Supersonic lateral jets are a convenient method for aerodynamic steering of bodies flying at hypersonic speeds. An accurate prediction of the resulting aerodynamic force is difficult, because the flowfield around such a jet in a hypersonic cross-flow is quite complex. In addition to the jet thrust a considerable pressure load on the body earl be generated by the jet/cross-flow interaction. Several flow and configuration parameters have an effect on the flow interaction pressure force. In this study, the influence of the body's boundary layer upstream of the side jet is studied experimentally. A shock tunnel is used to generate a Mach-6-flow around a cone-cylinder model with a side jet. By means of flow visualization and unsteady pressure measurements the flowfield around the side jet is characterized for different conditions.
