摘　　要：利用遗传算法进行了低雷诺数高升力翼型的气动优化设计,并利用风洞实验检查了设计的正确性。优化后的翼型其气动特性有明显改善,这说明了利用遗传算法进行低雷诺数翼型气动优化的可行性。风洞实验结果验证了优化设计方法的正确性,同时也表明新设计翼型有较高的升力系数和相对大的升阻比,其升阻比提高了10%。The paper expresses aerodynamic optimization design of lower Reynold number high-lift airfoils using genetic algorithm, wind-tunnel experimental of design airfoil tests correctness of design. Optimized airfoils have a considerable improvement on aerodynamic performance. It shows the feasibility of genetic algorithm applied on aerodynamic optimization design. The wind tunnel test results indicates the correctness of optimization algorithm. The performance of design airfoil was greatly improved at both lift coefficient and lift-to-drag ratio. The lift-to-drag ratio can be increased by 10 percent relative to the well-known LA203A airfoil.
