摘　　要：本文采用Kriging代理模型,在基准翼型基础上,采用网格变形技术和CFD方法获得样本数据,以不同马赫数的升力系数、阻力系数等气动特性要求为优化设计目标,以厚度分布为约束,进行了多目标多约束的低速翼型优化设计研究,获得了满足目标特性要求的低速翼型。采用该翼型设计机翼,并随全机进行了风洞试验验证,结果表明采用优化设计的翼型构造的机翼,满足了全机设计要求。In this paper,the Kriging agent model is used, on the basis of the reference airfoil,the mesh deformation technology and CFD are used to obtain sample data,and the aerodynamic characteristics such as lift coefficient and drag coefficient of different Mach numbers are used as the optimization design target,and the thickness distribution is used as the constraint,and the multi-objective and multi-constraint low-speed airfoil optimization design is studied,and the low-speed airfoil that meets the target characteristic requirements is obtained.The wings was designed with this airfoil,and the wind tunnel test verification was carried out with the whole aircraft,and the results showed that the wings designed with the optimized airfoil met the design requirements of the whole aircraft.
