中文摘要:近年来,四维轨迹预测与优化功能成为了飞行管理系统(Flight Management System,简称FMS)技术的研究热点。航迹预测结果的准确性直接关系着飞机的参数指标,同时也关系着飞机运行的经济性,甚至决定飞机的安全性。从飞机运行的成本角度出发,根据运行成本建立飞机运行的代价函数模型,分别对巡航阶段的速度和高度建模,将代价函数作为优化对象对四维航迹预测结果进行优化,总结出一套最经济巡航速度以及最经济巡航高度的计算方法,为民用飞机四维航迹预测的优化提供了切实可行的理论参考。
英文摘要:In recent years, the function of Four-Dimensional(4D) trajectory prediction and optimization has become a hot research topic of Flight Management System (FMS) technology. The accuracy of track prediction results is directly related to the parameters of the aircraft, as well as the economy of the aircraft operation, and even determines the safety of the aircraft. From the point of view of aircraft operation cost, this paper establishes the cost function model of aircraft operation according to the operation cost, models the speed and altitude in the cruise phase respectively, optimizes the four-dimensional track prediction results with the cost function as the optimization object, and summarizes a set of calculation methods for the most economical cruise speed and the most economical cruise altitude. The paper provides a practical theoretical reference to optimize the four-dimensional track prediction for civil aircraft.
