Definitions

  • the technical field of the invention is that of ignition charges for an igniter tube for propellant charges having a central (cylindrical) channel.
  • the propellant charges fitted to the shells and missiles are ignited by means of an igniter associated with an igniter tube.
  • the igniter tube is formed of a combustible tube closing an ignition charge based on high-combustion ignition powder. This igniter tube is placed in the channel of the propellant charge.
  • the patent application FR-A-2 593 905 describes an ignition charge placed in a combustible tube consisting of a stack of tablets of agglomerated ignition powder. These assemblies for igniter tubes require on the one hand the manufacture of agglomerated powder tablets, and on the other hand their placement in the fuel tube.
  • the ignition charge, placed in the fuel tube is made of a pyrotechnic material based on an agglomerated powder.
  • combustible caps are distributed over the length of said tube. These combustible caps, about ten microns thick, rupture with the rise in pressure in the tube generated by the combustion of the ignition charge. Thus the hot gases generated by the ignition powder can reach, from the start of ignition, the parts of the propellant charge located in the vicinity of the openings resulting from the breakage of the caps.
  • Ignition charges based on prior art powder tablets have several disadvantages (of which said skilled artisan is aware).
  • the operation of filling the fuel tube with the ignition charge is a delicate operation, with reference both to the handling technique and to the pyrotechnic risk (the ignition powder is classified in risk division 1.1 within the meaning of within the meaning of the UN GHS classification (Globally Harmonized System of Classification and Labeling of Chemicals (UN)). special tools to be automated.
  • the ignition charge is introduced into the tube in mixture with a collodion to obtain ( in situ ) tablets, the evaporation time of the collodion solvent is long due to the confinement of the charged collodion in the tube.
  • the fuel tube has a length equivalent to that of the propellant charge channel, but the ignition charge occupies a volume in relation to its mass.
  • the mass of the charge may vary according to the ignition specifications and/or the nature of the powder.
  • the ignition charge volume specified for ignition may be lower than that of the propellant charge channel.
  • the ignition of the propellant charge is therefore not always homogeneous in the tube, and therefore synchronous over the length of the channel. This then deviates from the ideal conditions of almost instantaneous ignition of the entire (internal) surface of the propellant charge.
  • the patent application FR-A-2 725 781 proposes to replace the tablets of agglomerated powder by an ignition material comprising an ignition composition in powder form (typically black powder) deposited on a flexible support sheet, which is then advantageously rolled up on itself in order to be inserted into a combustible tube to form an igniter tube. So that the powder (which is just placed on the flexible support) does not fall to the bottom of the igniter tube, it is imperative to coat the powder composition with another flexible sheet (called a screen sheet), at least one of the screen and support sheets. being coated with glue.

So that the powder (which is just placed on the flexible support) does not fall to the bottom of the igniter tube, it is imperative to coat the powder composition with another flexible sheet (called a screen sheet), at least one of the
  • This method makes it possible to better distribute the powder charge in the channel of the ammunition and facilitates the dismantling of the ignition material with respect to the ignition material of agglomerated powder.
  • the ignition material described in the patent application FR-A-2 725 781 therefore proposes a technical solution to the problems posed by ignition materials based on powder tablets.
  • the flexible sheet and the screen sheet are made of paper, nitro paper, fabric, plastic or aluminum. These materials do not contribute significantly to the energy input of the ignition charge.
  • the spatial distribution of the ignition energy of the charge is only obtained by the distribution and the volume of the piles of powder. It is not contemplated to vary the composition of the ignition material to optimize the spatial distribution of the energy of the ignition charge.
  • the configuration possibilities in terms of level and the spatial energy distribution of the pyrotechnic objects of the patent application FR-A-2 725781 are therefore limited and controlled solely by the mass and the spatial distribution of the piles of pulverulent powder.
  • the invention relates to an ignition charge according to claim 1 and to methods for obtaining such an ignition charge according to claims 11 and 12.
  • the invention therefore relates, according to a first aspect, to an ignition charge for a channel (cylindrical) propellant charge igniter tube.
