In this work, the infrared-optical properties of the thermal barrier coatings and the combustion gases were determined at ZAE Bayern at high temperatures up to 1600 K and pressures up to 13 bar. Based on these experimental characterizations, a suitable spectral range could be identified which lies around 10 μm for the long-wavelength infrared radiation thermometer. According to these findings, a laboratory setup with suitable optical components (filters, IR-fibers, etc.) was firstly realized and verified. Subsequently, a prototype for measurements in gas turbines during operation of the turbines has …}, language = {de} }
