Study on Aerodynamic Layout of Two-Dimension Trajectory Correction Projectile

To research aerodynamic layout of the two-dimensional correct projectile, the model of projectile under different aerodynamic layout was established. Various kinds of aerodynamic dates were obtained through aerodynamic simulation. Through the establishment of suitable for two-dimensional modified ballistic model of the projectile, the capability of correcting has been received for the different layouts of the rudder. The simulation results show, to meet the aerodynamic layout of the two-dimensional correct projectile and flight stability, the rudder is closer to the head of the projectile, the correction ability is better.
