Abstract

Perforator med rettet ladning, og som omfatter et hus (2), et høyeksplosiv (3) og en foring (5) med en innsatsforing (6), idet høyeksplosivet befinner seg mellom f6ringen og huset. Under bruk vil høyeksplosivet få foringen og innsatsen til å bryte sammen og bevirke at det dannes to skjærende stråler. Innsatsen kan hovedsakelig dekke overflaten av foringen eller bare delvis dekke foringen, slik som tuppartiet av foringen eller basispartiet av foringen. Alternativt kan innsatsen variere i tykkelse langs overflaten av foringen. Tykkelsen til foringen kan typisk være mellom 1% og 10% av f6ringsdiameteren, og tykkelsen til innsatsen kan være mellom 1% og 200% av tykkelsen til foringen. Innsatsen kan fremstilles under fremstillingen av foringen, men innsatsen er fortrinnsvis en ettermontert gjenstand.
