Definitions

  • the innovation relates to a detonator for the explosive charge of a penetrator, the explosive charge consists of at least a partial charge and an insert, which is disposed within the shell of the penetrator, wherein the igniter is fixedly mounted on the rear () of the penetrator and connected to a booster charge.
  • Penetrators are active systems which, due to their structural design, are suitable for penetrating resistant structures such as building walls made of brick or concrete or even rock.
  • penetrator equipped with a hollow charge When combating such structures by a penetrator equipped with a hollow charge, the effect of the directed hollow charge is no longer in the foreground. Rather, it is of interest that the penetrator after penetrating the structure is able to develop in the space behind the structure as high as possible blast and / or splintering performance. Otherwise, the mission can not be adequately fulfilled.
  • the innovation is based on the problem that on the one hand high-strength and thick structures must be perforated. This requires fast and slim penetrators with a corresponding explosive charge associated with a liner and an upstream cavity in the tip of the penetrator. On the other hand, experience the penetrator and thus the explosive charge in the perforation a very high negative acceleration, which causes the explosive charge moves due to the everting of the insert to Penetratorspitze out. This movement of the explosive charge towards the penetrator tip and away from the ignition device involves the risk that distances, in particular from the booster charge to the explosive charge become too large and a safe initiation of the explosive charge is no longer guaranteed.
  • a further aspect is that the ignition of the explosive charge is relatively far away from the shaped charge insert and, as a result, the detonation wave strikes the shaped charge insert in a grazing rather than frontal manner. This usually leads to power reduction.
  • the novelty is therefore the object of demonstrating a solution that allows a waiver of the support devices described and the formation of detonation fronts result, which supports the spine training and the stinging performance.
  • the object is achieved in that the booster charge by means of a spacer on the longitudinal axis of the penetrator in the direction of the deposit in is arranged at a distance from the ignition device.
  • This solves the problem of bridging a non-explosive filled cavity in a simple manner.
  • the distance of the booster charge to the deposit can be shortened so far that in each case an initiation after the target passage is possible because a frontal impact of the detonation front is ensured on the deposit.
  • a favorable dimensioning is when the resulting in the case of everting the liner before the ignition cavity in its longitudinal extent in the direction of the insert is smaller than the distance L.
  • a particularly favorable effect on the course of the detonation waves is that a detonation waveguide DWL is arranged between the amplifier charge and the insert.
  • FIG. 1 is proposed as a solution to the problem an ignition device in which the booster charge V at a distance L from the conventionally attached to the rear of the shell H of the penetrator ignition Z is arranged.
  • a spacer A in the form of a cylindrical shaped device.
  • the booster charge V is arranged at that end of the spacer A, which lies closest to the insert E in the direction of the longitudinal axis LA of the penetrator.
  • the dimensioning and individual design can be adapted to a large extent to the requirements specific to the respective penetrator.
  • FIG. 2 the function of the igniter with spacers is simplified. If a penetrator like him in FIG. 1 a target is shown penetrating moves the explosive charge SP toward the Penetratorspitze due to the strong delay. Usually, this is a plastic-bonded and thus plastically easily deformable explosive charge, which tolerates such deformations without being stimulated to a reaction.
  • the insert E of the penetrator is supported according to FIG. 1 with its edge on the shell H of the penetrator. However, in the case of a target penetration, it can not stop the explosive charge SP urging in the direction of the penetrator tip. Thus, the insert E inverts and now lies against the inside of the shell of the penetrator. The empty volume HO previously formed by the insert E and the tip of the penetrator is then completely filled with it due to the high pressing pressure in the explosive charge SP. For this, another cavity HR has formed at the rear of the penetrator adjacent to the ignition device Z.
  • the length of the spacer A is now designed so that the booster charge V remains in all cases in the area of the deformed explosive charge SP.
  • the ignition of the booster charge V thus leads to the intentional detonation of the explosive charge.
  • An advantageous embodiment is to make the spacer in the longitudinal extent flexible, so that it largely follows the forward movement of the explosive charge and so in any case the contact is lost to this, whereby a reliable ignition is guaranteed.
  • Such a variable length expansion can be achieved, for example, by a telescopically designed housing, or by a zigzag-folded housing (similar to the concertina effect).
  • This type of spacer housing is not shown in the figures.
  • Other flexible configurations are conceivable by adapted constructions, but should not be further enumerated here.
  • FIG. 3 A further advantageous embodiment is in the FIG. 3 shown.
  • a detonation waveguide DWL or damping element is provided adjacent to the booster charge and in the direction of the insert E. If the penetrator has penetrated into a target and the explosive charge has moved forward, initiation will take place in the same manner as in FIG FIG. 2 has been described.
  • the detonation wave in the explosive charge proceeds as in FIG. 3 dashed lines and designated by the reference numerals 1, 2, 3 shown.
  • the detonation wavefronts deflected by the detonation waveguide DWL are forced radially onto the paths labeled 1, 2, 3.
  • the angle of incidence on the insert E is thus significantly steeper than that of a course without a detonation waveguide DWL, which in the FIG. 4 is shown.
