Aerodynamic Characterization of a Ballistic-Correction Bullet

Obtaining the aerodynamic parameters of a ballistic-correction bullet is crucial for improving ballistic correction efficiency and enhancing shooting accuracy. In this study, a numerical simulation method is utilized to analyze and calculate the aerodynamic characteristics of the bullet. The focus is on investigating the changes in aerodynamic parameters when the rudder wings are in both unexpanded and expanded states, as well as analyzing the impact of deflection angles on the bullet's aerodynamic characteristics. The simulation results demonstrate that the bullet exhibits favorable aerodynamic performance and static stability when the rudder wings are unexpanded, leading to improved ballistic correction efficiency during flight. Moreover, the results indicate that in the expanded state of the rudder wings, increasing the deflection angle enhances the impact on the bullet's aerodynamic characteristics, resulting in more pronounced changes and stronger correction capabilities. This research provides valuable insights into the aerodynamic characteristics of ballistic-correction bullets.
