| 摘 要： | 为提高多段翼型增升效能,开展襟翼外形和缝道参数同时优化设计研究。优化算法采用遗传算法,以求解RANS方程为气动特性分析方法,通过椭圆方程控制生成多段翼型外形,同时优化缝宽、搭接量、襟翼偏角等位置参数和襟翼外形控制参数,实现多段翼型优化设计。设计实践表明,与只优化位置参数相比,同时优化襟翼外形和位置参数得到的多段翼型有更大的升力系数,方法是可行的,具有一定的工程应用前景。

| Abstract: | The purpose is to enhance the aerodynamic performance of multi-element airfoil by searching for optimal shape and setting parameters .The procedure is driven by a genetic algorithm coupled with a RANS equations solver .Elliptic equations are used to automatically generate the multi-element airfoil shape,some design variables such as gap ,overlap,flap deflection and control parameters of flap shape are optimized to get excellent aerodynamic characteristic .Compared with the result that position parameters are only optimized ,multi-element airfoil optimized by the present method has higher lift coefficient . |
