Definitions

  • the invention relates to a balancing projectile with conventional positive locking means between the projectile body and sabot.
  • Balancing projectiles of the known type also make it possible to combat difficult armored targets, against which projectiles based on the shaped charge principle are no longer sufficiently effective.
  • the penetration performance of the balancing bullets described in the introduction no longer meets all the requirements.
  • the invention is therefore based on the object of further increasing the penetration performance of the known balancing projectile in order to also enable the penetration of complicated multilayer armor.
  • FIG. 1 shows a balancing projectile 10 with a sub-caliber, essentially cylindrical projectile body 11, which ends at the front in a conical tip 16, which carries a tail unit 19 in the rear region 12 and which is surrounded in the central region 18 by a drive cage 14 consisting of segments.
  • the sabot 14 carries a guide belt 15, the function of which is known and therefore need not be explained further.
  • the projectile body 11 of the balancing projectile 10 has a larger diameter D over part of its length than the adjoining central and rear-side region 18, 12 of the projectile body 11.
  • the length L of the tip-side region 17 with an enlarged diameter D is expediently between 5% and 15%, preferably 10% of the total length of the projectile body 11, while the diameter D of the tip-side region 17 is between 10% and 15%, but preferably 12% larger is the diameter d of the central region 18 of the projectile body 11.
  • the increase in diameter of the tip-side region 17 of the projectile body 11 is achieved by a sleeve 20 (FIG. 2) which fits onto the front end piece of the cylindrical projectile body 11 is pressed on.

Abstract

Afin d'accroître la puissance de pénétration d'un projectile à inertie (10), une région (17) du corps (11) du projectile, contiguë à la pointe (16), est fabriquée sur une longueur (L) avec un diamètre (D) supérieur au diamètre (d) de la région (18) adjacente du corps (11) du projectile. De préférence, D est supérieur de 12% à d, et L couvre 10% de la longueur du projectile. Application contre des blindages multicouches.

Claims (5)

1. Projectile à effet cinétique comportant un corps de projectile (11) sensiblement cylindrique sous-calibré de rapport longueur/diamètre important qui se termine frontalement par une ogive conique (16), comporte postérieurement un empennage (19) et est entouré coaxialement dans une zone centrale intermédiaire (18) du corps par des moyens usuels d'assemblage par concordance de forme d'un sabot (14) constitué par des segments, caractérisé par les caractéristiques suivantes :
- le corps de projectile (11) présente dans une zone (17) située du côté de l'ogive, sur une partie de sa longueur, un plus grand diamètre que la zone centrale et la zone postérieure du corps de projectile, de diamètre usuel, qui s'y raccordent ;
- la zone côté ogive (17) de plus grand diamètre du projectile (10) est lisse et non entaillée et située devant le sabot (14) ;
- la zone côté ogive de diamètre agrandi (17) du projectile (10) se raccorde directement à la surface de base de l'ogive (16) de conformation conique et se raccorde, sous la forme d'un tronc de cône (13), à la zone centrale (18) de diamètre usuel du corps de projectile (11), et
- la longueur (L) de la zone côté ogive (17) de diamètre agrandi est comprise entre 5 % et 15 % de la longueur totale du corps de projectile (11).
2. Projectile selon la revendication 1, caractérisé en ce que la longueur (L) de la zone côté ogive (17) de diamètre agrandi représente environ 10 % de la longueur totale du corps de projectile (11).
3. Projectile selon la revendication 1 ou 2, caractérisé en ce que le diamètre (D) de la zone (17) côté ogive est supérieur d'une proportion comprise entre 10 % et 15 % à un diamètre usuel de la zone centrale (18) du corps de projectile (11).
4. Projectile selon l'une des revendications 1 à 3, caractérisé en ce que le diamètre (D) de la zone côté ogive (17) est supérieur d'une proportion d'environ 12 % au diamètre usuel de la zone centrale (18) du corps de projectile (11).
5. Projectile selon l'une des revendications 1 à 4, caractérisé en ce que la zone côté ogive (17) de diamètre agrandi du projectile à effet cinétique (10) est formée par un manchon (20) emmanché par pression sur le corps de projectile (11).
