摘要

针对树脂基热防护材料烧蚀传热的关键参数分析问题，采用碳化层-热解层-原始材料层一维模型，分析了热防护材料烧蚀热解响应过程的传热特性，得出了不确定参数影响传热过程的敏感性大小，结果表明：材料的热导率对树脂基热防护材料烧蚀传热特性影响最大，密度、比热容和材料厚度影响程度较大，其他参数的影响性可以忽略。同时建立了温度和不确定参数之间的量纲1准则关系式，为热防护材料的选取设计以及模型参数修正提供了参考依据。

Abstract

To analysis the key parameters of ablation heat transfer resin based thermal protection materials

a charring layer-pyrolysis layer-original material layer one-dimensional model is applied

heat transfer process is analyzed

and the uncertain parameters sensitivity of ablative heat response of thermal protection material is obtained. The results show that the thermal conductivity is the greatest impact on the heat transfer characteristics of resin based thermal protection material ablation

the density

specific heat capacity and material thickness are secondary

and the influence of other parameters can be ignored. Meanwhile

the dimensionless correlation between the temperature and the uncertain parameters is established

which provides a reference for the selection

design and parameters correction of the thermal protection materials.
