US12644680 - Shaped charge assembly

The disclosure relates to a shaped charge assembly including a casing and a liner, the liner being a hollow dome forming a hollow space, coaxially arranged around a longitudinal central axis (x) of the shaped charge assembly. The casing and the liner together defines a volume including an explosive. The liner includes an internal surface facing the hollow space and an external surface facing the volume including the explosive. A tangent of the internal surface and a base plane (y) formed at a base end of the liner, the base plane being perpendicular to the longitudinal central axis (x), forms an angle (α) of at least 100°.

Claim 1

1 . A shaped charge assembly comprising a casing and a liner, said liner being a hollow dome forming a hollow space, coaxially arranged around a longitudinal central axis of the shaped charge assembly, wherein the casing and the liner together define a volume comprising an explosive, wherein the liner comprises: an internal surface facing the hollow space, an external surface facing the volume comprising the explosive, and wherein a tangent of the internal surface and a base plane (y) formed at a base end of the liner, said base plane being perpendicular to the longitudinal central axis (x), forms an angle (α) of at least 100°. an internal surface facing the hollow space, an external surface facing the volume comprising the explosive, and wherein a tangent of the internal surface and a base plane (y) formed at a base end of the liner, said base plane being perpendicular to the longitudinal central axis (x), forms an angle (α) of at least 100°.
