Engineering Simulation Method for Airfield over Complex Terrain at Minimum Altitude

To describe the exterior environment where airplanes fly at low altitude, complex landform for minimum altitude flying was formed by planning multiple mountain ranges and many kinds of physiognomies. On the basis of potential flow theory, an engineering numerical simulation model was set up to simulate the complex landform and the airfield over it. The results of a digital simulation example showed that the method is applicable for analyzing the dynamics and track characters of an airplane flying at minimum altitude.
