Definitions

  • the present invention relates to an ammunition body according to the preamble of claim 1.
  • Two tier warheads also called tandem warheads, are among others against relatively thin armor and cells with sensitive content, such as helicopters, Airplanes and ships used.
  • Preloading is one of the so-called projectile-forming charges (English self-forging fragments) and has the task to punch or drill a hole as large as possible at the finish.
  • a warhead with a tandem charge includes known from EP -A1- 0 583 642, which is integrated in a karooka, to fight an enemy in their cover serves.
  • the protective wall or barricade for example is shot through with a shaped charge; with an additional charge Splinters are generated behind the cover.
  • the ignition on the cover takes place via piezo igniter hard targets and soft targets using proximity detonators.
  • the additional charge must always be delayed be initiated in order to not to endanger the shooter.
  • This warhead has the disadvantage that the second charge, or margin charge, called a relative must have small caliber to reach the target area to be able to penetrate. Accordingly, it can only be a limited one Create effect in the actual target. Likewise is an application-dependent due to the relatively small active body Time delay necessary so that this is possible close to the actual, to be destroyed or to be disturbed Target is fired.
  • Such warheads are therefore unsuitable for targets with redundant devices such as helicopters or ships, since either their limited effect by a Replacement system compensated and / or by an internal partition is additionally reduced or even eliminated.
  • Shaped charges are also known (US -A- 2 809 585) where those behind the lining of the cone-shaped summons Inert bodies are arranged, on the one hand, the detonation wave steer and on the other hand prevent the Reload resp. the downstream projectile through the Detonation front of the subpoena is adversely affected.
  • This well-known charge also reveals the features according to the preamble of procedural claim 10.
  • the Object provides improved system security, he but can only be used for the depicted, relative to the subpoena small reloads can be used. This is also here borehole achieved by the preload is only about the usual 0.4 times the caliber of the summons.
  • Another shaped charge with one or more cones protruding linings is from US -A- 5,663,475 known.
  • This shaped charge is primarily for applications in oil exploration and production. Doing so the explosive charge and the shaped charge in one massive guide anvil, which serves to direct the beam. This arrangement results in holes below the caliber size in the target and tends due to the outer beam path big losses, which negatively affects the depth of penetration of the annular beam.
  • a spherical lining characterized by three radii is described in US-A-5 320 044. Through this Lining should have two beams, one leading and one trailing ray are generated to penetrate deeper to achieve in the goal. The necessary acceleration the lining is made by an oversized, in your Diameter of this large-caliber one that is several times superior Explosive charge. The hole that can be reached at the target is consequently only a fraction of the caliber of the explosive charge.
  • the ammunition is said to fight transport or combat helicopters or in torpedoes against under or Above-water targets can be used. That by the subpoena
  • the opening created in the goal should be the way for a big one Expose the active charge and do not hinder it.
  • the subject of the invention is also intended in the civilian field be usable, especially in places that are difficult to access, where conventional drilling methods are limited due to Not enough space or only with a large amount of material and time expenditure are applicable.
  • the configuration of the subpoena according to the invention results the surprising effect that it created Borehole is actually larger than the caliber of the summons yourself and without the breakthrough performance (Drilling depth) significant compared to conventional cutting loads is reduced. This allows one or more Active charges, which are high Explosive or other to combat the specific Have effective properties.
  • the lining as such is characterized by its ignited charge to a stable floor in the form of a fragmented, strongly widened ring, which due to its size over any components in front, such as sensors and / or electronics fly away and their function not ended prematurely.
  • the projecting lining also called insert, is in the Contrasted with the knowledge in the specialist literature; the basic literature on shaped charges assumes this from that a liner in its axial area concave, i.e. except conical or bell-shaped, designed must be.
  • the lining according to the invention consists of those for this known ductile materials such as aluminum, iron, Electrolytic copper, lead, or tantalum and punches in the target an over-caliber disc through which one or more large effective loads without problems, i.e. without high kinetic Losses can penetrate deeply.
  • distance igniter used in claim 10 means every form of proximity fuse, whereby in In the simplest case, a double hood with internal contacting triggers the detonator on impact with the target. at stationary applications, for example in civil areas, this means an ignition at stand-off from at least one caliber to the target or to be drilled out Area.
  • a lining formed with the features of claim 1 acts as highly accelerated when hitting the target Cutting ring, the large-area fragments of which turn to the ideal orthogonal position on their flight and break through this with great energy.
  • a circular cutout With a completely different from the Environment separated inner pane.
  • the resulting differential acceleration of the Cutting ring is only minimally sensitive to an oblique Impact angle and results even at large distances the goal is a high penetration performance.
  • the subject of the invention relates to military applications especially on tandem or multiple warheads.
  • the ammunition body according to claim 2 results in a cheap Beam formation, so that a widened cutting ring is created.
  • a lining according to claim 3 in a spherical is favorable Dimensional shape.
  • the method of claim 10 leads to an optimal Use of the ammunition body according to the invention and leaves Adjustments to specific targets to be combated. For example in which the opening created by the subpoena fully used by the subsequent active charges or all loads on top of each other, on the armor and. be coordinated with the required depth effect in the target.
  • the one known per se has a particularly positive effect on the combat value delayed ignition of the active charge as this due to the large opening with high opening created by the summons kinetic energy, can penetrate far into the target.
  • the caliber of the active charge can be easily and without limitation, in full diameter.
  • the ammunition body is preferred in the sense of claim 11 used.
  • Fig. 1 is a projectile with a tandem warhead designated.
  • This floor 1 has a known one Double hood 2, which when they hit the target galvanically connects an ignition circuit, i.e. closes.
  • a preload 8 has a specially shaped lining 3 on, which can be accelerated by a snug charge 4 is. Behind is in a space 11 in Ammunition body 1 is a commercially available first ignition system 6 placed. This is followed by an active charge 7 which a high gas pressure effect is optimized and in its matrix Has stored fragments. The active charge 7 shows the full The caliber of the bullet opens and ends in a conical Rejuvenation 5.
  • the active charge 7 is ignited by a second ignition system 9, whose delay time is programmable depending on the target.
  • a solid-state engine 10 serves as the drive Design type. Leave hinged vanes 13 with rollers 14 centered in a launch tube, not shown insert; the corresponding axes of rotation are designated 15. A circular protection is used to protect the pipe Baffle plate 16, which after the ignition of the engine 10 is expelled.
  • the subsequent real charge 7 can thus be unimpeded penetrate their full caliber to the finish and even with slight inherent bulkheads due to their inherent kinetic energy penetrate and ignited there delayed, a high pressure and Develop a splintering effect.
  • Characteristic delay times between initiation the summons and a subsequent real charge depending on the speed of the engine 2.0 ms up to 10 ms.
  • the schematically shown precharge 8, Fig. 2 is also rotationally symmetrical and shows on its front F a spherical lining 3a made of aluminum. Their shape can be described as an annular bowl shape.
  • the explosives are initiated in a notoriously known manner Way through an igniter 6 with a downstream, also known inert body 17 (English wave shaper) for Direction of the detonation front in the axial area m.
  • the clamping point of the lining is in FIGS. 2 to Fig. 7 designated p and corresponds to its peripheral Border area.
  • the lining 3b in FIG. 3 formed from flat surfaces and exists in this variant made of an alloy of lead with 12% tin. Is also the lining 3b projecting in the axial area the neighboring coaxial area n.
