When we carry out shock reflection experiments over a wedge, it is inevitable that the wedge has a finite "radius of curvature" at its tip. Then the reflection will be truly unsteady at the tip, like the reflection over a circular cylinder. A series of shock reflection experiments has been carried out by the use of shock tube in order to investigate the influence of curvature at the wedge tip. We used two kinds of models; one was a wedge with a curvature at the tip and the other was an ordinary plane smooth wedge. For both cases, the slope of triple point trajectory was almost the same, while the relation between angles of incidence and reflection was different. Within the condition of the present experiment, the influence of curvature at the tip was not conspicuous over the shock transition.
