本文通过风洞试验和水洞试验研究了７５°／４５°双三角翼的外翼前缘形状对大迎角分离流动的影响。试验表明，在涡破裂沿翼面向前发展的迎角范围内，外翼前缘钝化对涡态的发展、压强分布和气动力有较大影响。
In this paper, the influence of the shape of the outer leading edge of the 75 ° / 45 ° double delta wing on the separation flow at high angle of attack is studied by wind tunnel test and water hole test. The experimental results show that the passivation of the outer wing leading to the development of vortex, the pressure distribution and the aerodynamic force have a great influence on the angle of attack along the vortex rupture.
