Definitions

  • the present invention relates to an ammunition body with a multi-stage rotationally symmetrical warhead, with at least one precharge and a distance detonator, at least the precharge having a shaped charge.
  • Two-stage warheads also called tandem warheads, are used against relatively thin armor and cells with sensitive contents, such as helicopters, airplanes and ships.
  • the preload used here belongs to the so-called projectile-forming charges (English self-forging fragments) and has the task of punching or drilling a hole as large as possible.
  • EP-A1-0 583 642 a warhead with a tandem charge is known (EP-A1-0 583 642), which, integrated in a bolooka, fights the enemy in cover, i.e. shoots through the protective wall or barricade with a shaped charge and generates splinters with an additional charge behind the cover.
  • the ignition at the cover takes place via piezo igniter for hard targets and for soft targets with proximity igniter; the additional charge is initiated with a time delay.
  • warheads have the disadvantage that the second charge or additional charge must have a relatively small caliber in order to be able to penetrate the target area. Accordingly, it can produce a limited effect on the actual target. Likewise Due to the relatively small active body, a time delay is necessary so that it is ignited as close as possible to the actual target that is to be destroyed or disrupted.
  • warheads are therefore not suitable for targets with redundant devices such as helicopters or ships, since either their limited effect is compensated for by a replacement system or additionally reduced or eliminated by internal partitioning.
  • the opening in the finish created by the summons should open the way for the large active cargo and not hinder it.
  • the design of the precharge according to the invention results in the surprising effect that the borehole produced by it is larger than the caliber of the precharge itself.
  • one or more active charges can be connected which have a high explosive effect or other properties which are effective to combat the specific target.
  • the lining becomes a stable projectile in the form of a fragmented, greatly expanded ring which, due to its size, flies over any components such as sensors and / or electronics arranged in front of it and therefore does not prematurely terminate its function.
  • the protruding lining also called insert, is shaped in stark contrast to the knowledge in the specialist literature; the literature assumes that a lining is concave in its axial area, i.e. except conical or bell-shaped, must be designed.
  • the lining itself consists of the ductile materials known per se, such as aluminum, iron, electrolytic copper, lead, or tantalum, and punches out an over-calibrated disc in the target, through which one or more large active charges can be easily, i.e. can penetrate deeply without high kinetic losses.
  • distance detonator used in the claim means any form of proximity detonator, in the simplest case a double hood with internal contacting triggers the detonator when it hits the target.
  • the ammunition body according to claim 2 results in a favorable jet formation, so that a widened cutting ring is formed.
  • a lining according to claim 3 in a spherical spatial shape is favorable.
  • the effect of the detonation wave on the lining can be further optimized.
  • the method according to claim 11 leads to an optimal use of the ammunition body according to the invention and permits adaptations to specific targets to be combated. For example, in which the opening created by the preload is fully used by the subsequent active charges or all charges are matched to one another, to the armor and to the required depth effect in the target.
  • the delayed ignition of the active charge which is known per se, has a particular effect on increasing the combat value, since it can penetrate far into the target through the large opening with high kinetic energy generated by the precharge.
  • the caliber of the active charge can be used without problems and without restrictions, in full diameter.
  • the ammunition body is preferably used in the sense of claim 12.
  • Fig. 1 is a shaped charge with a tandem warhead.
  • This projectile 1 has a double hood 2 known per se, which galvanically connects an ignition circuit when it hits the target, i.e. closes.
  • a preload 5 has a specially shaped lining 3, which can be accelerated by a snug charge 4.
  • a commercially available first ignition system 6 is placed in an intermediate space 11 in the ammunition body 8.
  • the active charge 7 has the full caliber of the projectile.
  • the active charge 7 is ignited by a second ignition system 9, the delay time of which can be programmed depending on the target.
  • a solid-state engine 10 serves as the drive.
  • Hinged guide vanes 13 with castors 14 can be inserted centrally into a launch tube, not shown; the corresponding axes of rotation are designated 15.
  • a circular baffle plate 16 serves to protect the tube and is ejected after the engine 10 is ignited.
  • the guide vanes 13 show up in the form of a radial tail assembly 12, as indicated in the drawing.
  • This tail unit 12 prevents rotation ("spin") of the ammunition body 1 and thereby ensures an optimal cutting action of the shaped charge in the target, a hole 1.5 times the diameter of the caliber being punched out of a steel plate with a thickness of 0.15 caliber.
  • the inner disk accelerated in the direction of flight results in a diameter of 1.0 times the caliber.
  • the subsequent active charge 7 can thus penetrate the target unhindered with its full caliber and even penetrate light bulkheads with its inherent kinetic energy and, when delayed, can develop a high pressure and splintering effect.
  • Characteristic delay times between the initiation of the pre-charge and a subsequent active charge are 2.0 ms to 10 ms, depending on the speed of the engine.
  • the schematically illustrated ammunition body 8, FIG. 2 is likewise rotationally symmetrical and has a spherical lining 3a made of aluminum on its front side F. Their shape can be described as an annular bowl shape.
  • the initiation of the explosive takes place in a notoriously known manner by an igniter 6 with a downstream, also known inert body 17 (English wave shaper) for directing the detonation front into the axial area m.
  • the lining 3b in FIG. 3 is formed from flat surfaces and in this variant consists of an alloy of lead with 12% tin.
  • the lining 3b is also projecting in the axial area relative to the adjacent coaxial area n.
  • the ignition 6 is followed by an ignition amplifier 6 '.
  • FIG. 4 the schematically represented ammunition bodies 8 are typified, namely the variant in FIG. 4 is designated A and is representative of linings 3c thickened in the axial region m.
  • Variants B, FIGS. 5 to 7 relate to linings 3d with a uniform wall thickness; Linings 3e with peripherally increasing wall thickness and thinner linings 3f in the axial region.
  • initiation of the charge 4 is assumed to be 2.5 to 3.0 times the caliber of the charge.
  • the fragments 3c 'to 3f' punch out an annular space 21 with an outer diameter of 2.2 times the caliber and an inner diameter which corresponds approximately to the caliber.
  • the resulting disc 22 is completely punched out.
  • the subject matter of the invention can be adapted to numerous weapon systems but also to civil applications by suitable adaptations.
  • Torpedoes are conceivable that use the over-caliber opening, for example in a ship's hull, for introducing multiple stages of active charges.
  • Components such as sensors and / or control electronics could also be arranged in the head of the projectile in new weapon systems, without these being damaged by the precharge itself and falling prematurely out of operation. - The effectiveness of the summons is not disturbed by such an arrangement; the length of the ammunition could be better used and the overall ballistics improved.
  • burst openings can be implemented, which have to be carried out on highly loaded containers in the event of emergency shutdowns. Rapid flooding of tightly closed rooms, for example in the event of a fire, is also possible, but also pressure relief is possible without the need for special installations of costly closures and / or drive means.
