| 摘 要： | 采用Hicks-Henne方法参数化翼型,以巡航升阻比、低速最大升力系数为目标进行优化设计.利用试验设计方法对总体设计空间内目标函数的分布进行初步评估,得到目标函数的初始Pareto前沿面,以前沿面上的点为基准,把总体设计空间分割成独立的局部设计空间进行并行寻优,逐步更新直至得到收敛的Pareto前沿面.对前沿面上的典... |

| Abstract: | Hicks-Henne method was used to parameterize a supercritical airfoil,and cruise lift drag ratio(L/D) and low speed maximum lift coefficient were used as objectives to be optimized.A primary Pareto front was obtained by using Design of Experiment(DOE) method to give an estimation of objective distribution in the design space.Based on samples on the Pareto front,the global design space was divided into relatively small local design spaces to search the optimum points in parallel to achieve a converged Pareto f... |
