摘　　要：为描述飞机在低空突防时的外部环境 ,用多重山脉和多种地貌设计构造了飞机超低空飞行时的复杂地形 ,同时 ,基于位势流动理论建立了复杂地形及其上空风场的工程化仿真模型 ,并进行了算例仿真和分析 .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 show that the method is applicable for analyzing the dynamics and track characters of an airplane flying at minimum altitude.
