Definitions

  • the invention is concerned with a pyrotechnic active charge or effective mass in a projectile, in particular in the middle caliber range.
  • EP 1 316 774 B1 EP 1 000 311 B1 describe the so-called PELE effect, which is used in so-called PELE-T or PELE-pen projectiles. Furthermore, HE ammunitions are known which achieve splinter acceleration via a detonative conversion of secondary explosives.
  • the lateral acceleration due to the PELE effect is essentially determined by the target speed.
  • the splinter cone becomes smaller. In practice, this represents a weakening of the effectiveness of the projectile in the target.
  • HE High Explosive
  • blasting grenades The splinter acceleration when using HE (High Explosive) bullets or ammunition, such as blasting grenades, is known to be very good.
  • explosives are used which increase the safety risk of such a bullet throughout its life cycle.
  • separate detonator components are needed.
  • Multi-Purpose (MP) ammunition has the same problem as HE ammunition, though it does not use classic detonating chains. However, the problem of undefined states, such as duds or implementations in the weapon in feeding problems.
  • HE and MP projectiles generally contain secondary explosives that are initiated by a pyrotechnic set (MP) or a separate igniter (HE).
  • EP 0 531 697 B1 discloses a multi-purpose projectile which has a jacket, a penetrator and at least one fire charge.
  • the fire charge is in this case pressed over its entire cross section.
  • the invention has the object to show a bullet, which overcomes the aforementioned disadvantages.
  • the invention is based on the idea to show a projectile, which, without explosives and detonators, realizes a significant increase in the lateral fragmentation effect in relation to a PELE projectile.
  • the aim is to combine a pyrotechnic active charge in combination with the proven PELE effect in an especially medium-caliber projectile
  • Explosion-free projectiles are known from DE 10 2012 023 700 A1 and DE 10 2013 002 119 A1
  • the explosive-free projectile according to DE 10 2012 023 700 A1 releases a fuel or a fuel mixture as an inflammable air-fuel mixture during the disassembly into the target. This mixture is spontaneously reacted by at least one explosive-free, spark-generating ignition mechanism triggered during the breakdown decomposition.
  • These explosive-free projectiles serve to create an optical and thermal target signature.
  • a non-detonation-capable pyrotechnic composition is incorporated as active compound.
  • a metal powder / oxidizing agent is preferably provided.
  • the shock wave splinters and simultaneously initiates the active mass, so that the expanding gases of pyrotechnics, the surrounding shell fragments of the projectile body laterally and from the Firing distance and thus accelerate independently of the impact speed.
  • the redox reaction is utilized, in which a sudden exothermic redox reaction occurs due to the chemical reaction of the pyrotechnic composition, in which gas is released, greatly expands due to temperature and thus causes the explosive force
  • the pyrotechnic active mass can also create a lightning and bang effect on the target or acoustically improve the perception. In addition to the marking of the impact point of the opponent can be held down.
  • the thus created Mer mixturegeunter fulfills the task of a tank performance, i.
  • the projectile can penetrate an armor, form splinters and also pyrotechnic effects, such as fire, biast, lightning and / or bang effects in the target form.
  • the pyrotechnic active mass is introduced into a projectile body of the projectile. It can be fixed in position by a disk, an epoxy resin or the like. Alternatively, the pyrotechnic active mass may be introduced into a projectile tip of the projectile.
  • a second embodiment results when a core is introduced into the projectile. This can then fix the position pyrotechnic active mass.
  • the material of the core may have a lower density than the projectile body, but this is not a condition.
  • the pyrotechnic active mass may be located between a projectile body and a penetrator.
  • the active material can be enclosed and sealed by a core, which preferably also consists of a metal or a plastic.
  • the pyrotechnic active mass is attached annularly around the penetrator. The bullet body enveloping the pyrotechnic active mass forms the desired splinters after initiation of the active mass
  • a projectile with a new active mass or active charge in a projectile body preferably in the middle caliber range.
  • a shock wave is generated, which leads to splitting or fragmentation of at least the projectile body.
  • the initiation of the pyrotechnic active mass is effected by the initiated shock wave, so that the pyrotechnic active material is reacted and the expanding gases of the pyrotechnic active mass additionally accelerate the surrounding shell fragments of the projectile body.
  • the active material is not reacted detonatively, so they belong to a different class of substance than conventional explosives. Disposal of the ammunition is therefore less expensive.
  • the handling safety of such ammunition increases.
  • the lateral effect is increased compared to pure PELE bullets.
  • a secondary rate is waived.
  • the lateral effect of the PELE ammunition is increased and leads to a less severe decrease in long shooting distances.
  • FIG. 1 shows a first variant of a projectile according to the invention
  • Fig. 2 shows another variant of the projectile
  • Fig. 3 shows a third variant of the projectile.
  • a projectile 1 comprises a projectile body 2, which on the front side has a projectile nose 3, also called an ogive or hood, and has a projectile tail 4 on the rear side.
  • a projectile body 2 In the projectile body 2 is introduced a pyrotechnic active mass 5. This can be fixed in position by a disc, an epoxy resin 16 or the like. Alternatively, the pyrotechnic active mass 5 can be integrated into the projectile nose 3.
  • FIG. 2 An alternative is shown in FIG. 2.
  • the pyrotechnic active mass 5 is incorporated between a core 6 and a projectile body 7 of a projectile 8.
  • the core 6 is preferably made of a metal or a plastic.
  • FIG. 3 shows a projectile 9 with a projectile body 10 and a penetrator 1 1.
  • the projectile body 10 also has a projectile nose 3 on the front side and a projectile cusp 4 on the rear side.
  • the penetrator 11 may in turn be fragile.
  • the pyrotechnic active mass 5 is incorporated between the projectile body 10 and the penetrator 11. In the preferred embodiment, the pyrotechnic active mass 5 is preferably attached in a ring around the penetrator 11.
  • the active mass 5 completely, but at least partially cover the penetrator 11.
  • the active mass 5 is enclosed by a core 14 and thereby sealed.
  • the core 14 sits at least partially on the penetrator 11.
  • the core 14 has a bore 15 into which the penetrator 11 can protrude.
  • This bore 15 is preferably matched to the outer geometry of the penetrator 11.
  • the core 14 itself preferably consists of a metal or a plastic.
  • the penetrator 11 can be fixed in position in the projectile 9 or in the projectile body 10. Alternatives of storage for fixing the penetrator 11 are also possible.
  • Projectile body 2, 7, 10 and projectile nose 4 can be connected to each other via a screw.
  • the well-known PEIE effect is triggered.
  • a shock wave is introduced into the projectile body 2, 7, 10 and, if present, also into the core 6 (FIG. 2) or into the core 14 and the penetrator 14 (FIG. 3).
  • the shock wave acts on the one hand on the jacket of the projectile body 2, 7, 10 fragment-forming (not shown in detail). Furthermore, the pyrotechnic composition 5 or the pyrotechnic active material 5 is simultaneously initiated by adiabatic compression by means of this shock wave. As a result, the reaction temperature or reaction threshold of the redox system, that is, the effective mass 5 (pyrotechnics), is exceeded. The active mass 5 reacts immediately. The now expanding gases of the pyrotechnic active mass 5 in turn accelerate the active mass 5 surrounded and formed by the Stoßwetie at impact coat fragments of the projectile body 2, 7, 10 in addition, laterally.
  • the active mass 5 may also be a plurality of pyrotechnic sows which produce a fire effect at the target, a lightning and I or bang effect. It is advantageous that the forming splitter cone (opening angle of the cone) of the shell fragments of the projectile body 2, 7, 10 is constant, since this is independent of the firing distance (the impact velocity).
  • the projectile body 2, 7, 10 may be circumferentially additionally provided with predetermined breaking points (not shown in detail). These can then support the fragmentation of the projectile 1, 8, 9. Also can be better defined by the predetermined breaking points, the shell fragments of the projectile body 2, 7, 10 in size.
