Not Available Utilizing plasma interactions on hypersonic vehicles for aerodynamic control, drag reduction, thermal management and propulsion are proposed by-US agencies, industry and foreign interests (Russian AJAX). These schemes address the Air Force's need for future hypersonic vehicles. This SBIR will develop a plasma MGD/MHD system designed to enable ' hypersonic propulsion by electromagnetic flow interactions with the inlet capture stream. This system is coined the MGD Inlet' is a non-intrusive means for enhancement of scramjet operation. The MGD inlet is defined from experimental and analytical studies of plasma assisted propulsion concepts. It is conceived for the first generation plasma augmented scramjet to use those interactions considered realizable in the near term. The interactions exploited with this inlet are pre-compression of the capture stream, internal flow compression, and scramjet entrance flowfield conditioning. Phase I will perform R&D for the MHD inlet to refine its design and identify test requirements. Phase I combines analysis of hypersonics and plasma/MGD/MHD phenomena with system engineering and integration to include trade-off and vehicle integration studies. Phase I will evaluate sub-systems for an MHD inlet design for test and evaluation in Phase II. Phase II will produce design criteria for a flight hardware inlet for Phase III.
