Definitions

  • the invention relates to a propellant grain for a stratified propellant according to the preamble of claim 1.
  • a charge build-up is higher to increase the performance of existing barrel weapons Loading density required, see US-A 4,094,248 (basis for the preamble of claim 1).
  • Geometrically through arrangements shaped single grains with a hexagonal cross-section are higher loading densities than can be achieved with bulk powder.
  • the one on the outside of the hexagonal Grains and holes arranged inside the body have a very small cross-section so that the flame front gradually turns away from the kindled Front face spreads in the longitudinal direction.
  • the invention has for its object a propellant for a stratified Propose propellant charge with good kindling.
  • the invention solves this problem according to the characterizing features of claim 1.
  • the polygonal multi-hole grain according to the invention has at its corner points special longitudinal grooves, the radius of which is considerably larger than the radius of the hole Grains.
  • the longitudinal grooves With a stratified propellant charge with grains arranged side by side the longitudinal grooves each form flow channels with a circular cross section. The diameter of these channels ensures that the wall surface is lit. of the entire flow channels lying one behind the other, namely from the ignition side to the end of the grain, that is to say the end of the grain. Accordingly then a particularly good ignition and ignition of the grains is guaranteed, if the radius of the groove is 1.5 to 4 times the web width or after Claim 2 which is 10 to 20 times the hole radius.
  • the end faces of the grains with spacers like knobs connected in one piece with the grain.
  • a separate spacer such as a dimensionally stable, folded, combustible film is also the respective one Front ignition of the grains guaranteed.
  • triangular grains 2 of a propellant charge are in a propellant charge sleeve 1 10 covering the entire area with respect to the cross section of the propellant charge sleeve 1 each six-surface, (merging) surface segments 4 assembled and - corresponding to a charge length, not shown - on each other stacked.
  • Each grain 2 has at its corner 3 a longitudinal groove 5 with a radius 6 and thus a corresponding circular section 7 and through holes 9.
  • the radius 6 of the channels 20 is 1.5 times a web width 22 between two holes 9.
  • a grain 30 is provided with a square cross section and has at its corners 31 a longitudinal groove 33 with a 90 ° cutout 32 with the Radius 6 on.
  • a six-surface grain 40 has one at each of its corners 41 Longitudinal groove 43 with a 120 ° cutout 42 with radius 6 and the holes 9 on.
  • the spacer 61 is a multi-edged, separate film consists of propellant powder. This film 61 ensures the Distance 52.
  • the hot ignition gases include both channels 20 and subchannels 17-19 and the transverse channels 53. This is a - starting from the longitudinal grooves 5 and 32 respectively simultaneous burning of grains 2 and 30 achieved from the outside.
  • Front firing fronts on the grains 2, not shown, are known in the art Way supported by the holes 9. This is the required, good ignition property on grain 2 or on the other grains 30, 40, 50, 60 before.
  • the circular cross section of the channels 20 is not mandatory. This cross section can also be elliptical or different.
