In order to research the influence of fuze shape on aerodynamic characteristics of hypersonic projectile, Fluent software was used to calculate coefficient of resistance of 57 mm caliber weather modification projectiles with point fuzes and base fuzes of different shapes. The curve of coefficient of resistance and Mach number with different shapes was got. The result shows that the shape of point fuze of 57 mm caliber weather modification projectiles has little influence on the coefficient of resistance:The coefficient of resistance has some difference when the top shape changes, but the influence is small overall. The coefficient of resistance increases when the length of the exposed parts of the base fuze reduces. When the base fuze has a prominent position, the coefficient of resistance of the projectile is close to the projectile whose length is equal to its full length.
