摘要
为提高航空器航迹预测的准确性, 考虑航路限制、成本指数以及航空器性能限制, 提出一种基于多目标约束的航空器下降段航迹预测方法。根据航空器性能数据、特征参数、航路限制及成本指数要求, 采用动力学理论动态分析并预测各航段多维状态数据。利用航空器数据记录器中的一条真实航迹的起飞、爬升和巡航数据预测优化其下降航迹。仿真结果表明, 对比真实航迹, 预测航迹及多维状态数据可随成本指数及航路的约束动态调整, 满足航路限制并提高了燃油利用率。
Abstract
In order to improve the aircraft trajectory prediction accuracy,considering route restrictions,cost index and aircraft performance restrictions,a multi-objective constraint-based aircraft descent flight trajectory prediction method is proposed.According to aircraft performance data,characteristic parameters,route restrictions and cost index requirements,dynamics theory is used to dynamically analyze and predict multi-dimensional state data for each flight sector.The take-off,climb and cruise data of a real trajectory in the aircraft data recorder are used to predict and optimize its descent trajectory.The simulation results show that,compared with the real trajectory,the predicted trajectory and multi-dimensional status data are dynamically adjusted with the cost index and the constraints of the route,which meets the route restriction and improves the fuel efficiency.
