Abstract

Base cavity plays a key role in reducing the aerodynamic drag of the projectile. In the paper, two kinds of base cavity shape for projectile are simulated by using axisymmetric Navier-Stokes equations. Under the supersonic flow condition, the distribution of the flow field parameters and the aerodynamic drag of the projectile were obtained. The numerical result shows that, in the paper, the shape of base cavity has little effect on the flow field of the projectile. But compare with the column cavity, the truncated-cone cavity shape reduces the aerodynamic drag of the projectile.
