| 摘 要： | 进行了基于响应面优化方法的低速翼型多点／多目标多约束设计方法研究。分析了完全二阶多项式模型（完全模型）和不含二阶交叉项的多项式模型（简化模型）对优化的影响，并分别进行了单目标和多目标的优化设计。结果表明多目标优化可以改善单目标设计的翼型性能在设计点附近取得极值的局限，而且用简化模型进行的更多设计变量的设计结果要优于完整模型的设计结果。

| Abstract: | An aerodynamic design method for low- speed airfoils is developed which couples RANS （ Reynolds- Aver- aged Navier- Stokes） code and Response Surface Methodology （RSM） to find an airfoil geometry with improved aerodynamic performance at single or multiple design-objectives while maintaining other aerodynamic and geometric constraints. The design cases shows that reduced model without second- order cross items with more design variables can ob- tain better design results than full quadratic polynomials model, and multi- objective design improves the off- design performance in single- objective design. |
