Study on the hydrodynamic characters of high-speed water-entry projectiles with different shapes

Abstract

The hydrodynamic characteristics, such as the displacement, velocity, acceleration, resistance coefficient and attack angle of three kinds of projectiles are analyzed by numerical simulation. The small taper angle projectile has the smallest resistance coefficient and attack angle. The results of this study can provide some reference for the hydrodynamic shape design of the projectile penetrating water with high-speed.
