By changing the wing sweep angle, the variable wing sweep aircraft can achieve the best flight state under different flight speeds. To complete the folding and unfolding movements of the wing skin when the wing sweep angle changes under the single drive condition, we present a new driving mechanism for the variable sweep aircraft based on the planar compound linkage mechanism. To solve the problem of the combination of function generation and motion generation, the compound mechanism is divided into three sub-mechanisms. Furthermore, the vector loop equation of the compound mechanism is established and the movability of the mechanism is analyzed. Based on the vector loop equation, we propose a synthesis method to judge the movability and optimize the performance of the mechanism by using the optimization algorithm and kinematic analysis software. Finally, an example is presented to validate the effectiveness of the proposed method. The driving mechanism for the variable sweep aircraft is designed by using the proposed method. The designed mechanism meets the movability requirement and size constraint, and has the minimum envelope area, which prove the effectiveness of the method.
