| 摘 要： | 本文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,对一种装有高温热管的简单球头圆柱体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的试验对比分析,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 paper introduces the experimental study on the application of high temperature heat-pipe to the thermal protection. With the arc-heated wind tunnel,the high temperature,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. In contrast to general composite material model,the stagnation temperature reduced distinctly. We find that the high temperat... |
