Store Separations from a Supersonic Cone
The purpose of this research was to analyze the environment a store would travel through if ejected from a supersonic cone. This was done using the Beggar Computational Fluid Dynamics (CFD) code from the Air Force SEEK Eagle Office at Eglin Air Force Base, FL. CFD simulations were compared to experimental results from a previous AFIT thesis and conclusions were drawn based on whether or not the current wind tunnel setup at AFIT is capable of performing analyses of supersonic store separations. Also included in this research is a study of supersonic base pressure profiles, near-wake velocity profiles, wind tunnel shock interactions and force/moment studies on a conical store and parent vehicle. This thesis provided the ground work for future CFD studies relating to aft supersonic store separations. Eventually, this research will be used as the basis of dynamic store separations using the Beggar code. Once dynamic separations are possible, store trajectories and ejection forces can be studied in more detail for a number of different flight conditions.
