| 摘 要： | 对具有襟翼不同缝道构形的多段翼型进行了翼面边界层、表面压力、尾迹速度的测量,同时作了翼面流谱观察实验。实验结果表明,襟翼缝道的不同构形对多段翼型的流动特性、增升效果和升阻特性有着强烈的影响,该研究中具有最佳优化缝道的多段翼型的最大升力系数可达3.360,它为普通缝道多段翼型对应迎角下升力系数的115％。

| Abstract: | Boundary-layer, surface pressure, wake velocity measurements and flow visualization are tested for different configurations of multi-element airfoil. The experimental results indicate that the effects of different flap gap configurations on multi-element airfoil flow characters, lift augmentation effect and lift-drag characters are very strong.This investigations show that lift coefficient of multi-element with optimum flap gap is 3 .360, which is 115% of conventional flap gap multi-element airfoil at the same angle-of-attack. |

| Keywords: | multi-element airfoil flap gap boundary-layer pressure measurement aerodynamic character |
