Research Progress on Magnetohydrodynamic Flow Control Technology for Hypervelocity Reentry Vehicles

The application development of magnetohydrodynamic(MHD) control technology in hypervelocity reentry scenarios is systematically analyzed. The primary application modes of MHD in high-enthalpy re-entry flow field control are elaborated, encompassing thermal protection systems, electromagnetic communication, and airborne power generation, with corresponding modeling methodologies detailed. Key influencing factors affecting MHD control efficacy are identified through analysis across these three application domains. Furthermore, the current experimental research status of MHD control in high-enthalpy flow fields, both domestically and internationally, is critically reviewed, and future development trajectories are discussed. It is proposed that MHD control methodologies should be further expanded in re-entry vehicle applications, necessitating the development of fully coupled computational models and efficient algorithms for thermally ionized plasmas and non-equilibrium flow fields. Verification experiments are recommended to validate these advancements, thereby providing scientific guidance for engineering implementations.
