Study on the development of thin-film sensor for measuring instantaneous temperature on wall surface of combustion chamber

Thin film sensor that can measure the instantaneous temperature change on the wall surface of combustion chamber was developed in this study. This sensor was directly forms on combustion chamber surface by PVD(sputtering) method. In this study, with respect to the instantaneous temperature measurement accuracy using this thin film sensor, the optimum shape of the sensor was investigated by analysis, and additionally, an example of the measurement result by this sensor was shown in a rapid compression and expansion machine reported.
