摘　　要：该文以脉冲发动机作为某型迫弹修正执行机构,进行末段弹道修正研究,建立了简易修正弹道模型,给出了脉冲选择和点火算法方案,分析了影响修正能力的关键因素,确定了优化设计数学模型。通过采用Powell优化算法结合外点罚函数法进行了仿真计算,结果表明:该文给出的修正机构数学模型对简易修正弹的结构研制和性能改进具有实用价值。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.
