涡轮后温度现场校准技术研究

Study of in-Situ Calibration Technology of Temperature after Turbine

介绍了航空发动机涡轮后气流温度传感器的现场校准方法,并对被校温度传感器的测温偏差进行了理论计算。结果表明,理论计算的结果与现场校准的结果吻合较好,说明所采用的校准方法是合理的,可以解决航空发动机涡轮后气流温度的准确测量问题。

The in-situ calibration technology of the temperature sensor which is used to measure the flow temperature after the aeroengine turbine is introduced in this paper, and the theoretical calculation about the deviation of temperature measurement of the calibrated sensor has been made. The calculation result tallied well with the calibration result, which proved the calibration method is reasonable, and the problem of measuring flow temperature after aeroengine turbine precisely can be solved.
