摘　　要：低空风切变严重影响航空器进离场安全,采用模拟飞行系统方案可以分析低空风切变对航空器起飞与降落的影响,对空器穿越风暴区域的安全规避航策略制定具有重要意义。系统利用Fluent软件进行低空风切变区域的风速场模拟,并以开源飞行模拟器Flight Gear作为航空器仿真平台。系统利用Flight Gear的UDP(User Datagram Protocol)接口引入风场数据,研究风切变区域对航空器飞行状态的影响。模拟系统可以方便地模拟不同航空器在起飞与降落过程中穿越风切变区域的情况,也可以进行比较、分析不同强度风暴核对飞行安全的影响。Low-level wind shear seriously affects the safety of approach and departure of flights, the flight simulation system is utilized for analyzing low-level wind shear influences on aircraft take-off and landing, which is of great significance for seeking the safety circumvention strategy of aircraft crossing the core of the storm. With software, Fluent, the system simulated the regional wind field of low-level wind shear, and utilized the open source flight simulator, Flight Gear, as the aircraft simulation platform. The system sent the wind speed data as the input of system via UDP（User Datagram Protocol） interface and the influences on aircraft flight state was analyzed under the wind shear region. The simulation system can easily simulate the different aircrafts taking off and landing process through wind shear zone, and can also compare and analyze the influences of different intensity storms on the flight safety.
