摘　　要：简要说明了大型飞机减阻的重要意义,对国内外大型飞机计算流体动力学(CFD)和风洞实验等阻力预示技术进行了初步的评估和分析,重点论述了大型飞机减阻气动布局及装置、减低诱导阻力方法和减低摩阻方法的研究现状和发展趋势,指出中国需要进一步提高CFD和风洞实验阻力预示技术水平,同时加强对气动布局、优化设计以及流动控制等基础科学技术问题的研究．对中国发展大型飞机能起到借鉴和参考的作用．In this paper, the significance of the drag reduction for civil transportation aircraft is briefly illustrated. Drag prediction techniques for civil transportation aircraft, including Computational Fluid Dynamics （CFD） tools and wind tunnel experiments, are analyzed and evaluated. Then the review is focused on the present state and perspectives of the research on drag reduction techniques, specifically in the fields of drag reduction aerodynamic configurations and devices, induced drag reduction methods and friction drag reduction methods. The related fundamental scientific and technological problems of drag reduction, such as aerodynamic configuration layout, optimization design and flow control, as well as the further improvement in CFD and wind tunnel experiment techniques for drag prediction are discussed, in the light of the development of civil transportation aircraft in China.
