摘要：为降低翼型的气动噪声，以某型电动水上飞机螺旋桨所使用的 RAF-6 翼型为研究对象，首先通过
CFD/FW-H 方法计算得到翼型的升、阻力系数以及气动噪声；其次使用型函数线性叠加描述翼型的几何形状；
进而，为使翼型获得设计状态下较好的声学与气动性能，由翼型的气动噪声与升阻比构成优化目标，以型函数
系数为变量，以保证翼型升、阻力系数变化不超过 10% 为约束，使用引入响应面模型的遗传算法对翼型进行降
噪优化。通过优化翼型与基准翼型的对比可知，设计状态的优化翼型气动噪声声压级降低了 2.17 dB，升阻比
提高 1.12%，且优化翼型在小攻角状态下具有较为优异的声学与气动性能。优化结果表明，该优化方法具有一
定应用价值，可为螺旋桨噪声控制研究提供参考。

Abstract: In order to reduce the aerodynamic noise of airfoil, the RAF-6 airfoil used bythe propeller of an
electric seaplane was taken as the research object. Firstly, the lift and drag coefficients and aerodynamic noise
of the airfoil were calculated by CFD/FW-H method. Secondly, the geometric shape of airfoil was described
by linear superposition of shape functions. Furthermore, in order to obtain better acoustic and aerodynamic
performance of the airfoil in the design condition, the genetic algorithm which introduced the response surface
model was used to optimize the noise of the airfoil. In the optimization, the objective was constituted by
aerodynamic noise and lift-drag ratio of the airfoil, the coefficients of the shape function were taken as the
variables, and the variation of lift and drag coefficients was not more than 10% as the constraint. By comparing
the optimized airfoil with the reference airfoil, it can be seen that the aerodynamic noise sound pressure level
of the optimized airfoil in the design condition is reduced by 2.17 dB, and the lift-drag ratio is increased by
1.12%. Moreover, the optimized airfoil has excellent acoustic and aerodynamic performance at small angles
