摘　　要：文摘介绍了用于飞船返回舱的低密度材料防热机理及热响应数值模拟方法。采用分层模型建立多层结构一维热传导方程,计算了低密度材料温度分布,并与电弧加热器试验结果作了比较,两者符合较好。The thermal protection mechanism of low-density thermal material and numerical simulation of thermal response for re-entry module are presented. The temperature distribution of low density thermal material was calculated by using one-dimensional thermal conduction equation of muhilager structure built by layered model. The comparison between calculation and test results of ARC heater showed good agreements.
