The premature separation of saboted projectiles undergoing high‐mach‐number in‐bore acceleration is investigated. Results from a simplified numerical model for the problem are presented. Measured short‐term velocity history for a typical projectile is used to describe the motion of a nonuniformly accelerating piston. Two numerical algorithms for calculating the shocked flow in tront of the accelerating piston are presented. Mach number and pressure time histories for the flow afford corrective input to the sabot design process. © 1993 John Wiley & Sons, Inc.
