| 摘 要： | 与风暴相关的微下击暴流现象会产生一股类似于从空中指向地面的喷流。为了高逼真的模拟飞机在扰动风场的飞行并对危险状态进行告警，研究了大型飞机在遭遇微下击暴流风切变的实时仿真。基于涡环原理建立了三维微下击暴流模型。以典型民用大型客机建模数据和风切变模型为核心，生成低空风切变探测所需要的数据。基于FAA的危害因子法进行检测并在飞机穿越风切变时及时给出提示与告警信息。整个模型可以在飞行模拟器的实时仿真中运行。

| Abstract: | The “micro-downburst” associated with thunderstorm produces a flow similar to one from the air point to the ground. For hi-fi simulation of airplane flying in the disturbance of wind field and issuance of warning alerts, real-time simulation of large aircraft under wind shear is studied. A three-dimensional microburst model is built up on the basis of vortex ring principle. As the core of the modeling data of a certain airplane and wind shear model, the data of low-level wind shear are generated. The detection is conducted on the baisis of FAA harzard factors. Cautions and warning alerts would be provided in time when the plane flies through the wind shear. The model can be used for real-time simulation in a flight simulator. |
