基于航线对象方法的四维航迹建模与优化
4D Trajectory Model and Optimization Based on Path Object
摘要
Abstract
Trajectory based operation was the development trend of new generation air traffic control operation. In order to describe the trajectory of civil aircrafts precisely and efficiently ,the seven new trajectory model based on path object was proposed. Horizontal trajectories were built depending on the flight plan, control instruction and geographical distributing of navaid, the requisite main parameter, including ascension rate, descent rate, thrusting and cruise Mach, for vertical profiles modeling were simplied reckoned and optimized , a whole 4D trajectory was obtained. Finally,a comparison between a departure simulation data with the actual flight data shows that the 4D trajectory model based on path object can describe the spacial position of the aircrafts accurately, and resolves the trajectory prediction problems that exist in terminal area describe dynamic trajectory of the terminal area better. It has positive effect on the practical traffic flow adjusting and controling.关键词
