终端区多机协同进场下的飞机性能参数优化方法

为了降低多条航路上下降至同一航路点的多架飞机最后巡航阶段和下降阶段的运行总成本,同时要确保飞机的飞行安全,研究了多架飞机下降至同一航路点时降低总运行成本的参数优化方法。首先,介绍了飞机性能参数计算方法;其次,为了提高寻找飞至同一航路点各架飞机使得总运行成本最低的合适指示空速的计算速度,建立了考虑间隔约束的参数优化模型,并通过精英保留的遗传算法进行优化运算;最后,用某型民用飞机对建立的模型进行算例仿真。结果表明,该模型能准确计算出各架飞机使总运行成本最低的指示空速,对航空公司处理多架飞机下降至同一航路点降低总运行成本有较大的指导意义。

Aircraft performance parameter optimization method for multi-aircraft cooperative approach in terminal area

In order to reduce the total operating cost of several aircraft descending to the same route point in the final cruise and descent stages,and to ensure the flight safety of each aircraft,the parameter optimization method for reducing the total operating cost of multiple aircraft descending to the same route point was studied.Firstly,the method of calculating aircraft performance parameters is introduced.Secondly,in order to improve the speed of calculating the appropriate indicated airspeed for finding the lowest total operating cost of each aircraft flying to the same airway point,a parameter optimization model considering interval constraints is established,and the optimization operation is carried out by elite-preserved genetic algorithm.Finally,the optimization operation is carried out by using elite-preserved genetic algorithm.The model is simulated by a civil aircraft.The results show that the model can accurately calculate the indicated airspeed of each aircraft with the lowest total operating cost,which has great guiding significance for airlines to reduce the total operating cost by processing multiple aircraft descending to the same airway point.
