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 gun 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 is based on the object Specify processes for the production of propellant powder, in which the maximum pressure curve is flattened in a simple manner in the temperature range for which the weapon is intended is achieved.
  • the invention is essentially based on the idea of conventional ones one-, two- or three-base powder with special Surface treatment of desensitizers, being only Desensitizers are used that have no or at most have a low tendency to migrate.
  • the desensitizers according to the invention are inert or energetic polymers or large-volume monomers, that practically do not migrate, as well as energetic monomolecular Substances or mixtures of both components, to reduce energy loss to a level that no significant loss of performance when firing at weapons.
  • the surface treatment of the propellant powder can in be done in a known manner, the desensitizers in sprayed onto a treatment drum as a solution or as an emulsion or with the help of an impregnation process, in which the Propellant powder in the treatment solution for a certain period of time is incubated, applied.
  • 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%
  • 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 takes place 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.
  • a single-base 7-hole TLP C / M 0800 with nitrocellulose manufactured as an energy source and Centralit I as a stabilizer was in an emulsion of nitroglycerin Water in a rotating drum at 30 ° C until clear incubated the solution.
  • the powder is then subjected to a second treatment in a Palamoll 632 emulsion subjected to water.
  • 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 which has been surface-treated according to the invention compared to the untreated propellant powder Composition a reduced sensitivity to special loads, such as those at hostile fire may occur.
