Abstract

In view of the technical bottlenecks of eutectic salt electric superheat detector used in aircraft duct leakage monitoring, such as poor electromagnetic compatibility, low measurement accuracy and slow response time, a linear fiber optical sensor for aircraft duct leakage detection is studied in this paper. The research demonstrates that the sensor is capable of adapting to the operational conditions of pipeline bending assembly, with a temperature sensing accuracy of 0.1m, positioning accuracy of 1m, temperature measurement accuracy within ±3℃, and a working temperature range from 0- 180℃. Moreover, it can replace the eutectic salt leak detection sensors to achieve remote distributed measurement.
