Abstract

L'invention concerne un détonateur utilisant un étranglement, ménagé le long d'une colonne d'explosifs, pour créer des conditions permettant d'induire une détonation. Le détonateur de cette invention comprend une enveloppe cylindrique à l'intérieur de laquelle sont ménagés un alésage et deux parties coaxiales d'une charge d'explosifs, une colonne d'un diamètre élevé et une colonne d'un diamètre réduit, ces deux parties étant raccordées au niveau d'un étranglement, ou grâce à la diminution du diamètre dudit alésage. Ce détonateur, qui comprend également un ensemble amorceur, permet en particulier de provoquer une déflagration et une détonation d'explosifs haute température en toute sécurité, ces explosifs étant par exemple HNS, PYX, BRX, et NONA. L'invention concerne également un procédé permettant de provoquer une détonation, ainsi que des méthodes destinées à provoquer une déflagration dans une partie d'une colonne d'explosifs confinée d'un diamètre élevé. Chaque déflagration se produit sur la longueur de la partie de la colonne présentant le diamètre le plus élevé, jusqu'à ce que l'étranglement provoque une explosion, ladite partie de la colonne présentant le diamètre le plus élevé devenant ainsi une partie coaxiale d'un diamètre inférieur.
