Abstract:
The performance of tip clearance sensor at −196 ℃ was studied. Both static and dynamic tests of the sensor were conducted. A cryogenic cyclic device and a cryogenic rapid temperature drop device were developed to perform the static test of the sensor, including cryogenic cycle, sensor durability and piecewise rapid temperature drop tests. Dynamic test was carried out on a cryogenic compressor platform. The results showed that: effective voltage exported by the sensor was far more than 0.2 V, and the signal-to-noise ratio was better than 26 dB under cryogenic condition. Material, structure and manufacturing process of the sensor satisfied the requirements of multiple temperature cycle alternation, persistent hypothermia and rapid temperature drop in cryogenic situation. Performance of the sensor was stable, and intensity of the laser had no obvious attenuation. Dynamic measurement results of sensor consistent with the design and operation characters of blade, accuracy and sensitivity met the needs of engineering applications. The tip clearance sensor could be applicative in blade operation monitoring situation of cryogenic compressor.
