The formation of shock waves behind a symmetrical body was studied in a shock tube. Three models of different afterbody shape were examined: a step, flare and boattail. The initial pressure ratio was set to 200 and optical measurements were made. It is shown that in all cases the reflected shock merges with the secondary shock and develops into the recompression shock. However, in the intermediate stage the recompression shock is unstable and asymmetric with respect to the centerline.
