摘　　要：对某飞行器对面攻击的飞行弹道特点和运动规律进行了分析,重点对影响全弹道最大的爬升段,进行了推阻、升阻和操稳等特性以及优化目标及约束条件的分析,通过对爬升律设计和推力调节规律设计两方面的优化,建立了理论模型。在以往的开环弹道设计方法之外,引入更为便利和准确的虚拟导引方法对爬升律进行建模,可以实现爬升段相对于爬升终点的闭环调节和分析,通过建立余气系数与高度/马赫数等相关因素之间的调度关系,得出了爬升段弹道的优化规律,并进行了弹道仿真对比分析,更好地满足了工程设计需求。Certain aerocraft＇ s characteristics of trajectory and movement are analyzed, especially in the climbing period because these influence the whole flight trajectory supremely. Based on the analysis of characteristics of thrust, lift, resistance and stability, the optimization model is established including optimization goal, restriction terms and optimization rules. Two aspects of climbing rules and thrust regulating rules are designed, and virtual guidance rule is adopted instead of open-loop designing method, so the climbing terminal could be regulated more exactly and conveniently. By trajectory simulation and comparison, the optimization designation meets higher performance.
