摘　　要：表面微沟槽等结构能够限制航空器壁面低速区小涡流生成和猝发的相关雷诺应力,从而降低摩擦阻力,而且该方法简单易行、不需额外增加重量,成为航空器减阻的主要途径之一。概述了表面微结构减阻性能尺度效应的研究进展,表明微结构无量纲尺寸在15左右时减阻性能最佳,减阻率为8%左右;着重综述了简单形状微结构、仿生微结构以及大面积微结构等减阻微结构去除、压印以及滚压等制造技术的研究现状,简析了目前仿生减阻微结构制造技术存在的不足;在此基础上,对仿生减阻微结构制造技术的未来发展和应用进行了展望。Surface riblets of aircraft can inhibit the occurrence of turbulent flow and related Reynolds stress, and then decrease skin friction. This method is simple and easily realized, and also does not need extra weight, which becomes a main way for drag reduction of aircraft. In this paper, investigations on size effects of drag reduction were reviewed, and it indicated that the drag reduction property was the best when the dimension of the nondimension was 15, which can obtain drag reduction of about 8%. Then, the authors reviewed the progress of manufacturing technologies, such as removing machining,coining and rolling processes for simple shape micro-structures, bionic microstructures and large area microstructures.Shortages of existing manufacturing technologies were analyzed for bionic microstructures. On the basis, the future development and application of bionic microstructure drag reduction technologies were prospected.
