The combat aircraft wind tunnel model DLR-F23 produces a multi-vortex system that experiences vortex-shock-, vortex-vortex-interactions and vortex breakdown. The flow topologies change throughout the Mach-number and angle of attack regime of the conducted experiments. The unsteadiness of the flow was investigated on, in order to increase the understanding and capabilities in numerical prediction.
