Improved Drift Velocity Computations for Shaped-Charged Jets

Abstract

A new technique has been devised to calculate the inherent interdispersion of shaped-charge jet particles (called drift velocity), which offers substantial improvements over a technique originally proposed in a previous report: Drift Velocity Computations for Shaped-Charge Jets. ARBRL-MR- 3306(AD-A 133 756). The original formulation calculated jet particle drift velocities from jet radiographs in a way which was biased by warhead tilt, and was thus of limited value in assessing the quality of the shaped-charge jet. The new technique is able to predict the magnitude and direction of the reference particle drift velocity and warhead tilt in a rational way. As a consequence of being able to remove tilt induced drift velocities from the calculation, a measure more closely related to the quality of the jet may be determined. Keywords: Transverse velocity; Dispersion.
