Abstract

The traditional shape of the base cavity of the projectile is a column. This paper focus on the influence of the little rake angle truncated-cone base cavity on the flow field of the projectile. With numerical method, the distributions of the flow field parameters and the drag coefficient of projectile with rake angle truncated-cone shape base cavity were obtained. Numerical results show that the recirculation region which is formed inside the base cavity played a key role in the aerodynamic resistance reducing of the projectile. The shape of the cavity with a little shrink angle has the minimal drag coefficient.
