Abstract

The attitude deflection and trajectory bending of truncated cone-shaped projectile will occur during water-entry process. The process is analyzed theoretically and the attitude deflection equation is obtained. AUTODYN software is used to simulate the water-entry process of truncated cone-shaped projectile. Based on the simulation results, an empirical formula describing trajectory of centroid is proposed, and its accuracy is verified by experiments. The vertical water entry test of projectile is designed, and the impact velocity and motion process of projectile are recorded by high speed camera. The experimental results show that the attitude deflection equation obtained from theoretical analysis is reliable, and the numerical simulation and empirical formula of centroid trajectory based on numerical simulation is reliable.
