N2 - When the projectile enters into the water at high velocity, the impact force will be huge, therefore, it is necessary to protect the projectile. In this paper, polyurethane foam is selected to study its protective properties for water-entry projectile. The water-entry test was designed to compare the numerical simulation results, in order to verify the feasibility and the validity of the model. In particular, the numerical simulation method was used to compare the motion and response characteristics of unprotected and protected projectile. The results demonstrated that the polyurethane foam has good protective properties and comparing the protective effect of different density polyurethane foam by numerical simulation methods, it can be seen that the better protection is achieved at a density of 0.17 g/cm3 and 0.40 g/cm3.
