| Abstract: | In this paper the terminal correction technique of a mortar projectile by using the impulse rockets is studied. A simple correction trajectory model is established. The method of pulse choice and the scheme of retrofire algorithm are presented. After analyzing the important factors that influence the correction capability, the algorithm of optimization design is determined. The simulation and the optimization design of a mortar projectile by using Powell optimization algorithm and exterior penalty function method are presented. The simulation result shows that the optimization method is useful for devising the structure and enhancing the capability of correction ammunition. |
