Abstract

Et perforerende system som har en perforerende modul omfattende et enhetlig legeme av eksplosiv. Eksplosivet er oppbevart innenfor en ikke eksploderende foring eller kledning med formede fordypninger og et dekke over det. Fordypningene som vil omformes til eksplosivt formede gjennomtrengere (EFP-er) ved detonasjon, har en omkretsform som muliggjør forbedret pakketetthet, for eksempel en sekskantet omkrets som fører til forholdsvis lite "dødt rom" hvor ingen perforerende gjennomtrengere blir frembragt. I drift sørger modulen for et forholdsvis tett skytemønster og i hovedsak redusert mengde av rester etter detonasjonen som kunne tette til perforeringene og/eller kreve avhjelpende opprensning eller gjentatt perforering.
