Description

Technical Field

[0001] The invention relates to the technical field of armor-piercing bullets, in particular to an armor-piercing bullet without armor and preventing ricocheting. Background Art

[0002] The power of armor-piercing bullets generally depends on the armor-piercing steel core covered by armor and lead jackets. When the bullet interacts with the target, the armor and lead jacket often cannot penetrate the protective armor and cannot damage the high-value targets behind the protective armor. Traditional bullets are prone to ricocheting when hitting hard targets, which may cause unexpected injuries and threats. The development of unarmored armor-piercing projectiles is related to the threat to heavy armored targets on the modern battlefield. As the protection capabilities of tanks and other armored vehicles continue to improve, traditional armor-piercing technology faces challenges. Therefore, the design of unarmored armor-piercing projectiles aims to overcome these challenges and provide infantry and other platforms with more effective anti-armor capabilities.

[0003] Traditional armor-piercing bullets are generally composed of a jacket, a lead sleeve and an armor-piercing steel core. The jacket is generally composed of copper or copper-clad steel, which plays the role of covering the armor-piercing steel core. At the same time, it is used in combination with the lead sleeve to make the bullet rotate at high speed and seal the gunpowder gas during the firing process.

[0004] The design of the capped armor-piercing projectile can reduce ricocheting, and the design of the fin-stabilized discarding sabot projectile can improve armor-piercing ability and reduce resistance during flight. However, when an armor-piercing projectile hits an inclined armor, it may ricochet due to uneven force, that is, the projectile body is bounced off instead of penetrating the armor. Summary of the invention

[0005] The purpose of the present invention is to provide an armor-piercing bullet with no blunderbuss. Compared with the traditional armor-piercing bullet, the negative mass proportion of the projectile is reduced, the kinetic energy loss is reduced, and the armor-piercing penetration capability is improved by adjusting the core mass and the proportion of the armor. The armor-piercing bullet with no blunderbuss improves the pitting penetration capability, prolongs the residence time of the projectile on the target plate surface, improves the overturning torque received by the projectile, and effectively suppresses the projectile from blundering, and effectively improves the oblique penetration capability of the anti-armor bullet.

[0006] To achieve the above-mentioned purpose, the present invention provides an armor-piercing bullet with no armor and anti-bouncing, including a bullet body, the bullet body includes a bullet core, a resistance device is connected to the front end of the bullet core, a bullet belt assembly is arranged on the side wall of the bullet core, and a bottom recess is opened at the tail of the bullet core.

[0007] Preferably, the resistance device comprises a wind hood, and the wind hood is fixedly connected to the elastic core.

[0008] Preferably, the elastic belt assembly includes a front elastic belt and a rear elastic belt, a dovetail groove is provided on the elastic core, the rear elastic belt is placed in the dovetail groove, a groove is provided in the upper middle part of the elastic core, and the front elastic belt is placed in the groove.

[0009] Preferably, the hood is made of aluminum alloy, the core is made of high-strength steel, the front elastic band is made of copper, and the rear elastic band is made of brass.

[0010] Preferably, the upper end of the hood is in the shape of a cone with a rounded tip, and the lower end is in the shape of a cylinder, the bottom diameter of the upper end is larger than the diameter of the lower end, and the lower end of the hood is inserted into the elastic core.

[0011] Therefore, the present invention adopts the above-mentioned non-armored anti-bounce armor-piercing bullet, which has the following beneficial effects: (1) Compared with traditional armor-piercing bullets, the negative mass ratio of the projectile is reduced by adjusting the core mass and the proportion of armor, thereby reducing kinetic energy loss and improving armor-piercing capability; (2) Compared with traditional armor-piercing bullets, unarmored armor-piercing bullets can effectively suppress projectile ricocheting and improve the oblique penetration capability of anti-armor bullets by controlling the shape of the head, improving the cratering penetration capability, prolonging the residence time of the projectile on the target surface, and improving the overturning torque exerted on the projectile.

[0015] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0017] Embodiment 1 like Figure 1 to Figure 2 As shown, the present invention provides an armor-piercing bullet without armor and anti-bounce, including a projectile body, which is used to penetrate a target. The projectile body includes a core 2, and the core 2 is made of high-strength steel. When the gas generated by the combustion of gunpowder pushes the core 2 in the shell to fly out of the barrel at high speed, the kinetic energy carried by the core 2 is transferred to the target, causing damage. The front end of the core 2 is connected to a resistance device, which is used to reduce air resistance. A belt assembly is provided on the side wall of the core 2, and the belt assembly is used to reduce the negative mass ratio of the projectile.

[0018] A bottom concave 5 is provided at the tail of the core 2, and the resistance device includes a hood 1. The upper end of the hood 1 is a conical shape with a rounded tip, and the lower end is a cylindrical shape. The bottom diameter of the upper end is larger than the lower end diameter. The lower end of the hood 1 is inserted into the core 2. The hood 1 is fixedly connected to the core 2. The hood 1 is made of aluminum alloy, which effectively reduces air resistance and improves the flight stability and shooting accuracy of the projectile. The combination of the bottom concave 5 and the hood 1 can move the center of mass of the projectile forward and the center of pressure backward, reduce the ratio of the equatorial moment of inertia to the polar moment of inertia of the bullet, and reduce the actual turning torque, which ultimately ensures the flight stability and shooting accuracy of the projectile.

[0019] The belt assembly includes a front belt 3 and a rear belt 4. The front belt 3 is made of copper, and the rear belt 4 is made of brass. The front belt 3 and the rear belt 4 can reduce the negative mass of the projectile by more than 80%. A dovetail groove is provided on the core 2, and the rear belt 4 is placed in the dovetail groove. A groove is provided in the middle and upper part of the core 2, and the front belt 3 is placed in the groove.

[0020] A design method for an armor-piercing bullet without a jacket and preventing it from bouncing is as follows: first, a circle of dovetail grooves is opened on a core 2 of the armor-piercing bullet, and a rear belt 4 is pressed into the core. The rear belt 4 plays the role of guiding rotation and holding air during the firing process, thereby ensuring the correctness of the movement of the core 2 in the bore; then, a groove is opened in the upper middle part of the core 2, and a front belt 3 is pressed into the core, and a tightening groove is processed to facilitate the connection between the core 2 and the cartridge, and to guide the core 2 to enter the bore, and to prevent the core 2 from nutating when entering the bore, thereby affecting the movement in the bore and the flight posture.

[0021] The preliminary experiments were conducted to improve the anti-bounce capability of the projectile by improving the crater penetration capability and the turning torque on the projectile. Part of the projectile head mass was sacrificed and the projectile posture was adjusted to allow it to penetrate the target plate smoothly and move in a direction that is favorable for penetration. In the case of high-speed and high-angle impact, the resistance of the projectile to the target plate is seriously asymmetric, and the projectile-target action time is very short. If the projectile cannot complete the crater penetration and intrusion into the target plate in a sufficiently short time, it is very likely to bounce off. After the ordinary projectile intrudes into the target plate at a high angle, the target plate material is squeezed by the continuously intruding projectile and moves at high speed toward the free surface in front of the projectile on both sides, expanding and expanding the hole, and breaking and shattering occur at the same time. The broken target plate fragments are thrown out along the axis of the projectile.

[0022] The resistance of the target plate to the projectile reduces the speed of the projectile and causes it to break. The fragments produced by the broken head of the projectile are thrown out together with the target plate fragments. In this process, the lower surface of the projectile head is always in direct contact with the target plate, while the upper surface is in contact with the target plate through fragments. In the lateral direction, due to the difference in the media on both sides of the projectile head, the projectile is subjected to a lateral resistance given by a target plate. This lateral resistance increases the turning torque of the projectile, making it easier for the projectile to bounce. Therefore, controlling the head breakage, reducing or turning the turning torque on the projectile to a favorable direction, and suppressing the projectile from bouncing is a key scientific issue in preventing anti-bounce projectiles from bouncing again after intrusion. By controlling the shape of the head, improving the ability to penetrate into the pit, prolonging the residence time of the projectile on the target plate surface, and improving the turning torque on the projectile, the projectile can be suppressed from bouncing and the oblique penetration ability of anti-armor bullets can be effectively improved.

[0023] Therefore, the present invention adopts the above-mentioned non-jacketed anti-bounce armor-piercing bullet. Compared with traditional armor-piercing bullets, the negative mass ratio of the projectile is reduced by adjusting the core mass and the proportion of the jacket, thereby reducing the kinetic energy loss and improving the armor-piercing penetration capability; the non-jacketed armor-piercing bullet effectively suppresses the projectile from bouncing and effectively improves the oblique penetration capability of the anti-armor bullet by controlling the head shape, improving the pitting penetration capability, prolonging the residence time of the projectile on the target plate surface, and improving the overturning torque exerted on the projectile.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
