Abstract

Thin film thermocouples have high respond speed and measuring accuracy of the dynamic surface temperature for their negligible thermal mass. In this paper, ITO thin film thermocouples were used to capture the transient wall temperature in supersonic combustor. A protective bilayer was used to improve the sensor's thermal stability and durability. Calibration results show that the sensor exhibit high thermal stability over 1600K for 300 minutes. And a relationship was established to describe the thermoelectricity of ITO thin film thermocouples. The dynamic temperature of scramjet's inner wall was successfully captured and the combustion procedure was characterized clearly.
