Abstract
航空运输业新技术的发展推动了基于航迹的精细化管理,使航空器冲突解脱成为重要课题.以时空棱锥为基础,深入探究航空器巡航阶段下的时空棱锥运行机理,旨在研究航迹冲突解脱策略.结果显示飞行速度、时间预算和起终点距离对航空器运行轨迹具有重要影响.通过分析航空器的时空运行特征和冲突解脱需求,提出了综合考虑时间窗口、安全间隔等约束条件的解脱策略,并采用3D Dijkstra算法搜索满足约束条件的最短时空路径,通过调整航速和航向获得多种解脱方案.各方案在燃油消耗和空域资源利用等方面存在差异,选择时需综合考虑实际利益和管制偏好.研究为航空器冲突解脱提供了参考,有助于提高航空运输系统的效率和安全性.
The development of new technologies in the aviation industry has propelled the large advance-ment of trajectory-based fine management,thus underscoring aircraft conflict resolution as a significant topic.This study focuses on building a new method based on Space-Time Prism(STP)to investigate a strategy for resolving trajectory conflicts during aircraft cruising.Next,the proposed method shows that flight speed,time allocation,and start-to-end distance have a notable influence on aircraft trajectories.Then,through an analysis of the aircraft's space-time characteristics and conflict resolution requirements,we propose a new comprehensive strategy,which considers essential constraints like time windows and safety intervals.In addition,the 3D Dijkstra algorithm is used to find the shortest STP path under con-straints,resulting in multiple conflict resolution solutions achieved by adjusting speed and heading.The solutions have different results with different fuel consumptions and airspace utilization.Therefore,when selecting the most appropriate approach,comprehensive consideration of practical interests and control preferences is very important.Last,this research offers some valuable insights for aircraft conflict resolu-tion,contributing to improved efficiency and safety within the aviation transportation system.
