Definitions

  • the subject of the present invention is an explosive punctured cartridge-shell projectile which can be used in particular in a light individual shoulder weapon with a rifled barrel making it possible to obtain excellent marksmanship against point targets such as anti-tank weapons even protected by shields, helicopters operating at low altitude, or lightly or weakly armored personnel carriers such as mountain bikes.
  • a weapon provided with a long-stroke recoil brake which absorbs most of the recoil energy using a projectile according to the invention, can be distributed to the infantry at the rate of a few copies per company, thus considerably reinforcing its firepower and its means of action without reducing its mobility.
  • Explosive perforating projectiles of the conventional type are provided with a detonating device generally comprising an explosive material known as primary, that is to say capable of being ignited under the action of a relatively low energy shock to the impact of the projectile on the objective.
  • the detonator comprising the primary explosive charge is located inside the explosive charge consisting in turn of a stabilized secondary explosive material. This results in a high risk of accident in the event of an unexpected firing of the detonator.
  • the detonator is mobile and mounted outside the secondary explosive charge, means being provided for moving the detonator up to the interior of the secondary explosive charge after firing. It is therefore understood that such security devices are very complex.
  • the present invention allows the production of an explosive punctured cartridge-containing projectile having important qualities both in terms of safety of use and in terms of efficiency.
  • the projectile of the invention very simply solves the problem of the safety of the operation.
  • the structure of the projectile makes it possible to better distribute the masses by allowing a short total length and an advantageous ballistic shape having a relatively short cylindrical portion thus reducing the loss of speed on the trajectory.
  • the projectile of the invention also makes it possible to obtain stabilization on the trajectory with a small pitch of scratches, a relatively high initial speed for a limited recoil and allows the use of low propellant pressures of the order of 400 to 600 bars. .
  • the projectile of the invention makes it possible to project numerous fragments at impact at high speed, the range of these projections being however reduced, which has the advantage of not exposing the nearby troops to impacts. Furthermore, the lightness of the projectile of the invention allows the servant to transport a large amount of ammunition thus increasing the number of shots he can have.
  • the projectile of the invention comprises a self-destructive device which acts quickly, for example after approximately 2 seconds, after the start of the shot.
  • the cartridge-piercing explosive projectile of the invention comprises a body secured to a cartridge case and provided with gyration stabilization means cooperating with a rifled barrel, a warhead secured to the body and a head rocket.

  • the explosive charge consists exclusively of secondary explosive material stabilized so that the body of the projectile of the invention does not include any primary explosive material even after the start of the shot.
  • a stabilized explosive mass which it is agreed to call secondary explosive substance, is not ignited for example when a bullet passes through it.
  • a projectile launched at a much higher speed approximately twice that of such a bullet, is capable, by striking the secondary explosive material, of causing its explosion even in the absence of primary explosive material.
  • the invention is therefore based on the use of this phenomenon, the ignition of the explosive charge consisting exclusively of stabilized secondary explosive being caused by the fragments of the metallic element closing the rear end of the explosive column, fragments which are forcefully projected through the empty channel located in the axis of the explosive charge.
  • the metallic element for closing the explosive column preferably has a concave profile directed towards the front end of the channel.

  • great safety is obtained in using the projectile of the invention since, before the start of the shot causing the projectile to turn, the axial channel is completely closed by the aforementioned bolt.
  • An unexpected ignition of the explosive column causing the bursting of the metallic closing element therefore does not risk igniting the explosive charge of the projectile since the debris of the metallic element is stopped by the bolt and cannot reach the explosive charge.
