摘要
用于高焓风洞实验中模型表面温度测量的CCD红外热成像系统 ,测温范围 1 0 0 0～ 350 0K。笔者介绍系统原理和标定过程 ,并给出了初步风洞实验结果。通过与红外高温计测量结果的比较分析 ,验证了该系统的可靠性和实用性。系统的研制成功为地面防热 /热结构实验中模型表面温度测量提供了先进的手段。
A CCD IR thermography system can be used to measure the model surface tempe^ratures up to 3500K.In this paper,the system calibration test and dynamical compare test are introduced.The surface temperatures distribution of the hemispherical and small blunt model in high enthalpy facility are measured by the CCD IR thermography system. The results are compared with that obtained by an infrared pyrometer.It indicats that the developed system is successful and it will play an important role in high enthalpy wind tunnel experiment.
