【摘要】 以Isight为集成平台,将遗传算法与CFD计算结合在一起,引入到翼型气动优化设计中。该优化设计方法不仅注重提高升阻比,而且在升力系数达到设计要求的条件下尽可能地减小阻力系数,以及防止绕前缘点力矩系数的剧烈变化。同时考虑到负迎角时的升力系数,可以说是真正的多目标气动优化。计算结果表明,这种优化方法是可行的。更多还原

【Abstract】 Integrated CFD and Genetic Algorithm,Isight is applied to the optimization design for airfoil.Using this approach,the lift-drag ratio is improved,the drag coefficient is reduced as song as possible with the lift coefficient demanded,and the large-scale change of pitching moment coefficient is avoided.The result shows that this approach is viable in Multi-Objective Optimization Design for airfoil.更多还原
