Abstract

La presente invencion describe un forro (30) para una carga moldeada (10), que dispone de un ápice hemisférico y una porcion de faldon (38) la cual termina en un borde de faldon circular (40), con un diámetro (D) de borde de faldon. El ápice (36) posee un radio de curvatura menor que el diámetro (D) de borde de faldon, y el espesor (Tac) de la moldura en el centro del ápice (36) es mayor que el espesor (Ts) de la moldura en el borde de falda (40), con el espesor ahusándose entre el ápice y el borde del faldon en una transicion suave y curvilínea. El forro (30) puede ser empleado en una carga moldeada (10), que comprende un explosivo moldeado (26), el cual ha sido comprimido hasta por lo menos el 95% de su densidad máxima teorica y está contenido en un carcasa (12) con un cubierta (20), hecha de un material pulverizable, tal como cerámica. Se proporciona una cámara (22) en al base de la carcasa (12) para alojar una pella pre-comprimida de iniciacion (24), donde la carcasa dispone de una ranura (42) formada en su base (14), para alojar y retener en ella un miembro explosivo lineal en estrecha proximidad con la pella de iniciacion (24), retenida dentro de la cámara.
