参考了规划飞机最佳爬升轨迹的图解法—能量高度法。采用NSGA-Ⅱ算法求解了飞机最快爬升轨迹,即各能量高度单位剩余功率(Ps)值最大的轨迹。并通过对跨音速段的俯冲角度θ与过渡段的时间t的关系进行分析,求解出跨音速段的最佳俯冲角。从而解决了能量高度法在等能量高度发生跃升或者俯冲时不适用的问题。并以此对超音速飞机最快爬升轨迹跨音速段进行了修正。
Refer to the graphic method of planning the best climb trajectory of the aircraft - the energy altitude method. The NSGA-Ⅱ algorithm is used to solve the fastest path of aircraft climb, that is, the path with the largest residual power (Ps) value in each unit of energy. Through the analysis of the relationship between the subduction angle θ of the transonic section and the time t of the transition section, the optimal subduction angle of the transonic section is obtained. Thus solving the problem that the energy height method does not apply when the energy level is jumped or subducted. In this way, the transonic section of the fastest climb path of supersonic aircraft was modified.
