摘要
航空发动机加力燃烧室出口温度较高,采用红外辐射吸收测量可以克服传统热电偶测量的缺点。利用红外光谱的某一强辐射吸收谱带的特点,设计了一套红外测温仪光学系统,并给出了具体的试验措施和信号采集与处理方法。
The outlet temperature of aero-engine is very high. The method of infrared radiation absorption and its principle and experimental installation is discussed. Using this way the temperature of gas flame was surveyed. The signal acquisition and processing method is also given.
