Abstract: The friction between the rear sabot and bore surface in the rectilinear-chamber phase and the impact resistance between the sabots and bore surface during the projectile squashing in the conic-chamber at a high speed in the conic-chamber phase are analyzed. The mathematical models of resistance are set up based on the special structure of conic-chamber gun and projectile. The resistance-length curve, press-length curve, and velocity-length curve are obtained with the mathematical models. And the calculation results are consistent with the experimental results. The research can provide references for the optimization design of conic-chamber gun’s interior ballistics and projectile’s structure.
