Definitions

  • the invention deals with a pyrotechnic active charge or active mass in a projectile, particularly in the medium caliber range, such as in the DE3240310 A described.
  • 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-T Pen bullets.
  • HE ammunition is also known that achieves fragmentation acceleration through the detonative conversion of secondary explosives.
  • the lateral acceleration caused by the PELE effect is essentially determined by the target speed.
  • the splitter cone becomes smaller. In practice, this represents a weakening of the effectiveness of the bullet on the target.
  • HE High Explosive
  • explosives are used, which increase the safety risk of such a projectile throughout its life cycle.
  • separate igniter components are required.
  • Multi-Purpose (MP) ammunition has the same problems as HE ammunition, even if classic fuse chains are not used here. However, the problem of undefined conditions arises, such as unexploded ordnance or implementation in the weapon due to feeding problems.
  • HE and MP bullets generally contain secondary explosives that are initiated by a pyrotechnic device (MP) or a separate detonator (HE).
  • MP pyrotechnic device
  • HE separate detonator
  • the EP 0 531 697 B1 discloses a multi-purpose projectile having a jacket, a penetrator and at least one incendiary charge. The incendiary charge is pressed in over its entire cross section.
  • the invention's task here is to provide a projectile that overcomes the aforementioned disadvantages.
  • the invention is based on the idea of developing a projectile which, without explosives or detonators, achieves a significant increase in the lateral fragmentation effect compared to a PELE projectile.
  • the aim is to combine a pyrotechnic active charge in combination with the proven PELE effect in a particularly medium-caliber bullet.
  • Non-explosive bullets are from the DE 10 2012 023 700 A1 as well as DE 10 2013 002 119 A1 known.
  • the explosive-free bullet according to the DE 10 2012 023 700 A1 releases a fuel or a fuel mixture as a flammable air-fuel mixture during decomposition at the target. This mixture is spontaneously implemented by at least one explosive-free, spark-generating ignition mechanism triggered during impact decomposition. These explosive-free bullets are used to create an optical and thermal target signature.
  • a non-detonable pyrotechnic set is integrated as the active mass.
  • a metal powder/oxidizing agent is preferably provided as the pyrotechnic composition.
  • the shock wave When impacting the target, the shock wave has a fragment-forming effect and at the same time initiates the active mass, so that the expanding gases from the pyrotechnics move the surrounding jacket fragments of the projectile body additionally laterally and from the Shooting distance and thus acceleration independent of the impact speed.
  • the redox reaction is used here, in which the chemical reaction of the pyrotechnic charge leads to a sudden exothermic redox reaction in which gas is released, expands greatly due to the temperature and thus creates the explosive force.
  • the pyrotechnic active mass can also create a flash and bang effect on the target or acoustically improve perception. In addition to marking the point of impact, this can hold the opponent down.
  • the multi-purpose bullet created in this way fulfills the task of armor performance, i.e. the bullet can penetrate armor, form splinters and also produce pyrotechnic effects such as incendiary, blast, lightning and/or bang effects on the target.
  • the pyrotechnic active mass is introduced into a projectile body of the projectile. It can be fixed in position using a disc, an epoxy resin or the like. Alternatively, the pyrotechnic active mass can be introduced into a projectile tip of the projectile.
  • a second embodiment results when a core is inserted into the projectile. This can then fix the pyrotechnic active mass in position.
  • the core material may have a lower density than the bullet body, but this is not a requirement.
  • a metal or plastic can be used as preferred.
  • the pyrotechnic active mass can be located between a projectile body and a penetrator.
  • the active mass can be enclosed and sealed by a core, which preferably also consists of a metal or a plastic.
  • the pyrotechnic active mass is attached in a ring around the penetrator.
  • the projectile body enveloping the pyrotechnic active mass forms the desired splinters after the active mass has been initiated.
  • a bullet with a new active mass or active charge in a bullet body preferably in the medium caliber range.
  • a shock wave is generated, which leads to the formation of splinters or fragments of at least the bullet body.
  • the pyrotechnic active mass is initiated by the introduced shock wave, so that the pyrotechnic active mass is converted and the expanding gases of the pyrotechnic active mass additionally accelerate the jacket fragments of the projectile body surrounding them.
  • the active mass is not converted detonatively, so they belong to a different class of substances than conventional explosives. This makes disposing of the ammunition less time-consuming. In addition, the handling safety of such ammunition increases.
  • the lateral effect is increased compared to pure PELE bullets. In addition, there is no secondary sentence. The lateral effect of the PELE ammunition is increased and leads to a less severe drop at long firing distances.
  • a projectile 1 comprises a projectile body 2, which has a projectile tip 3, also called an ogive or hood, at the front and a projectile tail 4 at the rear.
  • a pyrotechnic active mass 5 is introduced into the projectile body 2. This can be fixed in position using a disk, an epoxy resin 16 or the like. Alternatively, the pyrotechnic active mass 5 can be integrated into the tip of the projectile 3.
  • a bullet according to the invention shows Fig. 2 .
  • the pyrotechnic active mass 5 is integrated between a core 6 and a projectile body 7 of a projectile 8.
  • the core 6 preferably consists of a metal or a plastic.
  • the Fig. 3 shows a projectile 9 according to the invention with a projectile body 10 and a penetrator 11.
  • the projectile body 10 also has a projectile tip 3 on the front side and a projectile corner 4 on the rear side.
  • the penetrator 11 may itself be fragile.
  • the pyrotechnic active mass 5 is integrated between the projectile body 10 and the penetrator 11.
  • the pyrotechnic active mass 5 is preferably attached in a ring shape around the penetrator 11.
  • the active mass 5 can 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 preferably has a bore 15 into which the penetrator 11 can protrude. This bore 15 is preferably matched to the external geometry of the penetrator 11.
  • the core 14 itself preferably consists of a metal or a plastic. The core 14 allows the penetrator 11 to be fixed in position in the projectile 9 or in the projectile body 10. Alternative storage options for fixing the penetrator 11 are also possible.
  • Projectile bodies 2, 7, 10 and projectile tip 4 can be connected to one another via a screw connection.
  • the shock wave has a splintering effect on the jacket of the projectile body 2, 7, 10 (not shown in detail). Furthermore, this shock wave simultaneously initiates the pyrotechnic set 5 or the pyrotechnic active mass 5 through adiabatic compression. This causes the reaction temperature or reaction threshold of the redox system, i.e. the active mass 5 (pyrotechnics), to be exceeded. The active mass 5 reacts immediately. The now expanding gases of the pyrotechnic active mass 5 in turn additionally accelerate laterally the jacket fragments of the projectile body 2, 7, 10 which surround the active mass 5 and are formed by the shock wave upon impact.
  • the active mass 5 can also be several pyrotechnic sets that produce a fire effect, a lightning and/or bang effect at the target.
  • the advantage is that the fragment cone that forms (opening angle of the cone) of the casing fragments of the projectile body 2, 7, 10 is constant, since this is independent of the firing distance (the impact speed).
  • the projectile body 2, 7, 10 can also be provided with predetermined breaking points (not shown in detail) on the circumference. These can then support the formation of splinters on projectiles 1, 8, 9.
  • the size of the casing fragments of the projectile body 2, 7, 10 can also be better defined by the predetermined breaking points.
