones with flight programs capable of completing their final trajectory without operator radio control or the use of radio navigation systems.

[0041] The invention has been disclosed above with reference to specific embodiments. Other embodiments of the invention may be apparent to those skilled in the art without altering its essence as disclosed herein. Accordingly, the invention should be considered limited in scope only by the following claims.

[0042] No
