摘要：

Micro-packaged fiber Bragg grating temperature sensor is used to perform the distributed temperature sensing for the local area of the object surface. Packaged with steel capillary, ten wavelength-division-multiplexed temperature sensors are cascaded and placed in parallel along the tangential direction at the observed point for making quasi-distributed detection. The response time of the packaged sensors is 2.74 s. Using ANSYS software to analyze the thermal steady-state laminar flow of air the contour plots of temperature distribution was obtained. Experiments show that the first-order change rate of the curves of temperature change with height is -24.262, and the second-order change rate is 10.1172. Comparing with the result of ANSYS simulation (its first-order change rate is -22.842, and second-order change rate is 8.613), the reliability of this measurement method was verified. This technology provides a technical support for knowing the local distribution of temperature as well as a new testing program for aircraft material selecting and configuration determining.
