Definitions

  • the invention relates to a method for producing one, two or three-base propellant powders for gun ammunition according to the features of the preamble of the claim 1.
  • two or three-base propellant powders for barrel weapon ammunition such as powders made of nitrocellulose, nitric acid esters (e.g. nitroglycerin, diethylene glycol dinitrate, Butane triol trinitrate, metriol trinitrate, triethylene glycol dinitrate), Alkylnitratoethylnitramine, nitroguanidine, hexogen, Oktogen 3-nitro-1,2,4-triazol-5-one (NTO), hexanitrohexaazaiso-wurtzitan (CL20) or mixtures of such powders or such powders provided with additives (e.g.
  • DE 33 46 287 A1 is a propellant charge known, by mixing homogeneous with inhomogeneous Powder proportions have an approximately constant burning behavior in the area around the main usage temperature is achieved.
  • a disadvantage of this known propellant powder however, among other things, that the homogeneous and inhomogeneous powder components are very precisely coordinated have to be. Otherwise you get propellant powder, which have different shooting behavior from lot to lot.
  • the present invention has for its object a method for manufacturing to indicate propellant powder, in which a flattening of the Maximum pressure curve in the temperature range for which the weapon is intended, is achieved. This object is achieved by the features of Claim 1 solved.
  • the invention is essentially based on the idea of customary one, two or to treat three-base powder with special desensitizers, whereby only Desensitizers are used which have little or no at all Have a tendency to migrate.
  • the desensitizers according to the invention are special Materials that practically do not migrate and only reduce energy loss to one Reduce a small amount that is not worth mentioning when firing at weapons Losses in performance.
  • the surface treatment of the propellant powder can be carried out in a manner known per se take place, the desensitizers in a treatment drum as a solution or sprayed on as an emulsion or using an impregnation process in which the Propellant powder in the treatment solution for a certain period of time is incubated, applied.
  • Polyethers Polybutadienes, polyamides, energetic materials (e.g. Poly-Nimmo, Polyglyzidyl azide), alkylnitratoethylnitramine (e.g. methyl-NENA, ethyl-NENA, butyl-NENA), Dinitrodiazaalkanes, nitric acid esters (e.g. diethylene glycol dinitrate), Butanetriol trinitrate, triethylene glycol dinitrate, metriol trinitrate), bis (2,2-dinitropropyl) Acetal / Formal (BDNPA / F).
  • energetic materials e.g. Poly-Nimmo, Polyglyzidyl azide
  • alkylnitratoethylnitramine e.g. methyl-NENA, ethyl-NENA, butyl-NENA
  • Dinitrodiazaalkanes nitric acid esters (e.g. diethylene glycol din
  • the propellant powder (TLP), on which the surface treatment according to the invention is to be carried out, is the double-base TLP L 5460 introduced for 120 mm KE ammunition, which has the following composition: nitrocellulose 59.5% nitroglycerin 14.9% diethylene glycol 24.8% Acardite II 0.7% Others 0.1%
  • a 4% ethanolic solution from Ethyl-NENA comes in four Guess the TLP in a conventional treatment drum L 5460 sprayed on.
  • the surface-treated powder is dried and then various shelling investigations subjected.
  • TLP propellant powder
  • SLP surface treatment will be carried out in turn based on the two-base TLP L 5460 described above.
  • the Treatment with 1.5% of the polymer is done in a rotating Treatment drum at 45 ° C. Spread over four servings the emulsion becomes successive over a period of five hours added while the solvent evaporates.
  • 3 and 4 are the bombardment results of this powder in a 40 mm simulator from -40 to + 63 ° C compared to one untreated L 5460 shown.
  • Here again are the maximum pressure and the muzzle velocity depending plotted by temperature.
  • the following table 1 shows the specific energy for the powders described in the above-mentioned two exemplary embodiments.
  • the desensitizer 1 bears on the surface 2 of the respective powder grain denoted by 3 in FIGS. 7-9.
  • the inner holes 4 of the TLP also become partial (Fig. 8) or completely (Fig. 9) covered by the desensitizer 1 or can even be completely closed by the desensitizer become.
  • This coating of the propellant particles 1 the desired change of the Burning behavior of the propellant powder and thus to the observed reduction in the temperature gradient.
  • the method can be used for both known 1-, 7- and 19-hole TLPs with cylindrical as well as with hexagonal or rosette-shaped External geometry can be applied.
  • the powder treated according to the invention has surface treatment compared to the untreated propellant powder the same Composition a reduced sensitivity to special loads, such as those at hostile fire may occur.
