Patent

CA 2644646

Container (10) is generally cylindrical except for a longitudinal concave groove (11) extending along its entire length. Upon explosion, the contour of this groove (11) results in a focussing effect on the wall material due to the oblique angle at which the expanding cylindrical detonation wave front impacts upon its inner wall. This produces the forging of a rough rod-like projectile (111) which, being coherent, maintains its velocity and consequently travels much further than the randomly shaped projectiles (101).

Selon la présente invention, le récipient (10) est généralement cylindrique à l'exception d'un renfoncement longitudinal (11) se prolongeant sur toute sa longueur. Au moment de l'explosion, la forme du renfoncement (11) entraîne un effet de concentration sur le matériau de la paroi en raison de l'angle oblique selon lequel l'onde de choc cylindrique se propage et frappe la paroi intérieure. Il en résulte un projectile de forme schématiquement tubulaire (111) qui, logiquement, maintient sa vitesse, et par conséquent, va plus loin que les projectiles de forme aléatoire (101).
