Definitions

  • the invention relates to an ignition device for a warhead with a Explosive charge that detonates an ignition chain with an amplifier charge Initiation of the explosive charge contains.
  • a warhead is known from the publication DE 41 39 372 C1 whose explosive charge is initiated with the help of an ignition chain.
  • the ignition chain consists, for example, of an electrically ignitable detonator, a transfer charge and an amplifier charge.
  • the booster charge is dimensioned so that the explosive charge is implemented detonatively can.
  • the warhead described includes the possibility of one Deformation of the splinter jacket, so that an increased effect in one selectable preferred direction occurs. A change in the performance of the Explosive charges are not planned.
  • the invention is therefore based on the object of a simple and Functionally reliable method of setting the target depending on the target Propose the performance of the warhead's explosive charge.
  • the form of the ignition device for a warhead With the form of the ignition device for a warhead according to the invention the following advantages are achieved.
  • By arranging another Ignition chain to the anyway for the detonative triggering of the explosive charge necessary ignition chain is also simple and inexpensive the deflagrative initiation of the explosive charge possible. Both lie down Ignition chains with respect to the longitudinal axis of the explosive charge, so is by means of a suitable choice of the two ignition times, even any one Setting the deflagrating portion of the explosive charge between 0 and 100% achievable.
  • FIG. 1 An explosive charge 1 of a warhead is shown in FIG a housing 6 is arranged.
  • the housing 6 can in a known manner the properties of the warhead can be adapted. This design has no significant influence on the function of the here present invention.
  • the explosive charge 1 consists of a homogeneous Explosive mass that completely fills the housing 6 over the length L. and which is needed to initiate a high energy level (stimulus). In the 1 shown boundary line 7 between the left and the right Half of the explosive 1 is explained below with reference to FIG. 2.
  • An ignition chain 2 is known on the right end face of the housing 6 Design attached.
  • three-stage ignition chains which consists of an electrically ignitable detonator, a transformer charge and an amplifier charge exist.
  • the booster charge 3 is referred to here, the immediate acts on the explosive charge 1. So far, with the help of the ignition chain 2 after recording a target and generating a corresponding one Ignition signal by means of a known ignition and safety device (not shown) the detonative triggering of the entire explosive charge 1.
  • the opposite ignition side of the housing 6 a further ignition chain 4 arranged.
  • This further ignition chain 4 has an amplifier charge 5 deflagration triggering device.
  • One possible execution is for example a shaped charge.
  • the further one Amplifier charge 5 dimensioned so that it is only one for the deflagration of the Explosive charge 1 can generate sufficient energy levels.
  • the one from the further stimulus charge 5 generated stimulus is significantly below that of the booster charge 3.
  • FIG. 3 is a diagram of the Reaction R of an explosive depending on the level of the stimulus ST, which is introduced by the booster charge.
  • a little Stimulus ST up to the first dashed vertical line of the Deflagration threshold does not react with explosives.
  • a Increase the ST stimulus to values between the two dashed lines vertical lines of the deflagration threshold and the detonation threshold triggers deflagration in the explosives. That means using the explosives a reaction speed of about 2000 m / s burns without one to produce a detonative blast effect. If the ST stimulus over the Detonation threshold increased, so the detonation of the Explosives with a reaction speed of about 8000 m / s.
  • the further amplifier charge 5 shown in FIG. 1 is exemplary as Hollow charge executed.
  • the vertical dashed line 7 represents the boundary between the explosive component 1 a to be detonated and the deflagrative component 1 b.
  • the speed of initiation during the detonation is about four times as high is like the rate at which the deflagration burns off, when the warhead approaches a target, the ignition chain 4 which triggers the deflagration must first be started.
  • the ignition chain 2, which triggers the detonation is initiated only after a delay time ⁇ t.
  • the time difference ⁇ t is characterized by the difference between the transit times t V of the deflagration front to the boundary line 7 and the transit time t D of the detonation front to the boundary line 7.
  • the ignition chain 2 must be triggered with a delay compared to the further ignition chain 5 by this time difference ⁇ t in order to achieve a reduction in the warhead output by 60%.
  • the missile carrying the warhead flies only a few centimeters, so that the time of detonation, which is determined with the aid of the ignition sensor system integrated in the missile, is not significantly affected.
  • the value of the power delivered by the explosive charge should be continuous between 0% and 100%, the Detonation can also be initiated before deflagration. It can be in in each case depending on the percentage of the desired effect determine certain delay time At, with which the detonation after the Deflagration is initiated or vice versa.
  • the solution according to the invention also allows the retrofitting of existing ones Warheads with an ignition chain 5 to initiate deflagration. If the structure and the spatial accessibility allow such a Retrofit device to any existing warhead Explosive charge to be grown. The existing ignition system is then over extended a second ignition output, whose ignition signal compared to the Ignition signal for the detonation trigger is delayed accordingly.
