Research on Climb Trajectory of Ramjet Engine Powered Missile

针对以冲压发动机为动力的战术导弹的爬升弹道,首先考虑了发动机的特性,对导弹加速爬升的性能进行了系统分析,获得了导弹加速爬升过程中剩余功率和燃油消耗量随飞行状态变化的规律。利用这些规律形成遗传算法弹道优化的初始种群,仿真证明可以高效地收敛获得最优弹道。在优化中综合考虑了飞行时间和耗油量,对不同优化目标的弹道进行了优化和比较。为以冲压发动机为动力的战术导弹的弹道设计提供了理论参考。

For the climb trajectory of a ramjet powered tactical missile,considering the feature of ramjet engine,the climb and speed-up performance of a missile are systematically analyzed.The characteristic that extra-power and fuel consumption varied with the flight condition in the climb and speed-up course is obtained.The initial population of trajectory optimization with genetic algorithm can be formed with this characteristic.Simulation proves that the population could converge and reach the optimal trajectory ...
