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 synchro-nous technique, the flow characteristics and evolution of wing rock induced by the forebody vortex was fur-ther carried out to study.Moreover, selection of PIV(Particle Image Velocimetry) tracer particles in the PIV synchronous test was conducted to investigate.
