中文摘要：

通过低速风洞实验研究了Gurney襟翼对双三角翼气动特性的影响,结果表明Gurney襟翼可以提高双三角翼的升力系数、最大升力系数以及中高升力系数情况下的升阻比。此外,进一步证实了Gurney襟翼的有效迎风面积是影响增升效果的主要因素。

英文摘要：

The effect of Gumey flap on double delta wing aerodynamics was conducted in low speed wind tunnel, the experimental results indicated that Gumey flap can promote the model＇s lift coefficient, maximum lift coefficient and lift-todrag ratio at middle to high lift coefficient. Moreover, it was farther verified that the effective windward area of Gumey flap is the most important parameter for its lift-enhancement.
