摘要
航路交叉点的承载能力是决定航路容量的关键因素,而研究交叉点的潜在冲突与航路构型是提高交叉点容量的有效方法。首先根据国内现有几大主要航路构型的运行现状,提出构型存在的主要问题并加以总结。然后建立基于影响航段的交叉航路冲突模型,分别讨论了航路交角、航班流率、安全间隔3方面对平均冲突数的影响。最后比较分流法和降维法两种扩容方法,通过容量模型和数值分析计算,把三维交叉航路降为二维简单交叉航路,把"米"字型航路改为"井"字型航路,验证了降维法更具有可行性。研究表明,"井"字型航路可以增大航路网的现有容量,是提高空域利用率和运行效率的有效方法。
mIntersection capacity is vital to air route capacity,and potential conflicts and configuration of intersection are important to enlarge the route capacity.A brief introduction of air route configurations operating in China were presented first including functions,pros and cons and main problems.Then the potential conflict model around the airway intersection was proposed by introducing the variables of the angle of air route,flows of aircraft along route 1 and 2 in aircraft per hour,and minimum lateral radar separation,which analyzes the relationship between the conflicts and variable above.Based on these,conclusion can be drawn that the change of the crossing angle has the function relationship with the conflicts;flows of aircraft along routes 1 and 2 has different influence about the number of conflicts.It also discusses two ways to adjust the structure of intersection,distributary and simplification.The result shown by MATLAB that it can reduce flight conflicts by adjusting the intersection geometry,which is an effective and feasible method to expand the capacity of the airway network and improve the operating efficiency.
