Abstract
A shaped charge for efficiently transferring energy from an explosive material to generate a deep penetrating jet. The shaped charge liner is formed with a hemispherical first section combined with an elongated second section. The liner second section can be formed as a truncated cone, trumpet, or other shape. The hemispherical first section collapses to generate a high velocity jet portion, and the second section collapses to generate an elongated, deep penetrating jet portion which follows the higher velocity jet portion.
Claims16
A shaped charge activatable by a detonator to generate a deep penetration jet, comprising:
- a housing;
- a recess defined by an inner housing surface within said housing, wherein said recess has an open end and a closed end;
- a high explosive within said recess which is activatable by the detonator to generate a detonation wave;
- and
- a liner having a first section substantially formed as a hemisphere collapsible by said detonation wave to form a first penetration jet segment moving in a selected direction, wherein said liner further has a proximate second section between said first section and said recess open end which is collapsible by said detonation wave to form a second penetration jet segment moving in said selected direction for cooperating with said first penetration jet segment to form the deep penetration jet.
A shaped charge for extending the length of a material penetrating jet, comprising:
- a housing;
- a recess defined by an inner housing surface within said housing, wherein said recess has an open end and a closed end;
- a high explosive within said recess which is activatable by the detonator to generate a detonation wave;
- a first liner section substantially formed as a hemisphere having an apex and having a second end between said apex and said recess open end, wherein said first liner section is collapsible by said detonation wave to form a first penetration jet segment moving in a selected direction;
- and
- a second liner section between said first liner section second end and said recess open end, wherein said second liner section comprises a different material than said first liner section and is collapsible by said detonation wave to form a second penetration jet segment moving in said selected direction for cooperating with said first penetration jet segment to form the deep penetration jet.
