Trajectory Optimization for Unpowered Gliding Submissile

Longer range and larger impact angle are the requirements of modern anti-armor missiles being studied. In order to achieve this goal, a method for trajectory optimization is introduced by transferring the design of trajectory optimization to solving nonlinear programming problems, and the gliding trajectory as well as the terminal guidance trajectory is optimized. The improved flight model of the unpowered gliding submissile is simulated, and results show that the optimized trajectory is much better with larger range and almost perfect impact angle by 85deg. What´s more, shorter miss distance and smaller overload of the hit point are achieved at the same time.
