Aim To study the dynamic variation of the missile static stability. Methods The aerodynamics and trajectory integrated design method was used. After the aerodynamic parameters were computed, the missile trajectory was calculated, and the dynamic variation of the missile static stability was researched. Through the adjustment in aerodynamic configuration and its geometrical parameters of the missile, the aerodynamics computation and trajectory design were made again. Results and Conclusion By means of the example of the wing's movement relative to the missile's body, the dynamic varying range of the static stability meeting the requirements of the trajectory characteristics was designed. It delivers a design method for the missile static stability.
