| 摘 要： | 为更好的研究尾流的演化和遭遇，将数值模拟与后机响应相结合，进行不同机型组合下的尾流危险区研究。采用H-B(Hallock-Burnhan)模型模拟仿真尾涡流场，进行尾涡演化，提取全流场的时空信息。选取我国数量较多使用频繁的机型进行尾流遭遇分析，将滚转力矩系数作为尾涡遭遇安全评价指标，求解不同前后机的尾流间隔，并进行危险区的可视化。结果显示：不同机型组合下呈现出的尾流间隔相比于RECAT-CN(Re-categorization)尾流间隔都有一定的缩减空间。同前机不同后机的机型组合下，由于后机气动力特性的不同，危险区的差异主要表现为纵向范围大小；不同前机同后机的机型组合下，危险区的宽度和长度的变化都存在一定的差异。使用数值模拟进行前机尾流演化能更好的探究尾涡危险区的变化趋势，更精确的计算尾流间隔。

| Abstract: | To better study the wake turbulence evolution and encounter, numerical simulations are used to combine the leading aircraft with the following aircraft ,and conduct a study of the wake turbulence danger zone under different aircraft combinations. The H-B(Hallock-Burnhan) model is used to simulate the real wake turbulence flow field for wake turbulence evolution and to extract the spatial and temporal information of the full flow field. A large number of frequently used aircrafts in China are selected for wake encounter analysis, and the roll-moment coefficient is used as the safety evaluation index of wake turbulence encounter to solve the wake separation of different leading and following aircrafts and to visualize the danger zone. The results show that the wake separation presented under different aircraft combinations has a certain reduction space compared with the RECAT-CN(Re-categorization) wake separation. The differences of the danger zone is mainly in the longitudinal range due to the different aerodynamic characteristics of the following aircrafts for different combinations of the same leading aircrafts and different following aircrafts; there are some differences in the width and length of the danger zone for combinations with the different leading aircrafts and the same following aircrafts. Using numerical simulation for the wake evolution of the leading aircrafts can better investigate the trend of the wake danger zone and calculate the wake interval more accurately. |
