Optimizing design of glide trajectory for glide extended-range projectile

Based on the analysis of the glide extended-range projectile with canard configuration in flight,the glide trajectory model of the glide extended-range projectile was established,and the glide trajectory was optimized by keeping the biggest lift-drag ratio in glide flight.The formula of lift canard rotating angles and balanceable attack angles were obtained.The simulated computing analyse was made of glide ballistic characteristics.The simulation results show that the glide trajectory falls slower than the falling trajectory of ordinary ballistic with the effect of extending range prominent.
