Optimizing Design of Aerodynamic Configuration and Parameters for Glide Extended-range Projectile

In order to increase the glide distance of glide extended-range projectile,the aerodynamic configuration and parameters should be optimized.The different aerodynamic configurations of glide extended-range projectile were researched.An approach of aerodynamic parameters optimization was established,taking lift-drag radio as optimizing target function.The simulation results show that the aerodynamic parameters of glide extended-range projectile confirmed by this method can provide enough stability and well flexibility.The matching between stability and flexibility,canard rotating angles and balanceable attack angles is better.The results provide an academic guidance for aerodynamic configuration and parameters design of glide extended-range projectile.
