Drift Velocity Computations for Shaped-Charge Jets

Abstract

This work provides quantitative support for the assumption that jet curvature is the major cause for nonideal jet penetration. Jet radiographs were analyzed to ascertain the component of jet velocity normal to the axis of symmetry of the charge for each jet particle. This nonideal velocity component is the drift velocity. The drift velocity distribution determined in this manner was imposed on the jet in a computer simulation of the penetration process. The computer code, referred to as PENJET, was employed to generate penetration- standoff curves using the data from a specific round. This curve depicts the penetration-standoff performance for the single round as if it could be shot repeatedly at a variety of standoffs. The curve could then be compared with the actual datum for the round.
