摘　　要：在北航D4风洞已研制的机翼摇滚运动/流动研究组合装置的基础上,为实现在一次实验中同步测量机翼摇滚运动角位移和相应的物面压力分布及空间流动参数,发展了机翼摇滚/PIV/物面压力分布同步测控技术。基于该同步测控技术,进一步研究了前体涡诱导机翼摇滚过程中流动特性及演化规律。此外,还对同步PIV技术中粒子材料的选用进行了研究。In order to obtain roll angle displacements/surface pressure and spatial flow structure during the wing rock of model synchronously, a synchronous measurement and control technique of wing rock/PIV/ dynamic pressure was developed on the basis of the combined apparatus applied to study the motion and flow of wing rock in D4 wind tunnel in Beijing University of Aeronautics and Astronautics. Based on this synchronous technique, the flow characteristics and evolution of wing rock induced by the forebody vortex was further carried out to study. Moreover, selection of PIV（Particle Image Velocimetry） tracer particles in the PIV synchronous test was conducted to investigate.
