机场航站楼设计影响机场附近区域风场结构,在大风条件下,不同区域飞机停放稳定性受建筑绕流影响,差别较大.为了定性定量地评估不同停机位的飞机停放稳定性,本文采用数值分析方法,对航站楼和飞机进行3D建模,使用商用软件进行CFD数值仿真.基于大气边界层理论,设置来流条件,进行机场不同区域飞机停放模型的数值仿真,得到不同模型的气动特性,然后进行详细分析,得到飞机气动特性的影响规律以及稳定性较低的位置域.结合飞机受力和流场分布,详细分析其气动力和气动力矩变化的机理.最终得出可以指导机场规划和管理的一般性结论.
Numerical Analysis of Wind Field Influence on Aerodynamic Characteristics of Parked Aircraft near Buildings
The configuration of terminal affects the wind field structure in the surrounding area of the airport.Under strong wind condition,the stability of parked aircraft in different areas is significantly different as it is influenced by the flow around buildings.In order to conduct qualitative and quantitative analysis of the stability of aircraft parking at different stands,this paper uses numerical analysis methods to study the terminal and aircraft flow field characteristics.Based on the theory of atmospheric boundary layer,the inflow conditions are set,and numerical simulations of parked aircraft models in different areas of the airport are carried out to obtain the aerodynamic characteristics of different aircraft models.Then,detailed analysis is conducted to obtain the rules of the aircraft aerodynamic characteristics change and the location with low stability.And then the mechanism of generation in aerodynamic force is analyzed in detail based on forces and flow field distribution.Finally,the general conclusion is drawn that can guide airport planning and management.
