Shockwaves form when an aircraft flies and passes the speed of sound. This effect can be seen sometimes in the humid air around an aircraft, or in a high-speed wind tunnel around a model airplane. Each case concerns a big operation and it is quite hard to visualize. Here, we explore the possibility to visualize the shockwaves around an airfoil in a flowing soap film. In our quasi-two-dimentional flow of soap film, shockwaves indeed becomes visible as the flow speed exceeds the speed of waves that propagate on the elastic film. We will use such shockwave patterns to compare with that obtained from wind-tunnel experiments.
