Definitions

  • the invention relates to an explosive charge for a warhead, wherein the explosive charge comprises an ignition device which contains a first detonating chain with a detonating charge boost charge, which is assigned a further detonating chain with a further boost charge spaced from the first detonating chain and the ignition of the first and the second Boost charge takes place at the same time or at different times.
  • the explosive charge is initiated by means of a detonating chain.
  • the ignition chain consists for example of an electrically ignitable detonator, a transfer charge and a booster charge.
  • the booster charge is dimensioned so that the explosive charge can be implemented detonatively.
  • the warhead described includes the possibility of deformation of the splinter shell, so that an increased effect occurs in a selectable preferred direction. A change in the performance of the explosive charge is not provided.
  • the FR 2561376 A which forms a Kunststoff for the claim 1, describes a warhead with an explosive charge, on the opposite two identical ignition devices are arranged with these associated booster charges. These ignition devices are designed for the detonative initiation of the explosive charge. In the case of their ignition, the detonation fronts in the explosive charge converge towards one another and cause a concentration of the detonative effect in the radial direction relative to the original running direction of the detonation fronts in the region of the impact. The ignition takes place basically at the same time. An ignition at different times is provided, but there is no provision for setting the time interval specified. It is thus achieved an increase in power in a particular direction, a controllable reduction in performance of the explosive charge is hereby not possible.
  • the invention is therefore based on the object to propose a simple and reliable method of target-selectable setting the performance of the explosive charge of the warhead.
  • the inventive form of the ignition device for a warhead the following advantages are achieved.
  • arranging a further ignition chain to the necessary anyway for the detonation of the explosive charge detonating the deflagrative initiation of the explosive charge is possible in a simple and inexpensive manner. If both igniter chains are opposite one another with respect to the longitudinal axis of the explosive charge, the arbitrary adjustment of the deflagrating portion of the explosive charge between 0 and 100% can be achieved by a suitable choice of the two ignition times.
  • the housing 6 may be designed in a known manner adapted to the properties of the warhead. However, this design has no significant influence on the function of the present invention.
  • the explosive charge 1 consists of a homogeneous explosive mass which fills the housing 6 completely over the length L and which requires the initiation of a high energy level (stimulus).
  • the boundary line 7 shown in FIG. 1 between the left and the right half of the explosive 1 is explained below with reference to FIG. 2.
  • a priming chain 2 of known type is attached at the right end side of the housing 6.
  • three-stage igniters consisting of an electrically ignitable detonator, a Studentstragerladung and a booster charge.
  • booster charge 3 acts directly on the explosive charge 1.
  • a further ignition chain 4 is arranged on the opposite end face of the housing 6.
  • This further ignition chain 4 has as amplifier charge 5 a deflagration-triggering device.
  • amplifier charge 5 a deflagration-triggering device.
  • One possible embodiment is, for example, a shaped charge.
  • the further booster charge 5 is dimensioned such that it can only produce an energy level sufficient for the deflagration of the explosive charge 1.
  • the stimulus generated by the further amplifier charge 5 is significantly lower than that of the amplifier charge 3.
  • Fig. 3 shows a graph of the reaction R of an explosive as a function of the level of stimulus ST introduced by the booster charge.
  • a small stimulus ST up to the first dashed vertical line of the deflagration threshold does not produce any reaction with the explosive.
  • An increase of the stimulus ST to values between the two dashed vertical lines of the deflagration threshold and the detonation threshold triggers a deflagration in the explosive. This means that the explosive burns at a reaction rate of about 2000 m / s without producing a detonative blast effect. If the stimulus ST is increased beyond the detonation threshold, the detonation of the explosive takes place at a reaction rate of about 8000 m / s.
  • the illustrated in Fig. 1 further amplifier charge 5 is exemplified as a shaped charge.
  • a so-called EOD (Explosive Ordnance Disposal) hollow charge is used, which is suitable because of their properties, a non-detonative reaction in the To trigger explosive charge.
  • This is achieved by adjusting the thickness of the sting produced by the shaped charge by selecting the caliber of the shaped charge. that the stimulus ST generated in accordance with the diagram in FIG. 3 lies in the region between the deflagration threshold and the detonation threshold.
  • Another possibility of adaptation can be achieved by the preconnection of metal plates or similar acting materials, which reduce the spine effect so that only the deflagration is triggered in the explosive charge.
  • booster charge which is not designed as a hollow charge
  • the diameter of the booster charge in the region of the so-called critical diameter, so that the booster charge 5 itself only reacts in the form of a deflagration and thus in the explosive charge 1 only a deflagration triggers.
  • FIG. 2 shows, by way of example, the course of a warhead ignition, in which only 40% of the total power of the warhead is to take effect.
  • the geometric arrangement of the explosive charge corresponds to the representation in FIG. 1.
  • the vertical dashed line 7 represents the boundary between the explosive component 1 a to be ignited detonatively and the explosive component 1 b burning deflagratively. Since the rate of initiation during detonation is approximately four times as high is like the burning rate of the deflagration, the deflagration triggering ignition chain 4 must be started when approaching the warhead to a target first. Only after a delay time ⁇ t is the ignition chain 2, which triggers the detonation, initiated.
  • the time difference At is characterized by the difference in the propagation times t v of the deflagration to the boundary line 7, and the transit time t o of the detonation front to the boundary line 7.
  • the time difference ⁇ t is 250 ⁇ s.
  • the ignition chain 2 must be triggered delayed with respect to the further ignition chain 5 in order to achieve a reduction of the warhead power by 60%.
  • the missile which carries the warhead, flies only a few inches, so that the detonation time, which is determined by means of integrated in the missile ignition sensor, it is not significantly affected.
  • the detonation must also be initiated before the deflagration if necessary. In each case, depending on the percentage of the desired effect, it is possible to determine a certain delay time ⁇ t with which the detonation is initiated after deflagration or vice versa.
  • the solution according to the invention also makes it possible to retrofit existing warheads with a detonating chain 5 to initiate a deflagration. If the construction and the spatial accessibility allow it, such a device can be added to each existing warhead retroactively to the explosive charge.
  • the existing ignition system is then extended by a second ignition output whose ignition signal is offset in relation to the ignition signal for the detonation release accordingly.
