Definitions

  • the invention relates to a projectile comprising a bullet pass, this projectile being of the type comprising a head 1 extended by a tubular tail, said head being traversed by an axial bore opening into the tubular tail, this bullet pass being mounted in a chamber. in the rear part of said axial bore, respectively the rear part of a sleeve extending said axial bore, a make-up charge surrounding the pass-through.
  • Known projectiles of this type are generally provided with a head containing an explosive charge, this head being extended by the tubular tail which can be threaded onto the barrel of a rifle.
  • the ball pass can be easily crossed by bullet and closes after the passage of the ball to prevent any passage to propellant gases.
  • a projectile of the kind specified above is described in US-A-4,846,070 (cf. the preamble of claim 1).
  • the make-up charge is located in the chamber, around the end of the pass-away from the bottom of the chamber. For safety reasons in the storage position, this end and the load extra are covered by a disc which at the same time closes the room and which is destroyed during launch.
  • the invention relates to a ball pass for carrying out such a make-up charge.
  • the booster charge is housed in a cavity which surrounds the chamber, the bullet pass being, in the projectile storage position, in said chamber at a distance from the bottom of this chamber and completely closing the above-mentioned cavity.
  • the thickness of the pass-through being slightly greater than the width of the cavity, the distance, the thickness and the aforementioned width being measured in a direction parallel to the longitudinal axis of the projectile, the distance between the pass-through and the bottom 14 of the chamber being such that the ball pass is movable in the chamber, under the action of the ball, between the aforementioned storage position and a position against the bottom of the chamber, position in which the pass bullet leaves partially open the aforementioned cavity.
  • BE-A-804,791 describes a device for launching a grenade using a rifle, this device comprising a bullet trap formed by a mass of steel in a chamber at the front end of the casing tube extending the body of the grenade. This mass is retained by a copper washer at a distance from the bottom of this chamber and is surrounded by a make-up 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 secured to 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 off by a bullet stopper 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 so as to release, even before the total penetration of the bale 16 through the ball pass 11, the make-up load 12 so that the effect of the deflagration of the make-up load 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 forwards, 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.
