“…This method describes the plasma motion in the form of fluid, which has been adopted by many researchers. Among them, LI calculated the thermal protection effect of aircraft under complex magnetic field through MHD equations and compared it with OREX (Li et al 2017b). The calculated results are in good agreement with the experiment.…”

“…In the past 20 years, magnetic control technology has been supplemented by experiments and simulations, and the research on magnetic control technology has also expanded to other aspects. The research contents include magnetic interaction model (Lineberry et al 2002, Bityurin et al 2004a, Shneider and Macheret 2005, Bityurin and Bocharov 2006, Nagata et al 2013, magnetic field type (Li et al 2017a, Yao et al 2018, re-entry orbit (Shimosawa andFujino 2016, Fujino andTakahashi 2022), simulation (Poggie and Gaitonde 2002, Fujino et al 2003, Bityurin et al 2005, Katsurayama et al 2008, Shimosawa and Fujino 2016, Li et al 2017b, experiment (Bityurin et al 2004b, Smith et al 2018, Lefevre et al 2021 and concept (Bisek et al 2013, Balasubramanian et al 2016.

The study of plasma flow under the thermal protection magnetic field of reentry vehicle is helpful to verify the magnetic control thermal protection technology and further understand its flow law. By solving hypersonic magnetohydrodynamics equations and combining with dipole magnetic field conditions, the plasma flow mechanism of RAM-CII (Radio Attenuation Measurement Experiment) spacecraft at 61km altitude is analyzed and compared with OREX (Orbital Reentry Experiment) spacecraft under the same conditions. The results show that the plasma flow of RAM-CII is more complex than that of OREX, and there are several regions with different Lorentz force directions near the aircraft, which play the role of plasma ejection and adsorption. Under the action of Lorentz force, the side flow of the aircraft will be separated and reattached, and the fluid stagnation zone will be generated. The results show that for different shapes of aircraft, the flow laws caused by magnetic thermal protection technology are different, and the side flow may be greatly affected.

“…Numerical simulations of MHD heatshield are also presented in [11,[23][24][25] . More recently, Li et al n [26] have investigated the effect of Hall parameters on MHD heatshield, showing that such an effect is an important factor limiting the applied magnetic induction strengths for the implementation of the concept. In particular, a strong Hall effect (that would exist for high altitudes and strong magnetic fields) can actually diminish the increase in shock standoff distance.…”
