摘　　要：本文以仪表着陆系统(ILS,instrument landing system)和建立要求特殊授权的所需导航性能(RNP AR,required navigation performance authorization required)进近(EoR,established on RNP AR)混合程序为研究对象,探讨混合进近下跑道进场容量。首先,研究了飞机尾流消散和运动规律,提出混合进近条件下安全间距计算方法;其次,根据混合进近运行特征,建立混合进近平行跑道进场容量模型;最后,以昆明长水国际机场为例,构建全空域机场仿真模型,对模型进行验证,并在此基础上,设置多个运行场景对影响混合进近条件下跑道进场容量的因素,包括程序结构、机型和RNP AR能力飞机比例进行分析。研究结果表明:容量评估模型能够对混合进近运行下平行跑道进场容量进行精确、客观的评价;且固定半径转弯(RF,constant radius to fix)航段半径越大,跑道进场容量越大;RF航段半径为4~7 km时,RNP AR能力飞机比例越大,跑道进场容量越大;中型机比例越多,跑道进场容量越大。Taking instrument landing system(ILS)and established on required navigation performance authorization required(RNP AR)(EoR)mixed approach procedure as the research object,the runway approach capacity under the mixed approach is discussed.Firstly the aircraft wake dissipation and movement law are studied,and a safety distance calculation method is proposed under mixed approach conditions.And then the approach capacity model of mixed approach parallel runway is established according to the characteristics of mixed approach operation.Finally,taking Kunming Changshui International Airport as an example,total airspace and airport simulation model is established to verify this model.On this basis,various operational scenarios are set up to analyze the factors affecting the runway approach capacity under the mixed approach conditions,including procedure structure,type of aircraft and aircraft proportion of RNP AR capability.The results show that the capacity evaluation model can evaluate the approach capacity of parallel runway under mixed approach operation accurately and objectively.And the larger the segment radius of constant radius to fix(RF),the greater of the runway approach capacity.When the RF segment radius is 4-7 km,the aircraft proportion of RNP AR capability is higher,the runway approach capacity is larger.And the proportion of medium-sized aircraft is higher,the greater of the runway approach capacity is greater.
