Abstract
The airblast precursor is a shock refraction effect formed by the interaction of a shock wave with a high-sound-speed layer. Helium was injected through a porous ceramic plate to create such a layer near the wall of a small shock tube. The flow was made visible by shadow, schlieren and interferometer photography. Incident shock Mach numbers of M = 1.7 were used. A prominent feature of the flow is an unstable supersonic wall jet that develops large-scale, turbulent structures.
