摘要:
为了分析现行尾流间隔的安全性,建立了尾涡安全评估模型,基于国内现行尾流间隔标准,对诱导滚转力矩系数和所需滚转角速度计算数据进行统计,选择所需滚转角速度作为安全性衡量指标。计算分析了气象条件尾涡遭遇严重度的影响,对不同机型类别组合下的所需滚转角速度计算数据进行统计分析。研究结果表明:与滚转力矩系数相比,所需滚转角速度更适合作为尾流安全性的衡量指标;在顶风条件下可适度缩减所需的尾流间隔,提高空管运行效率;不同类别组合下的当量均值可以反映不同类别组合下的安全程度和潜在的间隔缩减潜力,当量标准值则可反映类别中所属机型之间的差异性。
Abstract:
In order to analyze the safety of current wake separation, a safety assessment model of wake vortex was established. Based on the current standard of wake separation, the statistics of induced rolling moment coefficient and required rolling angular velocity were carred out, and the required rolling angular velocity was taken as the measurement index of safety. The influence of the meteorological conditions on the severity of wake vortex was calculated and analyzed, and the statistical analysis was carried out on the calculation data of required rolling angular velocity under different combinations of aircraft type categories. The results showed that compared with the rolling moment coefficient, the required rolling angular velocity was more suitable as the measurement index of wake safety. The required wake separation could be reduced moderately under the headwind condition to improve the operational efficiency of air traffic control. The equivalent mean values under different combinations of categories could reflect the safety degree and the potential reduction capacity of separation under different combinations of categories, while the equivalent standard values could reflect the difference between various aircraft types in a given category.
