Abstract: In order to optimize the design of the forward and back centering sabots which are commonly used in the Davis Gun system, a penetration model of rigid penetrator with sabot is established based on the Forrestal penetration model, and the influences of the relative sabot mass, the connection strength between sabot component and projectile and the impact velocity on projectile penetration are analyzed. The results indicate that the penetration depth increases obviously with the increase in sabot mass. The effect of the sabot mass on the penetration depth augments gradually while the effect of the connection strength on the penetration depth get smaller with the improvement of the impact velocity.
