Definitions

  • the invention relates to a propellant charge powder for tubular weapons according to the preamble of claim 1
  • the DE 35 00 068 Cl relates to a mono- or polybasic propellant powders under input rate of 0.0 'dioxy azobenzene for improving the mechanical properties to
  • DE 30 33 519 C2 relates to a rocket fuel for a usually low pressure range during combustion, statements about the relevant for propellant powder
  • propellant powder according to DE 22 60 259 A is a propellant charge for rockets and not a propellant charge for Guns
  • This propellant charge like all two-base propellants in general, is strongly temperature-dependent in the temperature range of interest.
  • the invention is based on the object of proposing a propellant charge powder for tubular weapons which has a small temperature coefficient in the temperature range from -50 ° C. to + 70 ° C.
  • the invention enables the production and use of propellant powder with a low temperature coefficient. efficient. That means: such a propellant powder enables the firing of barrel ammunition with almost constant values of maximum pressure and bullet speed in the entire temperature range from - 50 ° C to + 70 ° C.
  • the invention relates to the following propellant powder: glycidyl azide polymer, (GAP) -,
  • HTPB Hydroxy terminated polybutadiene
  • CAB Cellulose acetate butyrate, (CAB) -bound nitramine propellant powder with the dinitro-diaza plasticizer according to the invention and nitrocellulose propellant powder, NC, which consists of nitramines, nitrocellulose and dinitro-diaza plasticizers or nitrocellulose and dinitro-diaza plasticizers, with or without explosive such as nitroglycers (Ngl) or diglycol dinitrate (DEGN).
  • NC nitrocellulose propellant powder
  • NC which consists of nitramines, nitrocellulose and dinitro-diaza plasticizers or nitrocellulose and dinitro-diaza plasticizers, with or without explosive such as nitroglycers (Ngl) or diglycol dinitrate (DEGN).
  • NENA nitratoethylnitramine
  • PolyNIMMO poly S-nitratomethyl-S ' -methyloxetan
  • Polyglyn poly glycidyl nitrate ester
  • the Dinitro-diaza plasticizer consists of the components
  • the propellant charge powder according to the invention is changed by customary measures, such as changing the grain geometry, so that the original curve 6 as curve 6 1 with its turning point 7 1 lies against the pressure limit 10, this means a considerable increase in output of 10 to 20% based on the usual Propellant powder according to curve 5
  • the pressure limit 10 is defined by the permissible weapon use pressure
  • the propellant charge powders according to the invention moreover have good mechanical properties down to the range of approximately ⁇ 50 ° C. There is no brittleness when cold
  • the invention is not limited to the exemplary embodiments. It can be used without further ado with single- to polybasic propellant charge powders. Also with three-base propellant charge powders based on nitroguanidine.
  • the invention can also be used with propellant charge powders consisting of a mixture of the energetic plasticizer according to the invention with a conventional, Non-energetic plasticizers
  • the invention also relates to propellant powders which consist of a propellant charge powder according to the invention and one or more similar admixed powders with conventional temperature behavior, for example such a similar formulation, but with conventional plasticizers
