Definitions

  • the invention relates to piercing projectiles comprising, as described in patent FR-A 477 375, a main projectile of the caliber of the weapon and in which is formed at least one axial bore open towards the front, and, housed in said bore, an auxiliary projectile with the caliber of said bore, a propellant charge being disposed between the bottom of this bore and said auxiliary projectile.
  • a triggering device is provided for igniting the propellant charge in order to cause the firing of the auxiliary projectile before or at the time of the impact of the main projectile on its aim.
  • a proximity detonating fuse triggering device is well known (see in particular the patent GB-A 2 110 799).
  • Such piercing projectiles the piercing effect of which is therefore caused, on the one hand by the auxiliary projectile and on the other hand by the main projectile, are known and the invention aims to give them additional destructive properties, in particular by as regards explosive and / or incendiary effects, which are known and which are described in particular in patent FR-A 2 356 906.
  • the main projectile comprises on the one hand at least an explosive and / or incendiary charge located in the main projectile in front of the auxiliary projectile firing thereof, and on the other hand means for firing this explosive and / or incendiary charge designed to fire automatically as soon as the auxiliary projectile has been fired.
  • these means for igniting the explosive and / or incendiary charge are sensitive to the passage of the auxiliary projectile in the axial bore formed in the main projectile.
  • Such firing means can then be constituted by at least one channel connecting the axial bore formed in the main projectile to the explosive and / or incendiary charge.
  • the axial bore may include scratches whose pitch is such that the angular velocity generated on the auxiliary projectile is added to the angular velocity communicated by the main projectile to said auxiliary projectile.
  • securing means to make the auxiliary projectile, before firing, integral in rotation with the main projectile, such securing means may be constituted by a self-tightening conical fitting.
  • This self-locking conical fitting between the auxiliary projectile and the main projectile also plays the role of temporary retention means of the auxiliary projectile in the axial bore and allows an optimization of the setting in speed (axial speed and rotational speed) of the auxiliary projectile during of the firing of the propellant charge.
  • the invention consists, apart from the arrangements just mentioned, of certain arrangements which are preferably used at the same time and which will be more explicitly described below.
  • a triggering device is provided for igniting the propellant charge 4 in order to cause the firing of the auxiliary projectile 3 before or at the time of the impact of the main projectile 1 on its goal.
  • the aforesaid rear shoe 7 and the aforesaid front cover 8 are connected to each other at a junction plane P, the outside diameter of the projectile being Ion the invention at this junction plane P being less than the outer diameter of the rear shoe 7 at its annular bulge area 7b and the outer diameter of the front cap 8 at its annular bulge area 8b, and this in such proportions that the hollow connecting the two aforesaid annular bulging zones is not in contact with the barrel by which the projectile according to the invention is fired.
  • the axial bore 2 of such a projectile is therefore formed in the central core 6 which has at its front a mouth 9 covered by the tip 10 of the front cap 8 which, at this mouth 9, has a small thickness.
  • the main projectile 1 comprises one or preferably several explosive and / or incendiary charges 11 located in the main projectile 1, in front of the auxiliary projectile 3 before firing, means for igniting this explosive and / or incendiary charge 11 generally designated by the reference numeral 12 being provided and arranged to fire automatically as soon as the auxiliary projectile 3 has been drawn.
  • recesses 13 are regularly spaced circumferentially, and formed in the central core 6, each of these recesses 13 containing an explosive and / or incendiary substance and being closed by the inner wall of the front cover 8.
  • the means 12 for firing these explosive and / or incendiary charges 11 are advantageously produced so as to be sensitive to the passage of the auxiliary projectile 3 in the bore 2.
  • At least one channel 14 is provided connecting the axial bore 2 to each explosive and / or incendiary charge 11 housed in its housing 13.
  • the firing of the propellant charge 4 causes the auxiliary projectile 3 to fire and, as soon as this auxiliary projectile 3 has passed the outlet of the channels 14 in the bore 2, the hot gases penetrate the channels 14 and ignite the Explosive and / or incendiary charges housed in the accommodation 13.
  • the axial bore 2 may include scratches 15 whose pitch is such that the angular speed generated on the auxiliary projectile 3 is added to the angular speed communicated by the main projectile 1 to said auxiliary projectile 3.
  • securing means to make the auxiliary projectile 3, before firing, integral in rotation with the central core 6 of the main projectile 1; such means are formed by self-locking conical engagement 16 between the rear part of the auxiliary projectile 3 and the bottom of the axial bore 2 and formed in the central core 6.
  • This self-locking conical engagement 16 between the auxiliary projectile 3 and the central core 6 also plays the role of temporary retaining means of the auxiliary projectile 3 in the axial bore 2 and allows an optimization of the speed setting (axial speed and rotational speed ) of the auxiliary projectile 3 when the propellant charge is fired.
  • a projectile in accordance with the invention can be produced in all calibers.
  • any caliber less than the 12.7 mm (.50) caliber, without being excluded from the field of application of the invention can be ruled out at least in the first stage.
  • the architecture of the projectile according to the invention could be designed more freely given the dimensions that it would then be possible to give to the constituents of the projectile.
