| 摘 要： | 改进与完善尾流间隔标准是提高终端空域容量,保障终端空域安全运行的重要措施.分析、总结了国内外缩减尾流间隔技术,指出实现尾流间隔缩减的途径有2类,一类是偏置进近程序,着重于后机避开前机的尾流影响区域;另一类是动态尾流预测模型,致力于将前机尾流对后机的影响控制在可容忍的范围之内.通过分析国内外尾流间隔缩减系统的结构组成及应用情况,指出目前研究的热点集中于动态尾流预测.并重点分析了尾流预测与尾流遭遇2个核心模块;通过快速准确地预测尾流的产生与演变,评估尾流的严重性,能够给出安全、合理的尾流间隔.提出未来研究的发展方向.

| Abstract: | Improving tail vortex separation standard is an important measure for increasing the capacity of airport airspace and maintaining its safe operation. Techniques for reducing tail vortex separation both at home and abroad are summarized. Firstly, it is found out that two primary methods have been used to reduce tail vortex separation. One is based on offset approach, which recommends the following aircraft to avoid the affected area by the former aircraft; the other is dynamic tail vortex model, which aims at controlling the impact within a tolerable range. Then, a synthesis and applications of dynamic tail vortex separation reduction systems are presented and it is found out that the dynamic tail vor- tex model is more popular. In addition, tail vortex prediction module and tail vortex encounter module are analyzed. A quick and accurate prediction of tail vortex can be used to assess the impact of tail vortex, which provides a base for calculating a reasonable tail vortex separation. Finally, the future research areas are presented. |
