摘　　要：主要介绍了应用最优过程理论计算飞机最优飞行轨迹的数学模型和计算方法。针对变参数的处理方法进行了研究 ,给出了计算时间最短水平机动运动的数学模型 ,并提出了一种简单适用的两点边值问题数值计算方法。通过实例计算表明该方法是正确的 ,所得最优飞行轨迹参数没有波动现象 ,曲线光滑。It is introduced that the application of optimum process theory to flight trajectory optimization. In this paper, it has studied the method of dealing with changing parameter. It is derived for the optimal flight trajectory calculation model from minimum theory. A simple calculation method is applied in calculating differential equations of two points boundary value question.The example calculating shows that the method is correct. Optimum flight trajectory parameters don't have wave and are smooth.It has practical value very well for research air battle motion.
