Definitions

  • the invention relates to a warhead according to the preamble of claim 1.
  • Warheads with a splinter effect are often used to combat semi-hard targets or very fast targets. This means that either the effect of multiple hits is improved or that the probability of a hit is increased.
  • splinter generation was previously carried out by accelerating preformed splinters, which e.g. were arranged in a few, relatively thin layers in the warhead. As a result, it is hardly possible to concentrate a large number of fragments on a defined solid angle.
  • AT-B 367 902 describes a clearing load for creating an alley in minefields. It creates a bundled splinter beam.
  • the front end of the clearing charge is concave and provided with a splinter filling made of prefabricated chips.
  • the fragments are embedded with gaps in the explosive.
  • the disadvantage of detonating the clearing charge is that the detonation pressure is only transmitted to a small extent to the individual fragments. The gaps through which a large part of the detonation pressure escapes are decisive. The range of the splinter beam is therefore short.
  • a disadvantage is that the splinter jet is not or only incompletely formed if the splinters are distributed unevenly.
  • the object of the invention is to propose a warhead which has a long-range splinter beam.
  • the simple and inexpensive warhead is advantageous. With the usual central ignition, a concentrated fragment cone of highly effective fragments is generated in a defined solid angle, which, with the appropriate warhead dimensions, penetrates the base plate of a titanium-aluminum helicopter or the armor of an armored personnel carrier at a distance of 100 m.
  • the mass of a splinter is 5 g on average.
  • the total splinter mass is approximately 1.2 to 1.3 kg.
  • the invention is therefore also suitable for down-to-earth mines for combating helicopters and / or airplanes in the deepest flight up to approximately 100 m above ground.
  • the material from which the covering is made is essential to the invention.
  • This material must have a low elongation at break at high strain rates, i.e. it must be brittle at strain rates of the order of 1000 m / s and more.
  • a high ductility of the material at low expansion speeds, as is usual for non-cutting forming processes, is advantageous. In previous applications, materials with a static elongation at break between 15 and 25% were used.
  • a high specific density of the covering material is advantageous for the breakdown performance of the generated fragments. It is known from theory that the penetration performance of a penetrator is a first approximation is proportional to the square root of the penetrator density.
  • a warhead 1 has a housing 2, an ignition 3, explosives 30 and an assignment 4.
  • the assignment 4 is formed into a splinter cone 10 with a cone angle 11 of 2 ° .
  • the fragment cone 10 has fragments with an average fragment mass of 5 g.
  • the thickness of the assignment 4 is designated 5 and the radius of curvature 6.
  • the data mentioned are modified in order to achieve a wide horizontal fragmentation beam in the form of a fragment wedge with a wedge angle of approximately 2 ° .
