摘要

研究再入飞行器热保护磁场下的等离子体流动，有助于验证磁控热保护技术，进一步了解其流动规律。通过求解高超音速磁流体力学方程，结合偶极磁场条件，分析了61公里高空无线电衰减测量（RAM）-CII（RAM实验）航天器的等离子体流动机制，并与相同条件下的轨道再入实验（OREX）航天器进行了比较。结果表明，RAM-CII的等离子体流动比OREX更复杂，并且在飞机附近有几个洛伦兹力方向不同的区域，起到等离子体喷射和吸附的作用。在洛伦兹力的作用下，飞机的侧流会分离并重新附着，从而产生流体滞流区。结果表明，对于不同形状的飞机，磁热防护技术引起的流动规律不同，侧流可能会受到很大影响。

Side plasma flow and stagnation of a conical blunt body vehicle under an axial dipole magnetic field

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 radio attenuation measurement (RAM)-CII (RAM Experiment) spacecraft at 61 km altitude is analyzed and compared with orbital reentry experiment (OREX) 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.
