  1. 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

    給出了該翼型的附面層特性:翼型表面基本為湍流附面層;在靠近附面層分離位置處,速度型形狀、特別是靠近翼型表面的底部速度型形狀變化不定,是湍流流動的隨機性所致;該翼型具有較好的附面層分離形態,但在失速迎角附近,附面層分離形態變化劇烈、失速特性差,是翼型上翼面形狀較為平坦所致。
