摘　　要：在对自由飞行进行适当的简化建模后,引入常用于计算流体力学Delaunay网格生成方法,对于空中交通冲突进行检测,能够同时检测到空域内的多架飞机间的冲突。该方法能同时探测多架飞机之间发生的冲突和潜在冲突,减少不必要的距离探测,从而减少了计算量,同时较传统的方法也大大地减少了运算量。最后通过仿真模拟,显示此方法的优越性。该方法可以用于以后的空域设计和管理,使空域结构更为合理、稳固。在今后的设计使用上,这种方法有可能减轻飞行员和管制员主观性的工作负荷。This paper imported the Delaunay triangulation method, often used in computational fluid dynamics （CFD） in the conflict detection in free flight environment after simplification. Compared with the traditional method, it can save a lot of time wasted on unnecessary comparison and calculation. At last, it calculates and analyzes a model in this way, and proves its efficiency and superiority. This mathematical approach is being investigated for the specification and management of future airspace, achieving a more solid architectural basis for airspace design. This approach has the potential to significantly reduce the subjectivity when attempting to model controller and pilot workload, an important requirement in future designs.
