在低速实验中，应用激光片光源和ＣＣＤ 摄像系统，对一装有“前端襟翼”和“前缘襟翼”的双襟翼７４°后掠三角翼进行实时记录与流态显示的试验技术和图像的三维重建。在迎角０°～５０°范围内，对双襟翼的偏角作不同匹配，研究机翼在定常和非定常的俯仰与滚转运动中出现的旋涡流态，以了解分离涡系发展、破裂和相互作用的演变，物理机理和双襟翼的控涡效果，并对所有显示图像进行分析
In the low-speed experiment, a real-time recording and flow test technology of double flaps 74 ° swept delta wing equipped with “front flaps” and “leading flaps” using laser light source and CCD camera system And 3D reconstruction of the image. In the range of 0 ° ~ 50 ° angle of attack, the divergence angles of the double-flap are differently matched. The vortices flowing in the steady and unsteady pitching and rolling motions are studied to understand the development of the separation vortex, The evolution of fracture and interaction, the physical mechanism and the control vortex effect of double flaps, and analyze all displayed images
