| Abstract: | Under the background of Aero-engine Direct Thrust Measurement program, the temperature measurement method of thrust pin surface based on RTD(Resistance Temperature Detector)is introduced. The impact of temperature ranging on strain gage bridge output voltage is obtained by temperature experiment. The real temperature of the thrust pin under the condition of engine bench test is scaled. Combining the result of temperature experiment, engine bench test and the previous load calibration, the modification of temperature to the installation thrust force is acquired to indicate the influence of temperature to measurement precision. |
