Abstract: Based on the general scheme of an anti-tank missile,a thrust vector control device is equipped in front of the missile,that realizes its turning at the end of trajectory and upper armor attack.The TVC array model is established,and the relationship between TVC and flight coefficients is analyzed.By means of the discrete quadric programming method,the optimization of TVC scheme is made.The results indicate that the optimized TVC scheme avoids rising of missile-body,and increases the impact angle,which reduces the requirement on the warhead.
