摘要
针对飞机增升装置缝道参数的气动优化问题,设计并搭建了具有嵌套双循环流程的优化平台。设计过程中以敏度分析改进遗传算法,以最大升阻比为优化目标,对二维翼型30P30N进行了缝道参数优化。优化结果表明,翼型的升阻比性能获得了显著提升。该优化平台及优化方法经拓展可用于多种翼型及机翼增升装置的气动优化。
This article constructed an aerodynamic optimization platform oriented to the design of aircraft high lift devices, and use this platform to design the gap parameters of 30P30N three-element airfoil with a nested double cycle worklfow. During the optimization process, the platform use adaptive genetic algorithms improved by sensitivity analysis as its main optimization method. The results indicated that the lift-drag ratio of this airfoil has been signiifcantly improved, and this optimization is suitable for kinds of multi-element airfoils’ high lift devices.
