为了及时规避危险风场,确保飞行安全,需要向驾驶员和指挥员提供更详细的风场信息。使用多普勒气象雷达的谱宽数据,结合紊流场分布模型,可以对所探测风场的紊流强度进行估计;利用紊流强度完成了符合统计规律的风场数字重建;然后根据飞机飞行参数进行风场飞行仿真,引入振动总量评价指标对所得到的风场响应进行安全性和舒适性评价,最后给出了可视化结果。结果显示,相比于传统谱宽数据,该方法能提供更为易用和准确的风场信息。
In order to avoid dangerous wind fields in a timely manner and ensure flight safety, it is necessary to provide pilots and commanders with more detailed wind farm information. Using the spectral width data of Doppler weather radar and the turbulent flow field distribution model, the turbulence intensity of the wind field can be estimated, the wind field digital reconstruction in accordance with the statistical law can be completed by using the turbulence intensity, Parameters of the wind field flight simulation, the introduction of the total vibration evaluation index of the wind farm response to the safety and comfort evaluation, and finally gives the visualization results. The results show that this method provides more easy-to-use and accurate wind farm information than traditional spectral width data.
