对再人飞行器再人过程中所经历的流场热一化学状态和过渡控制进行了研究,提出新的局域平衡判据和流场中控制方式的判据。利用这一新的判据,分析了流场中不同区域的化学状态和不同气体组元对烧蚀防热的影响。
The thermal-chemical state and transitional control of the flow field experienced by the reentry aircraft are studied, and new criterion of local equilibrium and control criterion in the flow field are proposed. Using this new criterion, the influence of chemical states of different regions in the flow field and the effect of different gas components on ablation prevention is analyzed.
