The heading reversal of air-to-air missile is designed based on relaxed static stability and aerodynamic torque generated by static instability of air-to-air missile, and the kinematic sign is proposed. The slender body theory and the viscous crossflow theory are used to investigate the aerodynamic characteristics involved in the redirection of air-to-air missile. The slender body is assumed to be incapable of achieving the proposed kinematic sign of completing redirection, and it is necessary to increase control techniques such as aerodynamic rudder surface or direct force. The aerodynamic characteristics of a fin-body configuration are obtained for the angle of attack from 0° to 180°, and the trajectory and attitude of air-to-air missile during the process of heading reversal are calculated. The results show that the heading reversal is finished in 1.15 s, and the process of redirection is safe, quick and stable. Finally, some key technologies are discussed in the process of heading reversal.
