Definitions

  • the invention is directed to a warhead with a shaped charge and a detonator in a warhead housing and a spacer which can be extended in the flight direction from the warhead housing, the ignition of the shaped charge being triggered when the spacer tip hits the target.
  • a warhead with an extendable spacer is known from DE 3 727 652 C1 or DE 3 804 992 C1.
  • the spacer is extended by inertial forces generated during firing, the spacer tip is automatically brought into the furthest possible position in front of the shaped charge cone.
  • the shaped charge is ignited by a impact sensor (it can also be accommodated in the detonator and is then triggered by the shock wave passing through the spacer) at a time-determined interval.
  • a impact sensor it can also be accommodated in the detonator and is then triggered by the shock wave passing through the spacer
  • Such bullets can be used to create relatively narrow holes in very thick concrete walls or armor. If such a warhead is used to shoot against thinner armored objects or against bunkers and fortifications, the effect is relatively low because the shaped charge spike is designed for a large depth and does not have a wide effect.
  • Reactive armor has been developed, particularly because of the threat from shaped charge projectiles.
  • plates covered with explosives are attached to the outside of the object to be protected; the ignition of the explosive triggered by the projectile leads to the acceleration of the plates, which then considerably disrupt the formation of the shaped charge spike, so that even objects with thinner passive armor can be effectively protected against shaped charge spikes.
  • a floor must first clear away the explosive occupancy.
  • a warhead described in DE 3 804 992 C1 contains a pre-hollow charge (tandem warhead) in an extendable spacer; the pre-charge is ignited before the main charge.
  • the object of the invention is to provide a warhead with a shaped charge projectile which can be adjusted to the type of passive armor, i.e. H. on a uniform warhead, it should be possible to set whether either a very high penetration, limited to a relatively narrow channel, should be generated or whether a large hole should be shot in thinner armor or in masonry.
  • this adjustability should also be given for a tandem projectile which has a pre (hollow) charge before the (main) shaped charge, usually for triggering the explosive in reactive armor, and in which the width effect should also be able to be increased at the expense of the depth effect .
  • the task is solved by a warhead of the above-mentioned type in that, independently of other warhead functions, a partial or full extension of the spacer on the warhead or also the remaining of the spacer in front of the shaped charge is possible, and the spacer can be fixed in the respective fully or partially extended position is.
  • a pre-charge preferably a pre-hollow charge
  • the spacer (usually by hand immediately before the shot) also being able to be pulled out wholly or partly or not by the shooter and in the whole or in part even in such a warhead extended position on the warhead housing can be fixed.
  • the partial or full extension of the spacer can take place “automatically”, ie. H. the spacer can be moved, for example by firing a pyrotechnic force element, by means of a usually electrical signal when fired in connection with a control or delay device.
  • Such devices are prone to failure and mean additional weight and more effort. It is particularly favorable in the device according to the invention that the mechanical adjustability of the spacer and its locking by hand by the shooter is easily possible immediately before the shot.
  • the extension can be undone at any time without any problem.
  • a particularly preferred embodiment is characterized in that, in addition to the (main) shaped charge, an explosive device is installed in the spacer as a pre-charge, preferably a pre-shaped charge.
  • an explosive device is installed in the spacer as a pre-charge, preferably a pre-shaped charge.
  • a shaped charge 1 with an insert 2 in a housing 3 can be initiated by a detonator 4 which can be screwed into the floor.
  • the igniter 4 contains an electrical converter for generating an ignition voltage, a detonator and a booster.
  • the ignition voltage arises when a shock wave that occurs when the spacer tip 5 strikes the target enters the igniter 4 via the annular spacer 6 and the housing 3.
  • the ignition of the shaped charge 1 could also be initiated differently in a known manner, for example by a sensor which is installed in the spacer tip 5 and the signal from there is passed on to the igniter 4 via electrical cables.
  • the spacer 6 is dimensioned so that a hollow charge spike can form undisturbed in the free space 8 above the insert 2.
  • the spacer 6 should be lockable with a spacer tube guide 7, e.g. B. by a snap or a bayonet lock.
  • a spacer tube guide 7 e.g. B. by a snap or a bayonet lock.
  • intermediate positions of the spacer 6 will have to be dispensed with, i. H. the spacer tube should either be fully extended, so that as much space and time as possible is available for the formation of the shaped charge spike, or the spacer 6 is not pulled out at all (as in FIG. 1 or 3), so that the depth effect is poor, but with the "too" late "detonation of the explosive of shaped charge 1, a considerably stronger lateral effect can be achieved and thus man-sized holes can be torn open with less strong armor or in masonry.
  • FIGS. 3 and 4 show a tandem warhead with a pre-charge, here with a pre-hollow charge 10, as is known for example from DE 3 804 992 C2, with the spacer 6 retracted and fully extended.
  • the pre-charge 10 is ignited before the charge 1.
  • the warhead according to FIG. 4 is distinguished by a particularly high penetration rate with very massive passive armor, but only a relatively narrow penetration channel is formed. According to the invention, such a warhead has a very great effect with thinner armor, even with reactive pre-armor, if the spacer 6 is not or only partially extended (FIG. 3).
  • the ignition timing of the pre-charge and the main charge are determined according to the requirements of the respective warhead.
