Abstract
A shaped charge system controlled by an electronic safe and arm device located outside a system chamber comprises a billet of explosive fill material in the chamber, a waveshaper disposed in the explosive material, and a detonator and firing module disposed within the waveshaper.
Claims15
A shaped charge system comprising:
- a casing defining an interior chamber and having a forward end and a rearward end;
- a shaped charge liner disposed in the chamber;
- a billet of explosive fill material disposed in the chamber rearwardly of the liner;
- a waveshaper having a predetermined external contour based on desired shaped charge functional characteristics and disposed in the explosive material between the rearward end of the chamber and the liner;
- and
- a detonator and firing module disposed entirely in said waveshaper.

A shaped charge system comprising:
- a billet of explosive fill material;
- a waveshaper disposed in the explosive material;
- and
- a detonator and firing module disposed entirely within said waveshaper.
1 more element
A method for initiating detonation waves in a shaped charge system comprising:
- in response to a trigger signal, initiating an electrical detonation signal from an electronic safe and arm device located outside a chamber containing a billet of explosive material;
- and
- in response to said electrical detonation signal, creating detonation waves in said billet of explosive material from a location entirely within a waveshaper embedded in the explosive material.
