Jet Velocity Profile Of Linear Shaped Charges

In a design of Linear Shaped Charges (LSCs), the deformation of the liner during projection (before collapse) is crucial information to understand the jet velocity profile and to optimize the performance of such device. In this paper, the jet velocity profile of LSCs is investigated based on a combination of two approaches of 1) a steady-state analytical approach to determine the liner collapse properties including the modified apex angle, collapse point angle, and jetting direction, and 2) a subsequent non-linear/non steady-state jet velocity profile from the collapse of a deformed LSC liner in consideration of the detonation front propagation along the laterally stretched core charge of LSCs.
