Definitions

  • the invention relates to a penetrator consisting of a high-strength shell and arranged in the interior of the shell explosive charge, comprising a voltage applied to the inside of the shell, against external influences protective layer, which starting from the tip of the penetrator at least over a part of the rear extending jacket of the penetrator extends.
  • Penetrators are known active ingredients which are used in particular for the neutralization of so-called high-value targets. These include strongly hardened structures or objects, such as command centers or communication centers.
  • the penetrators are capable of penetrating the target, optionally using a drive for further acceleration. The initiation takes place with the help of intelligent ignition devices inside the target, whereby the destruction of the target can be brought about.
  • the layer is embodied as a layer which dampens shock waves acting on the jacket by means of deformation, the wall thickness of which decreases starting from the tip or remains constant.
  • damping measure it is advisable to arrange one or more damping layers with a respective thickness of several centimeters transversely to the longitudinal axis of the penetrator in the explosive, this measure, in combination with that already described, along the Inner side of the shell extending damping layer, or has proven to be excellent as a sole damping layer in the case of oblique impact of a penetrator on a target.
  • a further advantageous embodiment of the damping measure is to bring the explosive or at least the part thereof, which is heavily loaded, in the form of balls of different sizes (a few centimeters to a few 10 cm, depending on the size of the penetrator) in the interior of the penetrator ,
  • the penetrator jacket can already be provided on the inside with a damping layer.
  • an arbitrarily dense sphere packing is to be sought, which can be adjusted to the desired size with the help of the ball size distribution.
  • This measure can be matched to the expected bending loads of the penetrator.
  • the cavities are filled with the said damping means, in which the explosive balls are embedded. Bending motions and associated compressions and strains are thus captured by the damping matrix and kept away from the macroscopic explosive spheres altogether.
  • porous material for the cushioning layer or damping means which, by deformation due to the introduced shock wave energy and its conversion to heat, largely assists the cushioning effect.
  • Suitable materials are plastics, ceramics or metals also in the form of foams, powders or hollow spheres.
  • This effect can be further increased by skillful combination of at least two different damping materials or damping means.
  • the greatest effect can be achieved by the clever choice of the impedances of the damping layers or damping means among themselves by the adjustment between the two impedances is set as bad as possible. This leads to reflections of the shock waves within the damping material, in which a essential part of the energy is consumed. If the material is still porous, energy is dissipated as desired in each pass.
  • shock waves 8 propagate in the interior 2 of the penetrator. Since the interior is usually completely filled with explosive 3, the shock waves act directly on this. While in an uncovered explosive charge axially coupled shock wave pressures are immediately reduced by laterally incoming dilution waves and thus the dynamic pressure load is reduced, run in the case of the penetrator, the shock waves 8 even in the shell 1, so that no laterally incoming dilution waves can enter the explosive charge. In the explosive, the initiation threshold is lowered by up to a factor of 4 due to this effect, thus significantly increasing the detonation sensitivity. This greatly increases the risk of premature detonation.
  • FIG. 2 shows the penetration of the penetrator into a target 7 at an angle to the solder on the target surface. This case is most common in practice, so that the consequences for the concept of a penetrator are relevant. With oblique impact and asymmetric penetration, the penetrator can be bent. As a result, locally both compressions 9 and dilutions 10 occur in the explosive.
  • FIG. 3 shows a proposed solution with the aid of which the mentioned effects can be avoided or at least reduced to an order of magnitude which is no longer harmful to the explosive charge.
  • the proposed measure involves the integration of damping means within the shell 1 of the Penetrators P. These can be designed as circumferentially disposed within the shell 1 damping layer 4.
  • the wall thickness of this layer can be constant or, as shown in the exemplary embodiment, be most pronounced in the region of the tip 5 and decrease in the direction of the tail 6.
  • a compound of the shell with the damping layer 4 by means of an adhesive supports their effect.
  • the damping layer is made with the aid of suitable materials which have a damping effect against the shock waves.
  • these materials should be porous in order to convert kinetic energy into heat when exposed to shock waves by closing the pores (energy dissipation). This process is indicated in FIG.
  • the shock wave 11 penetrating from the tip of the penetrator is considerably reduced in intensity as compared with the situation illustrated in FIG. 1 with the aid of the region 4a of the damping layer. Since this takes place by means of compression of the damping layer, no pores are shown in the damping layer for clarification in this area.
  • Porous plastics and rubber materials may be mentioned representative of porous plastics and rubber materials. Porous ceramics, foams and metals as well as metal powders or metal or glass spheres are also suitable. Through skillful combination, the skilled person receives a wide selection of possible damping layers, which can be matched in their porosity and impedance to their needs.
  • FIG. 4 shows a further possibility of attaching further compressible damping layers 12 in the interior of the penetrator in order to support the damping layer 4 arranged along the inside of the jacket 1.
  • damping layers are transverse to the longitudinal axis of the penetrator and divide the interior 2 into several spaces that are completely filled with explosives.
  • the damping layers 12, 13 in the case compensate for the deformation of the penetrator jacket in the event of an oblique impact on a target 7 .
  • the damping layers 13 are already compressed in the embodiment by the deformation so far that the available pores are already closed.
  • These damping layers must therefore have a certain minimum thickness D in order to compensate for the paths required for compensation and at the same time to dissipate energy by deformation. According to the invention, therefore, a thickness D of a few centimeters for the damping layers 12, 13 is provided. Substitution of the damping layers by thin separation layers does not bring the desired success. With the help of the proposed thickness of the damping layers deformations of the explosive charge and the associated pore formation in the explosive are avoided from the outset. At the same time the further transport of shock waves in the respective adjacent segment of the explosive charge 3 is avoided.
  • FIG. 6 shows a further variant of the invention.
  • Part of the explosive which is in the area of the penetrator which is subjected to the greatest load, is arranged in the form of spheres of different sizes (a few centimeters to a few 10 cm, depending on the size of the penetrator) in the interior of the penetrator.
  • the jacket of the penetrator can already be provided on the inside with a damping layer 4. It is desirable to have any density ball packing, which can be adjusted to the desired size with the help of the ball size distribution. This measure can be matched to the expected bending loads of the penetrator.
  • the cavities are filled with a damping means 14, in which the explosive balls 15 are embedded.
