摘要
将基于实数编码的遗传算法与能准确描述翼型粘性流动的NS方程以及旋翼气动分析模型结合起来,以旋翼最大悬停效率作为优化设计的目标对旋转机翼飞机的机翼进行优化设计,设计结果表明通过优化设计旋翼的气动性能得到了提高,达到了优化设计的目的,旋翼优化设计方法是可行的。
Based on the characters of the genetic algorithm with real encoding, a CFD optimization method and rotor wing aerodynamic analysis tools are used in aerodynamic optimization design. The maximum hovering efficiency of rotor wing is selected as the design objective. Design results show that the value of the design objective and aerodynamic function are improved, achieving the demand of the optimization design.
