摘要

为了实现终端区内空管单位燃油消耗的有效评估,结合综合航迹数据采用数据挖掘技术,提出一种基于航迹数据的终端区真空速的估算模型.首先应对综合航迹数据处理,提出了对综合航迹处理的方法;通过在中国气象数据网上获取机场上空风的数据,利用插值法建立机场上空风场的模型;分析航行速度三角形,推导出真空速计算模型.最后分别以离场和进场的QAR数据,用Matlab对真空速进行仿真估算.结果表明:方法能够有效地利用综合航迹数据进行真空速的估算.%In order to evaluate fuel consumption of air traffic control in terminal area effectively,combined with a comprehensive trajectory data using data mining technology,estimated airspeed model of terminal area on comprehensive trajectory data is proposed.Firstly,trajectory data processing is proposed to processing method;By taking over meteorological data of the airport,wind field model over the airport is established by interpolation method;Analyzing sailing speed triangle airspeed calculation model was deduced.At last,the QAR data of departure and approach are used to simulate and estimate the true airspeed.The results show that the method based on comprehensive trajectory data can be used effectively to estimate the true airspeed.
