介绍中国国家大剧院模型表面风荷载的风洞实验结果。首先对它的半椭球表面在大气边界层中的风压分布及增加表面粗糙度的影响进行研究，实验结果表明在不同风向下它的风荷载具有很好的规律性。有环境影响的对比实验结果表明人民大会堂对大剧院的风荷载有较大的影响。 - 3 . the characteristics of boundary layer ' s transition , shape and separation are researched . the details as follows : ( l ) airfoil surface is turbulent boundary layer flows ; ( 2 ) velocity figure changed unsteady near the point of boundary layer separation due to randomicity of turbulent flow ; ( 3 ) the airfoil have better state of boundary layer separation and poor stall characteristics because of the upper surface of airfoil is flat
给出了该翼型的附面层特性：翼型表面基本为湍流附面层；在靠近附面层分离位置处，速度型形状、特别是靠近翼型表面的底部速度型形状变化不定，是湍流流动的随机性所致；该翼型具有较好的附面层分离形态，但在失速迎角附近，附面层分离形态变化剧烈、失速特性差，是翼型上翼面形状较为平坦所致。
