Research on Aerodynamic Characteristics and Correction Ability of Two-dimension Trajectory Correction Projectile of Different Canard Rudder Profile Shape

摘要

To research the effect on the canard rudder aerodynamic layout for the projectile correction, the steering gear model under different aerodynamic layout was established. Various kinds of aerodynamic parameters were obtained through simulation. Through the establishment of the ballistic model of suitable for less spin correction projectiles, the capability of correcting has been received under the different layouts of the canard rudder. The simulation results show that the correction capability was better when the canard shape was asymmetric rudder shape. To meet the whole shells aerodynamic layout, flight stability and control, the possible use of asymmetric rudder shape.
