• An experimental program has been undertaken to simulate the impingement of an under-expanded supersonic jet, resulting from the failure of the wall of an aero-engine combustion chamber, onto an adjacent surface. Experiments were performed for a range of nozzle pressure ratios from 10 to 60 for an axisymmetric sonic nozzle and a rectangular sonic nozzle. The impingement plate was placed 17 nozzle exit diameters downstream. Schlieren images of the flow structure are presented and discussed. In the case of the rectangular nozzle, flow field asymmetry is observed to persist well downstream of the nozzle exit to the point of impingement.
