Abstract

Procédé de sautage sous-marin à l'aide d'un dispositif à charge explosive profilée. Le dispositif a charge profilée comprend une enveloppe divisée, par un cône métallique 4, en une chambre 5 contenant une charge explosive, et en une seconde chambre comprenant une cavité conique 7 et un espace 6 de développement de l'onde de pression de la charge explosive. Des trous 9 et 10 sont réalisés dans l'enveloppe, à la partie inférieure de l'espace 6, de manière à permettre à l'eau de pénétrer par cet espace, puis d'en être chassée par introduction d'air comprimé avant la mise à feu. Application : saurages sous-marins.
