Definitions

  • the invention relates to improvements to projectiles, in particular grenades intended to be launched by means of a weapon, for example a rifle, using conventional bullet cartridges.
  • Known projectiles of this type are generally provided with a head containing an explosive charge, this head being extended by a tubular tail which can be threaded onto the barrel of a rifle.
  • This method of projectile launching requires in a first application, the use of special propellant cartridges without bullet, which causes difficulties in terms of stewardship, a lack of operational efficiency during the transition from normal shooting to the rifle at launch. of a projectile and a serious danger for the user in the event of a mistake in the choice of ammunition or the state of the weapon when launching a projectile.
  • the launching of projectiles can be obtained using a normal bullet cartridge, however such an application requires a bullet trap placed in the tubular tail.
  • bullet traps are generally of delicate and expensive construction because they must, with maximum security, catch and maintain the ball at the start of the stroke without harmful deformation, or even rupture, of said tubular tail.
  • these bullet traps are constituted by a succession of screens intended to brake and immobilize the bullet or by fairly considerable metallic masses.
  • These bullet traps have, among other things, the disadvantage of a significant weight and size.
  • the launching of projectiles can also be obtained by means of a normal bullet cartridge, the projectiles having for this purpose, from one end to the other, an axial passage allowing the bullet to pass through the projectile or grenade and escape to the outside.
  • the invention therefore relates to a ball pass, more especially a mobile pass ball, making it possible to carry out such a make-up charge.
  • the bullet pass according to the invention for a projectile comprising a head extended by a tubular tail and traversed by an axial bore opening into said tubular tail, is mounted in a chamber in the rear part of said axial bore, respectively the rear part. of the sleeve extending said axial bore, this ball pass is arranged in such a way that, in the storage position of the projectile, the pass-ball is in said chamber at a certain distance from the bottom of said chamber, enclosing at its circumference, a booster charge.
  • Figure 1 a projectile comprising a head 1 and a telescopic tail 2 with empennage 3.
  • the tail 2 is made in two parts, in particular a part 4 integral with the head 1 and a part 5 which can slide along from part 4.
  • the head 1 is fixed on the front end of a sheath 6 around which is provided a body 7 constituting the explosive charge of the projectile, the rear end of said sheath 6 being provided with a sleeve 8 by which said part 4 can be immobilized in said part 5 while waiting for the passage of the ball.
  • the rear end of the sleeve 8 is closed by a ball-passing plug 11 around which an auxiliary load 12 is placed.
  • the bullet stopper 11 When it is assembled, the bullet stopper 11 is compressed in the chamber 13 so that, on the one hand, it is held in place without other means than the pressure which it exerts on the wall of the chamber 13 and that , on the other hand, it provides a perfect seal, the ball pass can not be moved in the chamber 13 by a very considerable force, for example the force exerted on the pass ball by a launching ball.
  • the ball pass 11 is housed in the chamber 13 at a distance D from the bottom 14, the thickness E of said ball pass 11 being greater than the length L of said make-up load 12, of such a way that this make-up charge is completely enclosed in the circular cavity 15 by the bullet holder 11 itself.
  • the pass-through 11 will advantageously be made of a flexible material, respectively elastic, natural or synthetic, preferably with a hardness of between approximately 30 Shore A and approximately 70 Shore D.
  • the movable ball pass according to the invention will be moved forward, in contact with the ball 16 with the ball pass 11 in order to thus release, even before the total penetration of the bale 16 through the ball pass 11, the make-up charge 12 so that the effect of the deflagration of the make-up charge 12 is added to the effect of the combustion gases of the ordinary cartridge used to launch the projectile by means of the bullet 16.
  • the thickness E of the pass-through 11 is slightly greater than the width L of the cavity 15 enclosing the make-up charge 12, while, in order to be able to release this charge make-up after moving the ball pass 11 forward, the distance D between the ball pass 11 and the bottom 14 of the chamber 13 is greater than half the difference between the thickness E of the ball pass 11 and the width L of the cavity 15.
  • a mobile bullet-carrier according to the invention enclosing an auxiliary charge during its storage and releasing this auxiliary charge during the launching of the projectile of which it is a part, can be produced in different forms.
