中文摘要:
      机型分类方法是尾流间隔计算的基础和依据,我国现行机型分类标准与ICAO相同,均依据飞机重量进行分类。在欧美国家提出的尾流标准重新分类(RECAT)中,依据最大起飞重量和翼展等参数对机型分类和尾流间隔标准进行了重新调整。首先介绍了现行机型分类方法、RECAT 1.5、RECAT EU机型分类方法,然后依据飞机环量计算模型,对国内43种常用机型进近着陆阶段的环量进行计算分析,提出基于环量的RECAT NEW机型分类方法。计算表明,RECAT NEW机型分类方法中,各机型分类区间平均绝对偏差和标准差均小于RECAT 1.5和RECAT EU中各分类区间的该值,可更好地满足RECAT研究需要,具有实际参考价值。
英文摘要:
      The classification of aircraft types is the foundation and basis in the wake turbulence separation calculation. Aviation control institutions now in our country are all just the same to ICAO in the classification standards of aircraft types, i.e. the weight of aircraft. In the RECAT proposed by Europe and the United States, the classification of aircraft type and standard of wake turbulence separation have been readjusted according to some parameters such as maximum takeoff weight and wingspan. In this paper, priority is given to the current classification method of aircraft type adopted by aviation control institutions and RECAT 1.5, RECAT EU classification method of aircraft types in order to achieve the establishment of the aircraft circulation calculation model, calculate and analyze the circulation in the approach and landing stage of forty three common aircraft types, thus putting forward a RECAT NEW aircraft type classification in terms of circulation. The calculation indicates that in the RECAT NEW classification method of aircraft type, the average absolute deviation and standard deviation of the classification range for various aircraft types are less than those values in the RECAT 1.5 and RECAT EU classification ranges, and can further be satisfied for the study requirements of RECAT.
