Definitions
- the present invention relates to a projectile for fighting lightly armored targets.
- a projectile serves to create an active body, which is able to break it up when hitting a hard target and to act inside the target by splintering.
- the projectile must be designed so that it can act on the armor of the target in such a way that the actual penetrator of the projectile can pass through the armor, or at least the penetration is facilitated.
- This effect on the armor takes place through the kinetic energy of the penetrator contained in the projectile.
- DE 197 00 349 C1 discloses the mode of action of a projectile construction for fighting armored targets. It discloses various expander media whose purpose is to break up a projectile body when hitting a hard target and form splinters, while a subsequent penetrator breaks through the armor of the target.
- a projectile which has a projectile body of a harder material than the expander material inside the projectile body.
- expansion medium and projectile body are decelerated.
- the penetrator mounted in the projectile body behind the expansion medium compresses the expansion medium due to its kinetic energy and breaks up the projectile body into splinters. Due to its high kinetic energy, the penetrator continues on its way through the armor. At least part of the fragments formed from the projectile body follows the penetrator through the firing channel and acts within the target.
- various materials are proposed, all of which have in common that the density of the expansion medium is lower than that of the shell or the penetrator.
- the materials described in the aforementioned document as Aufweitmedium are quite expensive and often associated with high effort in the production.
- Object of the present invention is thus to provide a projectile for fighting armored targets, which is inexpensive to manufacture and manufacturing represents the least possible effort. It is also an object of the present invention to achieve a high level of active safety.
- a projectile which extends in the longitudinal direction.
- the projectile has a projectile tail, which at least partially accommodates a projectile body.
- a penetrator is provided, which is mounted within the projectile body so that it is longitudinally movable.
- a ballistic hood is still provided at the end of the projectile body, which protrudes from the bullet tail. This is called the front end. At the other end, the rear end, is the bullet tail. At the rear end of the projectile body, an envelope of ductile material is preferably provided, which comprises the projectile body, closes to the rear and takes over the guidance of the projectile body in a weapon barrel. The front end of the projectile is formed by a ballistic dome.
- the hood which is mounted in the direction of flight of the projectile at the front end, ensures good aerodynamics of the projectile and thus good flight characteristics.
- the present invention is characterized in that metal foam is proposed as expansion medium within the projectile body.
- metal foam is proposed as expansion medium within the projectile body.
- the penetrator and the expansion medium is stored within the projectile body.
- Foamed metals, especially closed-cell, air-foamed aluminum, have several advantages over the already known materials as expansion medium. The advantages include low density, good formability and favorable production by foaming, forming or cutting from sheet material.
- the hood Upon impact of the projectile according to the invention on a target, the hood first breaks away from the projectile or shears off from it.
- the hood has no further effect when penetrating an armor, but is only intended to improve the ballistic flight characteristics of the projectile.
- the bullet body hits the target to be hit.
- the expansion medium disposed in the projectile body also impinges on the target and is compressed in the direction of the target by the abrupt braking of the projectile. This compression is further enhanced by the also positioned in the projectile body penetrator, since this has a higher density than the expansion medium.
- the projectile body preferably penetrates into the target at least in regions, so that the projectile body forms a closed unit with the target, which encloses the expansion medium.
- the projectile body is made of a material of high density and this offers the Aufweitmedium no opportunity to escape from the projectile body when impacting on a target, the expansion medium is compressed in the direction of the target. By this compression of the projectile body is broken.
- metal foam such as aluminum foam
- the expansion medium has the surprising advantage that the fluid which is bound in the pores of the metal foam is also compressed in the direction of the target, up to the plasma formation.
- the energy of such a compressed fluid supports the breaking up of the shell body.
- This plasma formation ensures a high level of active safety.
- An expansion medium made of aluminum foam thus exhibits slight deformability under the movement of the penetrator when hitting a hard target.
- the trapped fluid is compressed until it forms a plasma and acts on the projectile body so that it deforms and / or breaks up.
- air is proposed as the fluid.
- a break-up of the projectile body is prevented when the projectile impinges on a soft target.
- the expansion medium can not be compressed far enough either by the soft target, so that no fragmentation takes place in a soft target.
- the material of the projectile body has a higher density than the expansion medium.
- the material of the penetrator has a higher density than the expansion medium.
- the material of the projectile body has a higher density than the hood of the projectile.
- the penetrator is made of tungsten or a tungsten alloy, since tungsten provides high strength and forms a proven material for penetrators.
- tungsten-containing substrate is also conceivable.
- the propellant is in contact with the primer and can thus be ignited by the primer cap.
- the propellant charge is propellant powder, such as ECL.
- FIG. 1 shows a schematic cross section through a cartridge with a projectile according to the invention.
- the cartridge comprises a projectile 9 according to the invention, has a sleeve 2 and a primer cap 1, which is arranged at one end of the sleeve 2 of the projectile 9.
- the primer cap 1 is thus arranged at the rear end of the sleeve 2 in the direction of flight.
- the primer 1 is arranged inside the sleeve 2 so that it is accessible from outside the sleeve 2 in order to be ignited by suitable means.
- Suitable agents in the context of the present invention are, for example, agents for the mechanical action on the primer cap 1.
- the projectile 9 according to the invention has a projectile tail 4, which at least partially accommodates a projectile body 6.
- the bullet tail 4 is enclosed in the cartridge-shaped form in the sleeve 2 and that seen at the opposite end of the projectile 9 from the primer cap and thus in the direction of flight of the projectile.
- a penetrator 5 is mounted within the projectile body 6 and an expansion medium 7.
- the expansion medium 7 has a lower density than the penetrator 5 and the projectile body. 6
- the projectile 9 also comprises a hood 8, which is arranged at one end of the projectile body 6. In this arrangement form in the longitudinal direction hood 8 and the end of the sleeve 2, on which the primer cap 1 is mounted, the two ends of the cartridge.
- expansion medium 7 As expansion medium 7, a metal foam is provided, since this has a low density, is inexpensive to manufacture and has a simple production.
- the propellant charge 3 of the sleeve 2 may consist of propellant charge powder and is in contact with the primer cap 1. This makes it possible to ignite the propellant charge 3 by acting on the primer cap 1. By means of suitable ejection openings, the gas produced by the ignited propellant charge 3 can escape from the sleeve 2 and drive the projectile.
- the projectile 9 is driven by the propellant charge 3 and thus accelerates the projectile body 6 held in the projectile tail 4.
- the propeller 8 enables the projectile to be aerodynamically propelled.
- the hood 8 is not required for the effect of hitting the target and is therefore designed so that upon impact, the hood 8 breaks away or shears off.
- the projectile 9 according to the invention hits the target with the projectile body 6 and at least partially penetrates into the target in the case of a hard target. Due to the partial penetration of the projectile body 6 in the hard target or the armor, the expansion medium 7 is enclosed within the projectile body 6. The expansion medium 7 is also decelerated in the direction of the destination, namely by the abrupt change in speed at the destination and by the deceleration of the penetrator 5, which also pushes the expansion medium 7 in the direction of the destination.
- the penetrator 5 can also move in the direction of the target, wherein it deforms the expansion medium 7 and compacted. As a result of this compression, the expansion medium 7 continues to deform the projectile body 6 so that it builds up and deforms or bends the target, with the aim of penetrating the armor of the target.
- the fluid contained in the pores of the metal foam is also compressed, up to the plasma formation.
- the projectile body 6 is further deformed, right up to the breaking up of the projectile body 6.
- the present invention is not limited to the aforementioned features. Rather, further embodiments are possible.
- the expansion medium itself forms the hood and thus manages the bullet without its own component for the hood. Accordingly, the hood can be made in one piece from the expansion medium or as a separate component.
