| 摘 要： | 使用解析形状函数法表示翼型,将求解绕翼型流场的N-S方程解与遗传算法相结合,可用于高空长航时无人机翼型的设计.设计实践表明,设计的新翼型满足设计要求,且获得比原始翼型高得多的升阻比,采用的翼型设计方法是正确和有效的.

| Abstract: | The combination of N-S equation flow solver with a genetic algorithm optimization method is used to design a new airfoil with high ratio of lift over drag.Airfoil shapes in design process are represented by methods of analytic shape function.Numerical results show that designed airfoils meet the assigned requirements and have higher ratio of lift over drag than that of the initial ones.The airfoil design method is effective and robust. |
