Abstract

Abrégé Elément peu vulnérable de munition explosive comportant un chargement explosif bi-c omposition et procédé d'obtention d'un effet d'éclats. La présente invention a pour objet un élément performant et peu vulnérable de munition explosive constitué d'une enveloppe 1 contenant un chargement explosif constitué d'une couche interne 2 en explosif composite dont la charge contient au moins un explosif nitré organique, revêtue d'une couche coaxiale adjacente périphérique 3 en composition pyrotechnique moins sensible constituée d'une matrice polymérique chargée dont la charge contient au moins un oxydant minéral ou un explosif nitré organique. L'interface entre les deux couches 2 et 3 présente une section droite étoilée. L'invention a également pour objet le procédé d'obtention d'un effet d'éclats par détonation de la couche 2, réaction de la couche 3, puis rupture de l'enveloppe dûe à la pression des gaz formés.
