| 摘 要： | 在高原山地环境中，气流风场的复杂变化对直升机的飞行安全有重要影响，创建高原山区环境下的风场模型，对模拟直升机在高原环境下飞行尤为关键。通过收集、分析已有的高原环境气候数据，建立给定区域的三维空间几何模型，采用计算流体力学方法模拟出给定区域的风场布局，并开发实时插值程序，为风场实时再现提供数据样本。

| Abstract: | In plateau mountainous environment, the complex change of wind field has great influ- ence on the aviation safety for helicopter. Therefore, it is important to establish the near-earth wind field model for simulating helicopter＇s aviation in this environment. In this paper, climatic data of plateau environment has been collected and analyzed to establish the three-dimensional spatial geo- metric model of a given area. With the help of computational fluid dynamics method, the reasonable wind field overall arrangement of the designated area was simulated, and also develop a reahime code to interpolate in a 3-D space, extracting a wind signal representation in the whole wind field to the helicopter flight simulation. |
