摘　　要：通过RECAT-CN标准对航空器进行重新分配,从而进一步提升机场的运行效率。针对不同类别组合下的尾流遭遇安全性定量评估的需要,首先构建了飞机遭遇尾涡强度消散和诱导滚转力矩系数模型,通过对典型机场交通流数据的统计,筛选出有代表性的典型机型,然后对RECAT-CN标准中不同类别组合下的滚转力矩系数进行计算和对比。对比结果表明,RECAT-CN标准在安全性上是可以接受的;计算结果表明,在现行尾流间隔标准下,不同类别组合的CRV存在较大差异,而在RECAT-CN标准下则比较均衡,表明RECAT-CN标准的间隔标准得到了优化,可见采用RECAT-CN标准更为合理。The current criterion is more conservative and it may tend to restrict the capacity improvement of the airports.It is necessity to use the RECAT-CN standard to reclassify the aircrafts according to the maximum taking-off weight and the wings span.It is just for the reason that we have chosen the following 8 typical aircraft types to analyze the safety and evaluate the calculation results under the RECAT-CN standard.In this paper,both a model of the aircraft encountering wake vortex intensity dissipation and a model of the induced rolling moment coefficient are constructed.What’s more,we have also chosen a typical airport and collected the relevant data,such as the meteorological data of a certain consecutive year,the radar recording and collecting data,the QAR data on board and so on.In addition,we have not only built up a mathematical model based on the Monte-Carlo calculation method,but also make an assessment on the safety trailing vortex suffered by the representative airplanes in different groups.And,finally,the calculation results of the rolling moment coefficients under the different classes of the combinations under the RECAT-CN standard can help to demonstrate that the RECAT-CN standard has to be acceptable and profitable in terms of safety.And,in addition,the calculation results also prove that,under the current wake interval standard,while there may exist a great difference in CRV in disparate category combinations.Nevertheless,under the RECAT-CN standard,such a kind of situation has been made more balanced,so as for the RECAT-CN interval standard to be made optimized.Thus,the research result of this paper should be recognized as a contribution to all the aircraft types in the sphere of the civil aviation transportation field at home,for it has been recognized as a reference to the realization and evaluation of the RECAT-CN standard.And,consequently,the RECAT-CN wake interval experiment operation standard has been admitted to be applicable in the airports of Guangzhou and Shenzhen at home.
