Description

[Detailed description of the invention] projectile The present invention relates to projectiles, and more particularly to armor-piercing projectiles having a motherboard core therein. do.

Brief description of prior art Two types of armor-piercing projectiles have been used to date. The initial design was The lightweight material in the nose section and the sintered material behind the external section that forms the rest of the projectile. A full caliber type with a normal projectile shape consisting of a core of filled steel or dense material there were.

This type of projectile had limited armor plate capability. More recently, high-density materials A Rondo-type mother aircraft produced by this company appeared, and this is it.

The armor plate motherboard function is greater than the full-caliber design. The only way to do this is to take advantage of O-Rad's high trajectory flight ability. during handling, storage, and firing to increase the initial rate of fire. The bullet bottom plate was designed so that it would wrap around the mother fuselage and be abandoned immediately after exiting the muzzle. This made it possible to continue the flight with only the rod mother aircraft facing the target. death However, if the process of abandoning the bottom plate is included, the trajectory of the rod projectile will not only become inaccurate. This also results in a loss of mass energy.

Designed to solve the above problems and contribute to the target motherboard process. An object of the present invention is to provide an armor-piercing projectile.

According to the invention, the armored plate protects the target so that it is suitable for firing from the gun barrel. The combination projectile has a forward facing open front end and an opposite ballistic motion towards the target plane. a rigid hollow carrier having a rear end in the direction, said front end having an annular shape; a carrier having a non-deformed leading edge and a sliding fit within said carrier; a motherboard core adapted to accommodate said motherboard at a forward end of said carrier; It is possible to slide out of the carrier, but not at the rear end of the carrier. the core is adapted to host an armored target and the projectile is fired. the front end located within the carrier and behind the leading edge of the carrier when and an invasive core having an end.

The projectile according to the invention surprisingly does not require the use of abandoned parts and is described below. A unique method in which both the carrier and the corrosive core contribute to the parent process. , improving mothership effectiveness against armored targets.

Preferably, the projectile is elongated, generally cylindrical, and has a sharp annular leading edge. destination At the head edge, slopes are provided on both the inner and outer surfaces of the carrier, and these slopes intersect. to form the leading edge.

The rear end of the carrier may be tapered to reduce aerodynamic drag. tree The rear end of the core may similarly be tapered to facilitate insertion into the carrier.

The restraining member forms an end of an inner hole into which the mother body fa is inserted with a snug fit. Can be wall or color. The rear end of the carrier itself is closed and acts as a restraining member. May form a working wall.

The motherboard core may be restrained in direct contact with a wall, or as described in more detail below. One or more intermediate members may be provided between the wall and the core to do so.

It is preferable to The taper may be provided as a single conical section or as an alternative. If you look at the cross section, you can see that multiple conical cross sections with different taper angles are overlapped to form the front surface of the core. It is also possible to have a cross section that gradually converges in the direction.

However, the forward end of the core preferably has a pointed annular undeformed leading edge. It's fine. The core may be cylindrical or partially cylindrical, with a core within the inner bore of the cylindrical portion. The inner hole may include another member slidably provided therein. parts like this It can also contribute to the target mother process. Therefore, this member is also located behind the front end of the core body. The target mother aircraft may have a forward edge provided on the carrier after launch. The process is carried out in three stages: the rear, the core body, and other parts that are slip-fitted into the core body. be called.

The shape of other members may be any shape that the core itself has as an integral structure. .

The forward end of the core is e.g. Placed at approximately the same position as or slightly behind the starting point of the slope forming the edge. It would be good if you could.

The core is at least partially made of, for example, a tungsten alloy or irradiated uranium. It is preferable to make it from a high-density material suitable for the motherboard of armor plates. These materials are Known to those skilled in the art.

The forward end of the core is made of said high-density material; A steel-like structure designed to make the initial mother plane of the target surface even larger, like Chichi. It may also include a tip made of a lighter weight material.

The projectile according to the invention may further include a lock at or adjacent to the forward end of the carrier. Preferably, it includes a nose fixed to the carrier. Such a hot water part has a conical or pointed shape. Preferably, it is a shaped body with an arch-like hollow structure, which is directed toward the target. Adapted to act as a shield to reduce the projectile's aerodynamic drag during flight. will be combined. Even made of lightweight materials such as plastic materials or aluminum alloys This good snout easily disintegrates upon impact with a target. For example, accompanying wax body etc. The material may be enclosed within a cavity within the nose.

The projectile carrier according to the invention may be manufactured in one piece, for example from high-strength steel. may alternatively include a plurality of dissimilar materials. For example, the beginning of the carrier The parts including the edges are made of high-strength, high-hardness materials, such as high-strength steel, while the rear The side portion may be made of lightweight materials such as aluminum alloy or fiber-reinforced composite materials. . Many such composite materials are known to those skilled in the art of industrial materials; for example thermosetting or thermoplastic resins or suitable materials such as ceramics or metals. The bonding substrate contains materials such as carbon, boron, glass, aramid, metal, and polyolefin. The material may include fibers selected from one or more of the following reinforced plastics.

The dissimilar material parts of the carrier can be assembled by a person skilled in the art, for example by threaded or adhesive connections. The combination may be made by any known suitable method. The completed carrier formed in this way is preferably a one-piece, generally cylindrical hollow body.

As mentioned above, the corrosive core in the projectile according to the invention is placed in the carrier for firing. It may directly contact the inner wall of the closed rear end of the carrier when filled. as an alternative The carrier and the aft end of the agile body core may be separated by an intermediate member. fungus For example, a nodule may be provided at the rear of the fur. Such a blob hits the target surface Sometimes the corrosive core will be made of heavier material to add even more impact forces.

Alternatively, the nodules can be used to remove chemicals, explosives, It may also have a capsule containing entrained materials such as flammable agents. outside the capsule like this The sides may be made of collapsible plastic material or composite material or metal walls, for example. stomach.

The shape of the rear end of the core may include a recess, e.g. a spherical or conical cavity into which the nodule enters. Conveniently, it is contained so that the nodules are accommodated.

The carrier carries, in particular at its rear end, e.g. any tracer known to the person skilled in the art. You may.

Unlike the current series of armor-piercing bullet discard plate (APDS), the carrier must be Starting the mother machine from Ya was not successful. Obtained by the combination projectile of the present invention The advantage of the improved motherboard method is that the projectile itself is made of wood, e.g. The same effect can be achieved even if it is used as a secondary projectile part for large bullets, including.

In any case, the projectile according to the invention has a rotating shaft which gives the projectile adequate flight stability. suitable means known to those skilled in the art for engaging the gun's rifling barrel for applying torque. It is also possible to provide steps.

Preferred specific example As shown in Figure 1, a full-caliber projectile embodying the present invention has a sawtooth shape and its symmetry. is very similar to that of a normal projectile, but in a known projectile with a relinquishing bottom plate. Provides benefits not previously available. The main parts of this new projectile 10, namely The main parts are an elongated carrier 11 that can be made from mIr, and a tungsten alloy or radioactive material. 12 and a thin pointed shield nose 1 attached to the front end of the carrier 11. 3. The shield nose part 13 shall be made of plastic or aluminum. is also possible, but in any case it is preferable that it be lightweight. From FIG. 1, the core 12 is A point that is not in the same or perpendicular plane as the leading edge 15 of the carrier 11 provided with the inclined part. It can be seen that it has a forward end in the shape of a nose 14. The core nose part 14 is the carrier 1 1 rather than intentionally shifted rearward in the direction of flight 25 of the projectile 10. will be placed. The tip of the nose 14 is sharp when fired from a gun (not shown). Preferably, it is located approximately at the same position as the starting point of the slope forming the leading edge 15. child The reason for the relative placement is to generate the following continuous event, and the projectile 1 It is based on the interaction phenomenon between zero and the collision surface.

The sharp annular leading edge 15 of the carrier 11 provided with an inclined portion causes the sixth A stress field is generated within the target 50 as shown.

They are synthesized while the stress waves propagate through the target material and are The wave amplitude will be amplified to a much greater extent than the waves formed (Figure 10). 6), this stress field within the target 50 material is caused by the sharp leading edge 15 of the carrier 11. It is further amplified by the core 12 hitting the target 50 at the center immediately after the initial impact. Ru.

The target material cannot withstand this rapidly increasing stress load, leading to failure. this On the other hand, a normal projectile carrier 20 as shown in FIG. , generating a series of stress waves within the target as shown in FIG. 10 does not strengthen the waves.

When a projectile embodying the invention is fired from a gun, the expanding propellant gas is emitted. A propulsive force is applied to the bottom of the projectile, and this force causes the rod mother body core 12 to move as shown in Figure 1. Press it to the rear position of the carrier 11. When there is a tIA collision, there is a thin sky. The pneumatic shield 13 is easily disassembled. The leading edge 15 with a slope is the target 50, the projectile 10 is rapidly decelerated during the initial penetration process and loses its motion. High-density rod infiltrator core 1 slidable in carrier 11 due to sudden restriction of volume 2 is suddenly moved forward and applies a second wave of impact stress as shown in FIG.

As a result, the slanted leading edge 15 of the carrier 11 initially generates The stress field is created by a second series of impact load stresses generated in a concentrated manner within the same field. The overall effect is similar to "one-two bunch", which is the action of the mother machine mechanism. It is far more destructive than a single punch.

The projectile shown in Figure 2 is similar in shape to the projectile in Figure 1, but the specific example in Figure 2 is A rod is provided in the shield 13 and the rod penetrator core 12 and the front part of the carrier 11 are connected to each other. The difference is that it is designed to contain 1G of surrounded pyrotechnic agent. Figure 1 and In both embodiments of Figure 2, as will be readily apparent to those skilled in the art, the bottom of the carrier body A known tracer (not shown) can be easily included within.

Figure 3 shows a 0.50-inch diameter (12.7 shoe) according to the prior art currently in use. ) shows the current armor plate carrier projectile 20. This is inside the aluminum bottom carrier 22. It consists of a high density material core 21 arranged in a. The forward part of the projectile is positive The filler material contains either a filler material such as a filler material or a combustible material 23. The entire structure is made of thin gold plated gold. It is surrounded by a metal sheath 24. Unlike the present invention, in the case of the prior art projectile 20, the Of the parts, only the core 21 is used in the target penetration process.

As mentioned above, the present invention can be used in a wide range of firearms, from pistols to large-caliber guns. , the shape and dimensions of the projectile are also intended to vary depending on the application. but The advantageous motherboard phenomenon, as described above with respect to FIGS. 6 and 7, is that the individual The size and shape will be adapted to each geometrical enclosure. Various ranges currently in use As an example of a projectile in the range of It has a projectile with a small diameter ratio, but this is mainly used when wearing bulletproof vest-type clothing. intended for people. This allows for a larger diameter-to-diameter projectile, which Offers a longer rod core that provides greater mass and higher trajectory effectiveness for the mother aircraft. provide This is entirely appropriate since large caliber projectiles are intended for material destruction. . The current GAU-8 armor plate carrier launch suspension 30 shown in Figure 4 is designed to form a projectile shape. It consists of a high-density material rod core 21 surrounded by an aluminum material 32. . Upon impact with the target, the aluminum windscreen 33 is easily destroyed and exposed to high The density rod 31 is made agile towards the target. This action only generates the cover turn in response to the first stage bus. It is impossible to destroy the durable and durable armor plate system. A projectile embodying the invention is , has a similar overall shape to these known projectiles.

Figure 5 shows the current Feldman patents (U.S. Pat. No. 3,714,900 and No. 3.905.299) shows one form of a relinquished bottom plate projectile. Gun muzzle ( (not shown), in order to direct the inner core 41 toward the target and continue the flight. The bottom plate members 42, 43 and the windshield 44 must be abandoned. child This will reduce the ballistic resistance, but if you fail to abandon the component, the resistance will become extremely strong. It becomes a big thing. Unlike a single integral bottom plate, a bottom plate subassembly must be manufactured. In addition to being expensive and requiring multiple parts, there is a risk that the performance will be significantly reduced with a multi-part bullet bottom plate. There is a risk. Therefore, the bottom plate of a bullet is During this process, an asymmetrical force is applied to the core 41 in an angular or lateral direction that disturbs the trajectory even slightly. Everything must be abandoned so that it is not loaded. What in abandon like this If a slight aerodynamic turbulence occurs, the mother aircraft may miss the distant target or reduce the angle of impact. changes, and the agility effect is lower than the optimal design condition. In contrast, the firing according to the present invention The body has no dead weight to give up, is not subject to significant resistance forces, or is unable to engage in agile processes. A bullet abandonment mechanism that does not have any non-contributing parasitic components and is extremely sensitive and unreliable. There is no decrease in accuracy due to

Another embodiment according to the invention, shown in FIG. Excessive impact force beyond the gun's design value may be applied and damage the weapon. , used to limit the recoil force applied to the gun barrel within a narrow range. all guns To accelerate the projectile to armor plate penetration without exceeding impact design limits. Therefore, it is desirable to reduce the mass of the projectile. Therefore, in the embodiment shown in FIG. , instead of the single integral mass shown in Figure 1, the carrier 11 is divided into two parts and the mass We are trying to reduce this.

The modified example in Fig. 8 is two structural joint parts 26° made of different materials, one rear part 1 8 is aluminum, reinforced plastic, i.e. glass fiber or metal fiber and plus Lightweight materials such as layered reinforced lightweight composites with ticks, ceramic and non-metallic materials made from.

Part 26.18 may be a threaded joint, a variety of epoxy-based super adhesives, or a the boundary by appropriate means such as other assembly methods widely used in the two industrial fields. It is joined to the upper part at part 19. This mass body is formed as shown in Fig. 1. In the same way that the carrier 11 encloses and holds the core 12, the heavy high-density agile core 12 with a sliding fit.

FIG. 9 shows another modified embodiment of the structure according to the invention. In this case, the mass body is shown in Figure 1. Instead of a single homogeneous core 12 as shown, it is made of a front core 12 and a rear member 17. It is composed of multiple members. The core 12 has a conical shape as a whole and has a pointed nose portion 14. The core 12 of FIG.

The member 17 at the rear of the core 12 is made of a different material than the core 12, but is made of a different material than the core 12. Depending on the combat purpose used, heavier or lighter versions are used. For example, projectile 1 When G collides with the target surface, the core 12 should be assisted to apply a larger impact force. Alternatively, member 17 may be an elongated blob of material that is heavier than core 12. Core shown in Figure 9 12 has a concave shape such as a sphere or a cone in the rear part, that is, the bottom part on the opposite side from the nose part 14. A section has been established. The member 17 is inserted into the rear cavity within the core 12 as shown in FIG. any shape, either spherical or conical, that curls up and makes symmetrical contact with it It has a forward end having a shape. Alternatively, the member 17 may be a droplet filled with entrained material. Possible plastic, composite or metal capsules. of accompanying materials The exact composition depends on the combat purpose of use. Therefore, the member 17 is, for example, a carrier. After the carrier 11 and core 12 carry out the mother aircraft, it will be scattered in the crew cabin etc. It may also contain accompanying materials such as chemicals, non-drugs, and flammable agents.

In the embodiments of the present invention described above, the agile body core 12 has a pointed nose portion 1. It has 4. Both nose portions 14 are shown to be made of the same material as the body of core 12. However, for the core 12 body made of tungsten alloy or radiant superlan, It may have a tip of a different material, for example steel.

In the specific examples shown in FIGS. 11 to 15, the agile body core 1 has various alternative shapes. 2 is shown, but in both cases, in front of the core 12 there is a The pointed nose 14 shown is replaced by a sharp annular leading edge 64.

During ~ In FIG. 11, the core 12 is tubular, with inclined surfaces 65 on the inside and outside of the tube at the leading end. 1t64 is formed.

In FIG. 12, the shape of the core 12 is similar to that shown in FIG. The difference is that only the side portion 66 is tubular. In this case the core 12 is the solid rear part 6 1. As shown, the rear section 61 is made of, for example, a heavier material than the front section 66. and may be made of different materials.

In FIG. 13, the shape is similar to that shown in FIG. 11. However, in this case, the tubular A 12 contains a rod 68 with a slip fit within the core 12. when a projectile is fired , the core 12 itself is set rearward within the carrier as described in FIG. Similarly, the rod 68 is set rearwardly within the bore of the core 12. For this reason, the carrier 11, the tubular core 12 and the rod 68 are in this case a two-stage passage as illustrated in FIG. Unlike Cheng, it works to provide a three-stage target motherboard process.

In FIG. 14, an annular leading edge 64 is provided at the front of the conical portion 69, and the edge 64 is connected to the core. An acute angle is formed by a groove portion 61 machined in the front of 12.

The embodiment shown in FIG. 15 is similar to that shown in FIG. 14, except that in FIG. The difference is that the body of No. 2 is tubular. An alternative example similar to the example shown in FIG. (none), only the rear end of the core 12 may be tubular.

In the embodiments shown in FIGS. 11 to 15, the core 12 is shown in FIG. The nose part 13 is also fitted into the carrier 11 as shown in FIG. It is placed in front of 1.

In all embodiments of the invention, the cavity within the nose section 13 is filled with materials other than flammable agents (as described above). It may also be used to fill with effective entrainment materials.

The projectile according to the present invention fired from the barrel of a gun is given spin rotation even when it falls down. flight becomes stable. The carrier (e.g. The shell 11) may include suitable means for engaging the rifling barrel of the gun, e.g. You may also use a known drive band or button/obturator. stomach.
