When a SSTO is flying in hypersonic, the thermal protection comes to a key issue. The reliable data of a heat flux in a cavity which is used in design don't exist. In this study, the distribution of the heat flux in a cavity is experimentally investigated by coaxial thermocouples at a hypersonic speed (M_∞=8.1). In the case of the cavity without a step, the flow field is "Open Cavity". In this case, a circulation region is formed in the cavity. However, in the case of the cavity with a step, it is found from the results that two circulation regions are formed in the cavity and the heat flux distribution is different from that of the cavity without a step.
