Abstract In order to improve the available overload and fast overload response of air defense missile, the application of trajectory-controlled thrust vector technology in foreign air defense missiles is analyzed．The method of matching design of trajectory-controlled thrust vector device and missile shape is studied by using jet disturbance factor．The method of moment balance iteration is used to design the action point of trajectory-controlled thrust and the arrangement of missile center of gravity．The influence of trajectory-controlled thrust vector device on the load, strength and overload characteristics of missile is analyzed and the corresponding measures are put forward．
