摘 要: | 介绍了高温热管在热防护中的应用原理,并利用电弧加热风洞产生的高温、高速气流,模拟高超声速飞行器高温区的气动加热环境,对一种装有高温热管的简单的球柱形原理性模型进行了加热试验。利用高温红外测温装置对模型表面的温度进行了测量,通过与普通复合材料制成的模型试验结构的对比分析,发现高温热管能够有效地将模型高温区热量传导到低温区,装有高温热管模型的驻点温度明显降低,显示出了良好的防热效果。

Abstract: | This experiment study on the application ot high temperature neat-pipe to the thermal protection was carried out in CAAA. With the arc heated wind tunnel, the high tempera ture, supersonic flow field was created. A principle thermal protection model with a high temperature heat-pipe in it was heated; the surface temperature distribution was measured by an infrared temperature instrument, contrast to general composite material model, and the stagnation point temperature reduced distinctly. We found the high temperature heat-pipe transfer the heat effectively from the high temperature field to the lower field, and the thermal protection performance was showed. |
