The paper focuses on the influence of boattail on the flow field and aerodynamic force of the projectile. With the same base cavity, projectiles without and with boattail (boattail angle, 2°) are simulated numerically. The flow field parameters and the aerodynamic drag coefficient of models were obtained. The numerical results show that there is one more expansion wave is formed which is caused by the boattail configuration. This expansion wave weakens the one at the bottom of the projectile and decreases the base pressure of the projectile. The aerodynamic drag is decreased too.
