| 摘 要： | 飞机复杂外形的气动特性数值模拟在飞机型号研制中有重要的作用,也是数值模拟中比较复杂的问题。笔者采用基于Octree技术的方法生成非结构四面体网格,用耦合隐式离散方法进行有限体积离散,利用此方法对某型飞机带外挂和舵面偏转情况的气动特性进行了数值模拟,将计算结果与实验结果作了比较,收到较好效果。

| Abstract: | It is important that the aerodynamics characteristics of a complicated shape is numerically modeled in an aircraft model design and it is very complex problem. auther generate unstructured tetrahedral meshes using the method based on Octree technology and use a coupled implicit approach to disperse the equations according to finite volume.the aerodymics characteristics of a aircraft is modeled with the method in the case with a individual unit and the case with a gauche rudder,the computational results were compared to the test results,the effect is very good. |
