The possibility of enhancing the MHD control of scramjet inlets by applying glow discharge plasma (GDP) is discussed. The sample results of an analysis are present, which shows that MHD and GDP can be applied in a complementary fashion to further enhance the benefits that could be gained by applying MHD or GDP alone in the inlet duct. This is due to the effectiveness of MHD and GDP vary with the local flow conditions. The local benefit of each action varies from region to region in the inlet flow, and the optimum location for GDP application is different than that for MHD for a given set of local flow parameters.
