Technical Field

[0001] The invention belongs to the technical field of armor-piercing warheads, and in particular relates to a combined energetic charge cap and a charge structure. Background Art

[0002] The armor-piercing warhead is mainly composed of a liner, a pressure ring, a partition, a charge and a shell. The armor-piercing warhead relies on the high-speed jet formed by the charge explosion to crush the liner and penetrate the target, while producing a small amount of aftereffect fragments to damage the instruments and equipment inside the target. The liner is the main damage unit of the armor-piercing warhead to damage the target, and its structure, material composition and dynamic mechanical properties have an important influence on the power of the armor-piercing warhead.

[0003] Traditional charge liner materials mainly include red copper, tantalum-tungsten alloy, tungsten-copper alloy, etc. The materials have the characteristics of high density and high ductility. The high-speed and high-density jets formed can form deep penetration holes in the target. However, due to the characteristics of the material itself, the penetration holes are small, so the damage effect after penetrating the target is poor.

[0004] How to enhance the striking power of traditional charge liners and effectively improve the damage effect of armor-piercing warheads while retaining high penetration performance is an important direction of current research and development. Summary of the invention

[0005] The present invention provides a combined energetic charge liner and a charge structure. The combined energetic charge liner combines the advantages of the energetic charge liner and the traditional inert charge liner by installing an energetic box body on the top of the charge liner, meets the dual damage requirements of high penetration and large aftereffect of the armor-piercing warhead, and can effectively improve the damage aftereffect of the armor-piercing warhead while retaining the high penetration performance.

[0006] In order to achieve the above object, the present invention adopts the following specific technical solutions: The present invention provides a combined energetic charge liner, which is composed of an inert charge liner and an energetic box body; The top of the inert drug-shaped liner is provided with a circular opening; The energetic box body is a cylindrical structure made of energetic material; the energetic box body is located outside the top of the inert drug-type liner, and one end of the energetic box body is connected to the circular opening.

[0007] Furthermore, the inert liner is a conical structure, and the energetic box is coaxially arranged with the inert liner.

[0008] Furthermore, the inert liner is made of a high-density, high-ductility inert material.

[0009] Furthermore, the energetic material is an energetic material with high energy density, low elongation and easy breakability.

[0010] Furthermore, the energetic material is a high entropy alloy.

[0011] Furthermore, the diameter of the energy-containing box body is equal to the diameter of the circular opening.

[0012] In addition, the present invention also provides a charge structure, which includes a shell, a charge column and the above-mentioned combined energetic charge liner; The drug column and the combined energetic drug liner are both installed in the shell; The drug column is provided with a groove at the center of one side connected with the combined energetic drug liner; The energetic box body of the combined energetic medicine cover is installed in the groove in a shape-matched manner.

[0013] Furthermore, the drug column includes a secondary drug column, a main drug column and a partition; The auxiliary charge column is installed at the bottom end of the shell; The partition is placed between the auxiliary drug column and the main drug column; The main charge column is clamped between the auxiliary charge column and the combined energetic charge liner, and the groove is provided at the center of one end facing the combined energetic charge liner.

[0014] Furthermore, it also includes a pressure ring; The pressure ring is fixedly connected to the shell and is used to compress the outer end of the liner of the combined energetic liner.

[0015] Furthermore, the shell, the secondary charge, the main charge, the partition, the charge liner, the energetic box body and the pressure ring are all axially symmetrical structures and are coaxially arranged.

[0016] Compared with the prior art, the technical solution of the present invention has the following beneficial effects: The combined energetic charge liner of the present invention is composed of an inert charge liner and an energetic box body, and the cone top of the inert charge liner is removed, and a circular opening is opened at the top of the inert charge liner. The inert charge liner is made of an inert material with high density and high ductility.

The energetic box body is made of an energetic material with high energy density, low elongation and easy-to-break properties. After the explosive is detonated, the energetic box body mainly forms a pestle, which follows the jet and enters the target to release energy. After passing through the deep hole constraint on the target plate, it diffuses and breaks into a large number of small fragments after the target, and releases chemical energy, effectively improving the aftereffects such as hole expansion, ignition and overpressure of the armor-piercing warhead after the target, and has a significant damage effect on the internal equipment and manpower of the confined space. Therefore, the above-mentioned combined energetic charge liner can improve the penetration power and aftereffect power of the armor-piercing warhead under the same mass and charge caliber.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1 This embodiment provides a combined energetic charge liner, such as Figure 1 As shown, the combined energetic charge liner consists of an inert charge liner 6 and an energetic box body 5; the inert charge liner 6 is made of a high-density, high-ductility inert material; a circular opening is provided at the top of the inert charge liner 6; the inert charge liner 6 is a conical structure, and the energetic box body 5 and the inert charge liner 6 are coaxially arranged.

[0021] The energetic box body 5 is a cylindrical structure made of energetic material, which has high energy density, low elongation and easy-to-break properties, and can be a high-entropy alloy; the energetic box body 5 is located outside the top of the inert liner 6, and one end is connected to the circular opening. The diameter of the energetic box body 5 is equal to the diameter of the circular opening.

[0022] Embodiment 2 This embodiment provides a charge structure for an armor-piercing warhead, and the charge structure is an axisymmetric structure, such as Figure 1 As shown in the structure, it includes a shell 1, an auxiliary charge 2, a main charge 3, a partition 4, a pressure ring 7 and the combined energetic charge cap in the above-mentioned embodiment; the combined energetic charge cap is composed of an energetic box body 5 and an inert charge cap 6; the auxiliary charge 2, the main charge 3, the partition 4, the combined energetic charge cap and the pressure ring 7 are all installed in the shell 1; the shell 1 is composed of a coaxial conical part and a circular ring part, and the conical part and the circular ring part can be an integral structure, the small end of the conical part is the bottom end of the shell 1, the large end of the conical part is connected to one end of the circular ring part, and the other end of the circular ring part is an opening; the auxiliary charge 2 is installed at the bottom of the shell 1, the partition 4 is placed between the auxiliary charge 2 and the main charge 3, and the end faces of the auxiliary charge 2 and the main charge 3 that contact each other are provided with pits that match the shape of the partition 4, as shown in FIG. Figure 1 In the embodiment, the partition 4 is composed of a cone embedded in the pit of the auxiliary medicine column 2 and a spherical cap embedded in the pit of the main medicine column 3; Figure 1 As shown, the large end of the main drug column 3, that is, the end of the main drug column 3 facing the inert drug cap 6, is also the end of the main drug column 3 away from the auxiliary drug column 2. A groove for installing the energetic box body 5 is arranged at the center of the large end of the main drug column 3. The energetic box body 5 is installed in the groove of the main drug column 3. The other end of the energetic box body 5 is pressed by the inert drug cap 6. All parts are pressed and fixed by the pressing ring 7, so that the auxiliary drug column 2, the main drug column 3, the partition 4 and the combined energetic drug cap are fixedly installed in the shell 1. The shell 1, the auxiliary drug column 2, the main drug column 3, the partition 4, the drug cap, the energetic box body 5 and the pressing ring 7 are all axially symmetrical structures and are coaxially arranged.

[0023] The working process of the above-mentioned charge structure is as follows: After the charge is detonated, the inert charge liner 6 collapses and closes under the action of the detonation wave, and the energetic box 5 is deformed accordingly. Due to the different collapse speeds, time constants and collapse angles, the cover materials at different positions on the inert charge liner 6 will form jets or pestles; Figure 2 As shown, the serial numbers of different positions on the inert drug liner 6 a , b , c , d , eIt is used to mark the positions of the corresponding jets and pestles. It can be seen from the figure that the arrangement order of the jets is consistent with the serial numbers, and the arrangement order of the pestles is opposite to the serial numbers. Therefore, from the direction of the generatrix of the inert liner 6, the conical liner close to the top of the inert liner 6 has a certain mass proportion that can form a high-speed jet, and most of the liner material at the large end of the inert liner 6 and the outside of the liner top will form a pestle with a lower speed.

[0024] According to the mass distribution ratio of the jet and the pestle after the liner is formed, the liner is set as a combined energetic liner structure, the cone top of the conical liner is removed, and a high-density, high-ductility inert material is used. After the explosive is detonated, a jet is mainly formed, which penetrates the target plate to form a deep hole; an energetic box body 5 is installed on the top of the liner. The material has high energy density, low elongation and easy-to-break properties. After the explosive is detonated, this part of the material mainly forms a pestle, which follows the jet and enters the target to release energy. After passing through the deep hole constraint on the target plate, it diffuses backward behind the target and breaks into a large number of small fragments, and releases chemical energy, such as Figure 3 As shown, the aftereffects of the armor-piercing warhead, such as hole expansion, ignition and overpressure, are effectively enhanced, and the destructive effect on the equipment and manpower inside the confined space is obvious.

[0025] The combined energetic charge liner of the present invention can improve the penetration power and aftereffect power of the armor-piercing warhead under the same mass and charge caliber. The above-mentioned combined energetic charge liner has a reasonable design, outstanding effect, and has a large space for promotion and application.
