Abstract:In this paper,the significance of the drag reduction for civil transportation aircraft is briefly illus- trated.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 aerody- namic 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.
Keywords:drag reduction  drag prediction  civil transportation aircraft  aerodynamic configuration layout  flow control
