Research on the Characteristic of Optimal FlightRoute in the Terminal Area
-
摘要: 为了给飞机提供一条能满足多种指标要求的最优飞行轨迹,针对变分最优理论难以求解多指标优化问题,提出了命名为多次优化的方法,即将多要求的优化任务分成先后相继的多次任务,每次任务中选取一种不能边界转化的要求作为最优性能指标,而其余要求转化为边界条件.利用这一方法以时间、转弯次数、转弯角度为最优性能指标给出了终端区最优飞行轨迹的一般特征.Abstract: A method named multi-times optimization is presented to solve the multi-specification optimization problem,which is difficult to solve using the variational optimal theory.In the method several demands are reduced to some sub-tasks.In every subtask a demand that can not be transformed into bound condition is taken as performance specification for optimazation,and the other demands are taken as bound conditions.By means of the method,the arrival time,number of turn,turn angle of the aircraft in the terminal area are selected as performance specification separately,and the general character of optimal flight route in the terminal area is given.
