Definitions

  • the invention relates to a universal KE projectile according to the preamble of patent claim 1, a method for producing the projectile and its use.
  • EP 0 853 228 B1 discloses a generic projectile and a method for its production. With this method, bullets with one- or multi-part bullet bodies (penetrator or penetrator parts) of different shapes and sizes can be produced easily and in a time-saving manner.
  • the shell of the projectile consists of a projectile tip firmly connected to a projectile casing, which has a centering on the inside in which the projectile body is guided and held. The back of the projectile casing is closed with a sealing body which partially encompasses the projectile body.
  • the bullet shell and the bullet tail are often made of aluminum, with steel also being used.
  • the ballistic bullet tip is also made of aluminum, but can also be made of plastic.
  • FAP Frrangible Armor Piercing
  • a core made of frangible material, which according to EP 0 853 228 B1 can be composed of different frangible pills.
  • Frangible as well as ductile heavy metal is proposed as the material for these sub-storey structures.
  • the core is coated with plastic, for example, by injection molding.
  • the performance in the target depends on the impact speed.
  • the top of the floor or the floor Break open the shell so that the frangible core can work. Breaking open a fangible core also requires energy. At low impact speeds (e.g. long shooting distances) the energy is often too low so that the core is still sufficiently fragmented. As a result, the breadth of the target becomes smaller.
  • Such a core also has the property that it breaks into several splinters, for example for test purposes to simulate different targets in a relay target. These fragments continue to break onto the next plate, etc., which is called the cascade effect. These fragments can become so small that their energy is no longer sufficient to be able to penetrate the next plate. That is, after a few slabs (in greater target depth), the desired broad effect coincides.
  • FRAP Fraping Payload
  • cannon ammunition no longer has, among other things, an HE filling and no impact detonator.
  • More detailed information on FRAP ammunition and the pre-fragmented tungsten active substance can be found in the article "Fragmenting Payload Ammunition Frap" by Allan Buckley & Pierrre H. Freymond at NDIA 37th Gun & Ammo Syposium from April 15th to 18th, 2002 in Panama City was held (http://www.dtic.mil/ndia/2002gun/buckley.pdf).
  • the object of the invention is to increase the broad effect in a target.
  • the highest possible penetration rate should be achieved in a monoblock target.
  • the invention is based on the idea of combining the cascade effect of the frangible pills with sub-projectiles made of ductile heavy metal, i.e. to create an ammunition in which the advantages of a central penetrator consisting, for example, of frangible pills, are combined with the advantages of ductile heavy metals of an external penetrator.
  • Ductile heavy metal has the property of not breaking on the target plates, so that a good splinter cone can form.
  • a jacket penetrator for a KE projectile which protects the pressure-sensitive penetrator as a ductile casing and whose fireproof attachment to the penetrator core enables cost-effective series production.
  • the preferably arcuate outer penetrator, made up of individual subprojectiles should trigger the buckling effect here, so that the shell of the projectile around the outer penetrator immediately tears and releases the ductile subprojectiles become.
  • these subprojectiles are fixed with injected plastic in the external penetrator, which has the advantage that the shell of the projectile surrounding the external penetrator can be made very thin. This thin shell results in an easy opening in the target.
  • the central penetrator made of frangible pills mainly acts in a monoblock target. This enables this projectile to be used universally.
  • FIG. 2 shows a sectional illustration of the front part of the projectile from FIG. 1,
  • FIG. 3 shows a variant of a sectional illustration of the front part from FIG. 1.
  • FIG. 4 shows a further variant from FIG. 1.
  • an ammunition 10 which essentially comprises a projectile 1, a guide band 2, grooves 3, a cartridge case 4, propellant charge 5.
  • FIG. 2 shows a section of the projectile 1 for closer inspection, FIG. 2 including a first embodiment.
  • the projectile 1, a universal (multi-purpose) KE projectile, is formed by a projectile tip 20, a projectile envelope 21 and a projectile rear 22.
  • 24 denotes a central penetrator, which is preferably composed of frangible pills 25, but can also be made of one piece, and in many cases is also referred to as a projectile core.
  • An outer penetrator denoted by 26 consists of spherical 27, possibly also cylindrical 28 (cylinder-like or -like and / or cube-shaped and / or barrel-like) ductile heavy metals (FIG. 3), which are referred to here as sub-projectiles 27, 28.
  • An end penetrator 29, preferably the end of the frangible central penetrator 24, also has a further variant according to FIG. 4 spherical or cylindrical ductile heavy metals 30, which are also referred to as subprojectiles.
  • the outer penetrator 26 preferably has an arc-shaped or banana-shaped shape or arrangement in order to preferably trigger the kinking action, so that the projectile shell 21 tears and the sub-projectiles 27, 28 are released.
  • the ammunition 10 strikes a target, which is not shown in detail, in addition to the projectile tip 20, the projectile casing 21, supported by the external penetrator 26, is destroyed.
  • the released sub-projectiles 27, 28 in turn support the central penetrator 24 or the pills 25 when penetrating the target.
  • a further improvement can also be created by using the end penetrator 29.
  • the subprojectiles 30 also have a supporting effect here.
  • the projectile tip 20 and the projectile casing 21 can be made of aluminum. Alternatively, it is also possible to form the projectile tip 20 from injection-molded material, for example from plastic. This plastic can preferably be a high-temperature, fiber-reinforced, thermoplastic. The same applies to the projectile casing 21, which can also be formed from a plastic, a combination of plastic and steel also being offered here.
  • plastic is injected from the projectile tip 20, wherein the plastic can also be injected from the rear side.
  • This variant requires, for example, only a small hole, preferably centrally in the rear area.
  • the use of plastic enables the use of a very thin shell 21. The process involved is simple and enables inexpensive fabrication.

Abstract

L'invention vise à associer l'effet cascade des pastilles désintégrantes (25) avec des sous-projectiles (27, 28, 30) réalisés en métal lourd ductile, c'est-à-dire à créer une munition (10) qui allie l'avantage, par exemple, des pastilles désintégrantes (25) d'un pénétrateur central (24) aux avantages des métaux lourds ductiles (27, 28) d'un pénétrateur externe (26). Cela permet d'obtenir une puissance améliorée dans différents objectifs même pour des vitesses d'impact profondes. Le pénétrateur externe est réalisé en forme d'arc ou de banane.
