Abstract
A shaped charge assembly (10) comprises a housing (20), first shaped charge (24), a wave shaping relay charge (44) and a second shaped charge (30) located in the housing. The assembly (10) is configured such that a first active element formed by initiation of the first shaped charge (24) causes detonation of the wave shaping relay charge (44), which in turn causes initiation of the second shaped charge (30) to form a second active element. The first active element moves beyond a second end (25) of the housing to cause damage of a first kind to an external target and the second active element also moves beyond the second end to cause damage of a second kind to the target.
Claims19
A shaped charge assembly comprising:
- a first shaped charge and a second shaped charge mounted coaxially towards a first end of the assembly;
- a relay charge mounted coaxially with the first and second shaped charges towards a second end of the assembly;
- and
- the assembly being such that a first active element formed by initiation of the first shaped charge moves axially in a direction towards the second end and causes detonation of the relay charge, which in turn causes initiation of the second shaped charge, the first active element moving axially beyond the second end to cause damage of a first kind to a target and a second active element formed by initiation of the second charge moving axially beyond the second end to cause damage of a second kind to the target.
The assembly as claimed in claim l wherein the first shaped charge comprises a first body of explosive and a first liner having a first caliber and wherein the second shaped charge comprises a second body of explosive and a second liner having a second caliber.
A method of damaging a target comprising:
- initiating a first shaped charge mounted towards a first end of an assembly to form a first active element moving axially in line with a main axis in a direction towards a target;
- utilizing the moving first active element to initiate a relay charge mounted towards a second end of the assembly;
- utilizing the relay charge to initiate a second shaped charge mounted towards the first end of the assembly to form a second active element also moving axially in line with the main axis in the direction towards the target;
- causing the first active element to cause damage of a first kind to a the target;
- and
- causing the second active element to cause damage of a second kind to the target.
The assembly as claimed in 5 wherein the first caliber is equal to the second caliber.
