| 摘 要： | 根据TYC－1涂层材料在加热过程中所出现的物理化学变化，提出了三层物理模型，建立了相应的守恒方程和边界条件，并给出具有空间和时间二阶精度的差分离散公式，并按稳态和轨道模拟二类试验工况，预测了TYC－1防热涂层的内部温度分布，且与测量结果符合很好。

| Abstract: | According to the physical chemical variation due to aeroheating for TYC 1 coating material, a three layer physical module was presented, in which conservation equation and boundary conditions were established and differential discrete equations with second order accuracy were given. Inner temperature distribution for TYC 1 coating material in stability and trajectory ARC tests condition were predicted.Calculated results agreed with the measurement results. |
