Definitions

  • the invention relates to a compressible fire mass, with a metallic fuel of group IVA of the periodic system and an organic binder.
  • the metals used are preferably titanium and zircon.
  • the preferred binder is polyvinyl acetate.
  • this fire mass is preferably arranged in a projectile or warhead together with an explosive explosive. But it can also be pressed into the cavity of a projectile that does not contain explosives, e.g. B. armor-piercing projectiles without explosives.
  • the detonative or mechanical fragmentation of the projectile or warhead in or near the target creates not only the splinters, but also rapidly flying fire mass particles that burn autonomously in the air. This creates a fire effect that is extensive in terms of space and time.
  • a known fire mass of this type contains an organic binder and a metal sponge z.
  • Known sliver fire ammunition contains mixtures of highly explosive explosives such as hexogen, octogen, trotyl and aluminum powder.
  • highly explosive explosives such as hexogen, octogen, trotyl and aluminum powder.
  • the addition of metal increases the blowing effect and extends the flame burning time from 1 ms to 15 ms. This increases the likelihood of ignition for combustible material in the target - e.g. B. leaking fuel - enlarged.
  • fluorinated binders is said to aid combustion by forming the tetrafluoride of the corresponding metal.
  • metals in the form of coarse-grained, porous, sponge-like particles with a particle size of 0.05-8 mm the aim is to extend the burning time.
  • the use of a metal sponge is not absolutely necessary and that too much binder has an unfavorable influence on the effect of the combustible metal particles, in particular on the burning time and the flight distance.
  • the binder must therefore be used in the lowest possible concentration, which still ensures that the metal powder can be pressed sufficiently.
  • the proportion of the binder in the fire mass is therefore less than 2% by mass.
  • the binder can be mixed in the usual way as a lacquer solution with the metal powder. By sieving and removing the solvent at elevated temperature, a compressible granulate is created.
  • halogen-containing binders do not effectively support the combustion of the metals. This can also be derived from the volume and mass-specific reaction enthalpies.
  • the metal fluorides formed are volatile and withdraw energy from the system when they evaporate.
  • the organic binder used according to the invention is therefore halogen-free.
  • the metal sponges used for the production of fire masses can be replaced by metal powder of pyrotechnic quality without significant loss of burning time.
  • the advantage is a strong reduction in the risk of explosion when the fire mass is compressed with the explosive.
  • the risk of explosion is high when using relatively large, sponge-like particles with a hard, jagged surface.
  • metal powder with an average grain size of 15-50 f.Lm is therefore used.
  • projectile bodies were statically blasted with 5 g of fire mass pressed in on the face and 25 g of a highly explosive explosive consisting of hexogen and trinitrotoluene.
  • the projectile body was placed vertically on a solid surface.
  • the charge was detonated using an electrically triggered ignition system.
  • the flight distance and burning time of the flinging, cone-shaped, burning metal particles were measured.
  • Binder 1% by mass of polyvinyl acetate
