Abstract
A variable stand-off distance explosive cord assembly for a casing is disclosed. In various embodiments, the assembly includes an explosive cord configured for positioning at a stand-off distance from the casing and a thermally responsive material configured to vary the stand-off distance from a first distance to a second distance.
Claims18
A variable stand-off distance explosive cord assembly for a casing, comprising:
- an explosive cord configured for positioning at a stand-off distance from the casing;
- a first thermally responsive material configured to vary the stand-off distance from a first distance to a second distance, the first thermally responsive material positioned between the casing and the explosive cord;
- and
- a second thermally responsive material, the second thermally responsive material positioned on a side of the explosive cord opposite the casing and having a coefficient of thermal expansion greater or lesser than the coefficient of thermal expansion of the first thermally responsive material.
