Shaped charge with an axial channel

A shaped charge with an axial channel is considered. The charge is initiated by an impact of an annular plate. As a result, the shaped charge is initiated at all points of the domain shaped as a ring. The impact plate material and parameters (velocity, thickness, width, and distance covered by the plate) that ensure stable penetration of the shaped charge are determined. The results obtained can be used to develop a composite (e.g., “tandem”) shaped charge of the “base-head” type (the charge located farther from the target is first initiated, followed by initiation of the charge located closer to the target).
