In order to obtain optimal aerodynamic shape parameters of guided projectiles equipped with canards(GPEC), an optimization model of aerodynamic shape for GPEC is established. An aerodynamic shape optimum design method is proposed for GPEC based on some aerodynamic parameters requirements. By optimizing the aerodynamic shape parameters of an example, the results show that: the GPEC has proper stability with optimal aerodynamic shape; the stability matches the maneuverability very well, and the angle of the canard deflection matches the balance angle of the attack. This method can be used as a powerful tool of the aerodynamic shape design for this kind of projectile.
