My research program is aimed at enhancing fundamental understanding of magnetohydrodynamic (MHD) interaction for aerospace plasmas encountered during hypersonic flight, or magnetoaerodynamics. Utilizing a magnetic field applied from within a vehicle, these MHD interactions can generate both energy and forces that can be utilized for applications such as hypersonic thermal protection and trajectory control. MHD interactions directly impact U.S. competitiveness (hypersonics superiority), economics (expanded hypersonics facilities), and energy security (MHD and nuclear fusion plasmas). However, fundamental aspects of plasma formation and transport properties in these hypersonic regimes are not well-understood and validated, particularly in the presence of external magnetic fields. For typical hypersonic flight profiles, the potential for MHD interactions is strongest at higher altitudes with lower pressures than those for which aerodynamic forces and heating are strongest. Current high-enthalpy hypersonic plasma facilities are aimed at studying aerodynamic heating and do not simulate the most magnetoaerodynamically-relevant flow conditions. At the University of Colorado Boulder in my Magnetoaerodynamics and Aerospace Plasmas Laboratory (CU-MAPLAB), a unique Inductively Coupled Plasma (ICP) Wind-Tunnel Facility has been developed and established, enabling us to experimentally investigate these magnetoaerodynamic effects and other hypersonic relevant testing applications.
