摘要
飞机减阻是当今研究的热点问题,其中诱导阻力减小更是被广泛关注的重点。本文通过国际上通用CFD软件FLUENT分别对平直三维机翼与加装优化设计翼尖小翼的三维机翼进行模拟计算,并对比计算结果,分析翼尖小翼的减阻效果。
The study of drag reduction in the flight is focused on the drag of lift induced,which is given extensive attention currently.In this paper,the numerical simulation is studied on the airfoils of without and with winglet respectively,and then the results are compared.Finally,the effect of drag reduction of the winglet is analyzed.
