摘　　要：拉萨机场是我国西南地区最重要的高高原机场,保证航班正常运行,提高机场运行效率十分必要。本文对拉萨机场气温变化特征和夏秋季航班时刻分布规律进行统计分析,得出拉萨机场夏季下午时段航班量减少的主要原因在于“高海拔+高温”特性导致的飞机发动机推力下降。运用空客PEP软件,对选装CFM56-5B7或IAEV2522-A5这两种发动机的A319机型在拉萨机场的最大复飞限重进行了计算,研究了两种发动机选型、三种不同的着陆复飞襟翼构型对改善飞机最大复飞限重的影响。结果表明通过选装高高原性能优良的发动机和优化飞机进近着陆复飞程序,可以有效提升飞机最大复飞限重。Lhasa airport is the most important high plateau airport in southwest China.Therefore,it is necessary to ensure normal operation of flights and improve the efficiency of airport operations.In this study,changes in the characteristics of the outside air temperature(OAT)at Lhasa airport and the relationship between the OAT distribution and flight schedule at Lhasa airport in summer and autumn seasons are analyzed.The results indicate that the key reason for a decrease in the traffic volume during summer afternoons at Lhasa airport is the loss in engine thrust of aircraft owing to“high altitude+high temperature”characteristics.In this study,the maximum go-around weight(MGAW)for Airbus A319 models equipped with CFM56-5B7 or IAEV2522-A5 engines at Lhasa airport is calculated using Airbus PEP software.Furthermore,the effects of two types of engine options and three different landing go-around flap configurations are compared for improving the MGAW of the aircraft.The results indicate that the MGAW can be significantly improved by selecting the engine with good performance at high plateau airports and by optimizing the approach and landing go-around program.
