Abstract

La désagrégation d'un projectile à l'intérieur du corps cible, notamment d'un projectile de chasse dans le corps du gibier après pénétration dans ce corps, détermine la production d'énergie du projectile et donc l'effet du coup de feu. Dans les projectiles à double noyau, le comportement de désagrégation et notamment le comportement de déformation des noyaux sont influencés de manière décisive par les propriétés des matériaux utilisés dans les noyaux. L'invention vise à améliorer la commande du comportement de désagrégation. A cet effet, dans un projectile à désagrégation partielle présentant deux noyaux, l'un (3) des noyaux est massif et est constitué d'un matériau apte à être un projectile et le deuxième noyau (4) est constitué de poudre (5) composée de matériaux métalliques ou céramiques, la poudre étant comprimée sans retassures.

Claims (14)

  1. Projectile à désagrégation partielle, en tant que projectile chemisé, le projectile (1) présentant deux noyaux, dont un noyau (3; 14; 24) est constitué d'un matériau massif, adapté à un projectile, caractérisé par le fait que le deuxième noyau (4; 22) est constitué de poudre (5; 23) de matériaux céramiques, par le fait que la grosseur de grain de la poudre (5; 23) est comprise entre 5 µm et 1 mm et que la poudre est comprimée sans formation de retassures.
  2. Projectile à désagrégation partielle selon la revendication 1, caractérisé par le fait que le noyau de projectile (3) massif forme l'arrière (12) du projectile (1).
  3. Projectile à désagrégation partielle selon la revendication 1, caractérisé par le fait que le noyau de projectile (24) massif est disposé à l'avant (25) du projectile (20) et forme la pointe de projectile (27).
  4. Projectile à désagrégation partielle selon une des revendications 1 à 3, caractérisé par le fait que la poudre céramique (5; 23) est de l'oxyde d'aluminium ou de l'oxyde de zirconium ou du nitrure de silicium.
  5. Projectile à désagrégation partielle selon une des revendications 1 à 4, caractérisé par le fait que lorsque la poudre est comprimée, elle est mélangée avec des liants ou avec une matière remplissant les retassures.
  6. Projectile à désagrégation partielle selon une des revendications 1 à 5, caractérisé par le fait que les noyaux de projectile (3, 4; 22, 24) sont préfabriqués et introduits dans les chemises (2; 15; 21) ou sont pressés dans la chemise.
  7. Projectile à désagrégation partielle selon une des revendications 1 à 6, caractérisé par le fait que le noyau massif est constitué de billes comprimées ou de granulés.
  8. Projectile à désagrégation partielle selon une des revendications 1 à 7, caractérisé par le fait que le noyau massif est constitué d'un matériau fritté.
  9. Projectile à désagrégation partielle selon une des revendications 1 à 8, caractérisé par le fait que la chemise de projectile (2, 15; 21) présente des points destinés à la rupture (11; 30).
  10. Projectile à désagrégation partielle selon la revendication 9, caractérisé par le fait que les points destinés à la rupture (11; 30) s'étendent dans le sens de l'axe de projectile (10; 29).
  11. Projectile à désagrégation partielle selon une des revendications 1 à 10, caractérisé par le fait que le matériau de la chemise de projectile (2, 15; 21) est du cuivre, les alliages de celui-ci, de l'acier plaqué, du fer doux ou des alliages zinc-étain.
  12. Projectile à désagrégation partielle selon une des revendications 1 à 11, caractérisé par le fait que le projectile (1; 20) présente une calotte (13; 32) dans la partie arrière (12; 31).
  13. Projectile à désagrégation partielle selon une des revendications 1 à 12, caractérisé par le fait que le projectile (20) présente une arête vive (33) sur son pourtour extérieur.
  14. Projectile à désagrégation partielle selon une des revendications 1 à 13, caractérisé par le fait que le projectile (20) présente des rainures de maintien (34) sur son pourtour extérieur.
