摘　　要：航空器的分类与尾流间隔标准是影响机场容量和吞吐量的关键。近年来,一些国家提出并实施了适合本国国情的尾流重新分类(RECAT)。但是,由于缺乏理论支持与优化,这些标准仍显保守。因此,本文重点研究了航空器的分类优化和尾流间隔标准缩减问题,通过尾流环量和滚转力矩建模来研究尾流强度的演化机制,并提出了基于尾流环量的分类方法和安全间隔模型。实验结果表明,与美国和欧洲的RECAT标准相比,本文提出的RECAT-Revise标准在缩减尾流间隔和提高机场容量方面具有更好的效果。The categorization and wake vortex separation standard of aircraft are key elements affecting the capacity and throughput of airport. In recent years, some countries proposed and implemented wake recategorization(RECAT) technology suitable for their own national conditions. However, due to the lack of theoretical support for optimization, these standards are still relatively conservative. This paper focuses on the optimization of aircraft categorization and the reduction of wake vortex separation. The circulation and induced rolling moment of wake vortex are carried out to investigate the wake generation and the influence on the rear aircraft. On this basis, a new categorization method based on circulation and a safe separation model are proposed. In the end, experiments show that the proposed RECAT-Revise standard has better effects on wake separation reduction and airport capacity improvement than RECAT standards of the United States and Europe.
