Definitions

  • the invention relates to an Eplosively Formed Projectile (EFP) charge for producing a penetration projectile, in the initial state in the center of a lining of the (EFP) charge (L) oriented in the propagation direction of the detonating (EFP) charge component (B) at least one in the goal almost ballistically ineffective expansion material (AWM) low compressibility is arranged, which forms the rod-shaped core of the means of triggering the (EFP) charge (L) formed Penetration projectile, and at least one core surrounding the core radially (M) of a in the target ballistically effective further material, wherein the shell (M) of the Penetrationsgeunteres from at least a portion of the lining of the charge by triggering the (EFP) charge (L) is formed and connected to the core, and wherein the materials of the core and clearly differentiate the envelope in terms of density.
  • EFP Eplosively Formed Projectile
  • Projectiles or warheads are always designed so that they develop the greatest possible specific effect in the respective target. Depending on the field of application, a high penetration power or the greatest possible areal effect for increasing the efficiency is thus sought. As long as objectives can be assigned to hard or light target classes, it is sufficient to design the projectiles or warheads accordingly.
  • the rod-shaped projectile consists of a shell, which is advantageously made of metal or heavy metal.
  • the interior space is filled by a so-called expansion medium (AWM), which is selected from a number of suitable media having specific properties.
  • ABM expansion medium
  • Necessary is a significantly lower density than the material of the shell and at the same time a low compressibility.
  • PE polyethylene
  • GRP glass fiber reinforced plastic
  • aluminum is polyethylene
  • the specific design of such projectiles depends on parameters such as target material and actual impact velocity, but also on the desired expansion effect.
  • PELE Penetrators A major disadvantage of the PELE Penetrators is that to accelerate a corresponding accelerator such as a cannon is necessary. Due to the system, this also limits the maximum achievable speed to values in the order of magnitude of approximately 2000 m / sec.
  • the FR 2 655 719 A which forms a basis for claim 1, describes the production of a hard core projectile from a hollow charge with a plurality of successively arranged and spaced-apart deposits.
  • the shock impedances of the internally successive deposits is constant or decreasing.
  • the creation of a PELE bullet is not provided.
  • the invention has for its object to develop a penetration projectile, on the one hand requires no such accelerometer and on the other hand can be accelerated to speeds ⁇ 2000 m / sec and its range of uses includes other applications.
  • the solution of this object according to claim 1 is that the component has the shape of a rod, and that the component consists of a first part and another part, which are arranged axially behind one another in the propagation direction of the detonating (EFP) charge, and that the second part has a significantly higher density of the material than the first part.
  • EFP detonating
  • the core of the Penetrationsgeunteres is already given as a component and connects after the detonative triggering of the (EFP) charge with the lining material coming from the lining to the desired Penetrationsgeunter, which consists of materials of different densities and which is accelerated to a speed of ⁇ 2000 m / sec.
  • the target can be perforated, so that the subsequent material can spread better in the lateral direction.
  • the component forming the core of the penetration projectile has, for example, the shape of a rod. This ensures that not only rotationally symmetrical penetration projectiles can be produced by means of the invention, but also that plate-shaped penetration projectiles can be formed by means of a charge stretched perpendicularly to the weft direction. Thus, the application of the invention can be significantly expanded. In addition to the perforation of the target can be alternatively achieve a cutting action.
  • the different in their properties parts of the core are preferably arranged one behind the other, wherein the front in the propagation direction of the detonating (EFP) charge part has a significantly higher density of the material than the subsequent part, or vice versa, if still fiercer targets / structures combats should be.
  • EFP detonating
  • a third part of the core is arranged between the middle part and the lining, the material of which is effective in the target in a special way, for example as a fire load.
  • Claim 3 relates to a method of producing a penetration bullet made of different materials using an Eplosively Formed Projectile (EFP) charge with a shaped lining, which has at least one layer of material (M, M1) suitable for target penetration, and one in the region of Central axis of the liner fixed rod-shaped component (B) of at least one in the target almost ballistically ineffective expansion material (AWM), which is characterized by low compressibility and lower density than the material (M, M1) and in the propagation direction of the (EFP) charge at least a before and / or behind fixed additional material (M2, M3) and in which by initiation of the (EFP) charge the projectile is detonatively shaped in such a way that the material (M1) the expansion material (AWM) and at least one further material (M2, M3) surrounds and is firmly connected to the latter, the formation of the projectile starting from the center of the lining, starting from the entire lining material (M, M1).
  • EFP Eplosively Formed Projectile
  • a component is used for example in the form of a rod. This also rotationally symmetric penetration projectiles can be generated.
  • At least one further layer of a material suitable for the target penetration further material which is introduced between the second material and the explosive charge, thereby a penetration bullet can be generated, which has a penetrating core inside, which is surrounded by the expansion material to ultimately, the sheath is made of a higher density material than the AWM material.
  • This concept combines good penetration properties with high lateral performance.
  • FIG. 1 The functional principle of a PELE rod (penetrator with increased lateral effect with the shape of a rod) is based on the FIG. 1 explains, in which the processes during the impact of a penetration projectile at the speed v on a target Z is shown.
  • the projectile is decelerated in a known manner to the crater ground speed, which depends essentially only on the ratio of the density of the materials of target Z and the projectile AWM, M.
  • the core of the projectile consists of a bulking material, abbreviated to AWM, lower density than the shell M, the crater ground speed of the AWM is lower than that of the shell M.
  • the decomposition can be done in natural splinters with purely random size distribution or by means of controlled decomposition into defined fragment sizes. During the decomposition, the generated splinters are additionally impressed with a lateral velocity in addition to the existing axial velocity and thus a notable lateral effect is achieved.
  • such a penetration projectile is generated by means of the detonation of a charge and simultaneously accelerated to a speed of ⁇ 2000 m / sec.
  • Usable types of charge are in addition to the shaped charges also EFP charges (explosively shaped projectiles) and hemispherical charges. By appropriate design of the individual charge types different projectile shapes and services can be generated.
  • the two-dimensional drawn (EFP) charge L can be designed as a rotationally symmetrical, oval, pyramidal or channel-shaped, planar charge.
  • the expansion material AWM is arranged as a separate component on the symmetry and weft axis of the liner M and fixed in the center of the liner M.
  • the expansion material AWM is shaped as a rod, for example, depending on the design of the (EFP) charge L.
  • the metallic lining M is likewise designed either as a calotte or in the form of a plate.
  • the explosive charge HE has at the apex an igniter ZD. After its release, the detonation front spreads around the optionally provided detonation waveguide D in the direction of the lining M, which is accelerated from the outer edge by means of a forward folding in the direction of the expansion material AWM.
  • the expansion material AWM come in a known manner polyethylene, aluminum or glass fiber reinforced plastic in question, but also other plastics or metals with low density and low compressibility.
  • the lining material M known materials such as copper, tantalum, molybdenum, bismuth and also corresponding alloys can be used.
  • EFP electrostatic pressure
  • the formation process of the penetration projectile proceeds differently than with the collapse of a hollow charge or with a deformation or eversion as with an EFP charge. Rather, this is the process of so-called plating applied, in which two corresponding plates or similar structures by means of initiation of an explosive charge HE are shot at a high speed at a predetermined angle to each other. When they meet, there is a close and well-adhering connection at the contact surface, since due to the high pressures generated, a local hydrodynamic intermingling of the materials takes place. This process can be applied in the same way even with rotationally symmetrical linings as here in the embodiment.
  • the thickness of the lining material M also determines the thickness of the shell M around the expansion material AWM of the projectile during the formation process of the penetration projectile.
  • the rear part of the expansion material AWM is thereby enclosed by the material M of the lining while in the dimensioning of the diameter of the lining chosen here in relation to the length of the expansion material in the weft direction the front of the expansion material is not covered by the material M of the lining.
  • the height of the velocity v (cf. FIG. 1 ) can be influenced, for example, via the opening angle of the lining M and via further geometric parameters.
  • FIG. 3 an embodiment according to the invention is shown.
  • a further material M2 is arranged on the front side of the expansion material AWM.
  • the density of the further material M2 is chosen to be much higher than the density of the expansion material AWM.
  • the material M1 of the lining encloses the core of the penetration projectile, which consists of the expansion material AWM and the other M2 mass exists.
  • the advantage of such a penetration projectile is that by means of the upstream mass M2 first the target wall is penetrated and the expansion process can then take place unhindered.
  • FIG. 4 An example of a further advantageous embodiment of an (EFP) charge according to the invention is shown in FIG. 4 played.
  • the further material M2 is arranged in the weft direction behind the expansion material AWM.
  • the further material M2 is enveloped by the material M1 of the lining.
  • the further material M2 is conveyed to the target during the target impact and the subsequent expansion process. Therefore, a material with properties that are particularly effective in the target is usually used for the further material M2.
  • a magnesium compound can be used as a fire load in the target.
  • M2 can also consist of conventional rod material, if the penetration of other target walls is required.
  • the FIG. 5 shows a further variant according to the invention to the already proposed charges.
  • the component B thus has both a material M3 in front of the expansion material AWM and a further material M2 between the expansion material AWM and the lining M1.
  • the properties of materials M2 and M3 are generally different.
  • the weft-facing material M3 will usually be designed for optimum penetration of the target, and the backsheet M2 preferably for use within the target, including both the penetration of other target walls as well as the initiation of a fire.
  • the materials M2 and M3 will be designed as a metal cylinder or cuboid, which are firmly connected on the one hand with the expansion material and on the other hand with the liner.
  • the expansion material in between corresponds in its properties to the already described above with low density and low compressibility.
