研究了民用客机机翼设计中的环量分布设计规律。建立了一种以航程为系统级优化目标，融合气动与结构两个学科作为子学科的多学科NAND （Nested Analysis and Design）优化系统。通过合理的简化模型，有效地研究了机翼展向环量分布对结构重量、升阻比和航程这3方面的影响，找到了一种合理的适用于亚声速单通道民用客机的机翼环量分布。利用航程最远环量分布与椭圆形环量分布分别设计一副机翼并进行对比验证，结果表明：使用设计环量分布的机翼较椭圆形环量分布机翼增加了近5%的阻力，但由于结构减重使航程增加了近100 km。在机翼设计过程中阻力最小对全机性能来讲可能并非全局最优，将气动压心合理内移会使全机经济性有所提高。

This paper deals with the design rule of commercial aircraft circulation distribution by establishing a NAND (Nested Analysis and Design) formulation. The approach incorporates an aero-structural analysis solver. A method is developed to estimate the wing weight based on fundamental structural principles. The aerodynamic solver is based on the full potential equation with viscosity modification. In order to find the most economical aerodynamic circulation distribution for a commercial aircraft this paper uses range as the object for this formulation. Finally an aerodynamic circulation distribution is found which enhances the aerodynamic resistance and flight distance respectively by 5% and 100 km. The conclusion is made that although elliptical circulation is best for aerodynamic characteristics, it may not be the best for civil aircraft design because of increasing structure weight.This conclusion can serve as a reference during civil aircraft wing design.
