- In order to discuss the effect of the base cavity shape on the projectile aerodynamic force, projectile with different base cavity shape, column and truncated-cone (dilation and shrinkage one, with different incline angle " ", 15ø, 10ø, 5ø, 2ø), was investigated numerically. The distribution of the flow field and the aerodynamic drag of the projectile under a supersonic flow condition were obtained. Results show that the circumfluence plays a key role to effect the aerodynamic drag force of the projectile. Compare with the traditional base cavity shape (column one), dilation truncated-cone shape, increases the aerodynamic drag of the projectile, but shrinkage truncated-cone (any incline angle) is useful to reduce the aerodynamic drag of the projectile. And there is an optimum incline angle of the shrinkage truncated-cone.
