本文应用流动显示技术对矢量差动喷流情况下 6 0°三角翼前缘涡破裂特性进行了实验研究 ,结果表明 :矢量差动喷流可以有效地控制前缘涡的破裂位置 ,且整个流场主要受喷流速度大的喷流的影响 ,该侧前缘涡的破裂位置随喷流速度的增大向下游发展 ,而另一侧前缘涡的破裂则提前发生 ;另外 ,在喷流速度差一定的情况下 ,喷流速度越小 ,对前缘涡的控制作用越明显 .
In this paper, the vortex rupture characteristics of the leading edge of a 60 ° delta wing under the condition of a vectorial differential jet flow are experimentally studied using the flow display technology. The results show that the vector differential jet can effectively control the rupture position of the leading edge vortex and the entire flow The main field is affected by the jet flow with large jet velocity. The rupture position of the leading edge vortex develops downstream with the increase of jet velocity, while the rupture of the leading edge vortex occurs on the other side in advance. In addition, In the case of a certain speed difference, the smaller the jet velocity is, the more obvious the control action on the leading edge vortex will be.
