Abstract

In this study, we tried to conduct time-resolved PSP imaging of sonic-boom phenomena using a high-speed video camera. For this purpose, we visualized sonic-boom passing through a test plate mounted on the inside of the ballistic range by using ultrafast-response PSP and shadowgraph method simultaneously. By combining PSP technique and shadowgraph method, we successfully estimated pitch and yaw angle of free-flight projectile simultaneously. In addition, time-resolved PSP imaging of near-field sonic-boom phenomena using a high-speed video camera was also conducted and flow field was clearly visualized. These visualization results were well agreement compared with pressure profile which was measured by unsteady pressure sensors qualitatively. This means that the qualitative observation of near-field sonic-boom by using PSP technique is available in ballistic experiments.
