Abstract

This paper focus on the improvement of the aerodynamic drag reducing of the base cavity configuration on the projectile under supersonic flow condition. Projectile with two sorts of irregular shape of the base cavity which is distinguished from the traditional column base cavity is investigated numerically. Flow field parameters and the aerodynamic drag of the projectile were obtained. Results show that, by the changing of the base cavity shape, the aerodynamic drag of the projectile could be weakened.
