| Abstract: | On the basis of the theory of flow over sphere,this paper sets up an engineering simulation method to simulate 3-D wind field over complex terrain at low altitude,and designs a complex landform to describe the terrain where airplanes fly at low altitude.It implements simulation and analysis by some cases.The digital simulation results shows that the method can be used to provide the 3-D wind field at low altitude and is applicable for analyzing the dynamics characters of flights at low altitude. |
