The results indicate that the thickness variations exhibit no significant influence on stagnationtemperature, while the cooling power drops sharply as the thickness increases.
计算结果表明：驻点温度随热防护层厚度的变化并不明显，而冷却系统功率随热防护层厚度增加急剧降低；

In the model the exit area ratio, solid particle mass ratio, fuel enthalpy of combustion, jet gas molecular weight, chamber stagnationtemperature, flight Math number etc. have been considered.
The temperature profiles measured from the boundary layers at stagnation-point are reasonable in agreement with the results of theoretical calculation.
