In this paper , the boundary layer characteristics of a supercritical airfoil is researched in wind tunnel . from the start to control boundary layer separation and to improve aerodynamics characteristics of this airfoil , three kinds of trapezoid , delta and airfoil shaped vortex generators are designed based on traditional , sub boundary layer and micro - vortex generators conceptual design . it include as follows : 1 研究工作中,從控制該翼型附面層分離、提高大迎角氣動(dòng)性能的角度出發(fā),通過(guò)風(fēng)洞實(shí)驗(yàn)研究,研究了該翼型的附面層特性和氣動(dòng)性能,針對(duì)其附面層特性,給出了梯形、三角形和翼型式三種渦流發(fā)生器設(shè)計(jì)方案,為下一步研究工作奠定了堅(jiān)實(shí)基礎(chǔ)。
