Definitions

  • the invention relates to a warhead according to the preamble of claim 1 and to a method for producing the warhead.
  • the lining consists of a particle composite material formed from tungsten and copper.
  • the individual tungsten grains are treated with a binder, e.g. Nickel or palladium, with which copper is brought together to form a homogeneous structure. Accordingly, a high density spike is achieved.
  • Warheads with a splinter effect are often used to combat semi-hard targets or very fast targets. This means that either the effect is improved by multiple hits or that the probability of hits is increased.
  • splinter generation has so far been achieved 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.
  • the object of the invention is to propose a warhead that generates high-energy splinters in the axial direction, which spread out in a defined solid angle.
  • 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 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 in a first approximation 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 coating 4 consists of a tungsten sintered alloy with 90% by weight tungsten 6.5 wt% nickel 3.5% by weight iron with an elongation of 25%.
  • 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.
  • Diameter of the assignment 4 100 mm
  • Weight of the explosive 30 2.4 kg
  • Weight of the assignment 4 1.37 kg
  • Radius of curvature 6 of Assignment 4 180 mm.
  • the data mentioned are modified in order to achieve a broad horizontal fragment beam in the form of a fragment wedge with a wedge angle of approximately 2 °.
