The onset and effects of plume-induced boundary-layer separation on the afterbody during powered supersonic flight were investigated. Plume-induced separation occurs for configurations designed for overall drag reduction since boattailing, base bleed, nozzle exit angle, and nozzle extension tend to increase significantly the base pressure. However, each configuration and set of operating conditions must be studied. The purpose of this report is to present only a brief summary of the investigation and to reference the publications which contain the details.
