Nowadays turbine blades are protected by thermal barrier coatings. The infrared-optical properties of these coatings require the usage of the MIR or LWIR region for non-contact measurement of the surface temperatures. For performing such measurements and for properly analyzing the derived data, the transmission and absorption spectra of the combustion gas mixture within the turbine were determined at the local conditions during operation of the turbine. Therefore, subject of this work is the measurement of the transmission spectra of carbon dioxide and water vapor at high temperatures and high pressures to identify a wavelength range, which is almost free of absorption and emission effects.

To increase the efficiency of gas turbines higher combustion temperatures and higher turbine inlet temperatures are required. This implies that turbine blades and vanes are exposed to higher temperatures. Advanced thermal barrier coatings (TBCs) based on ceramic materials protect the components from overheating and ensure mechanical integrity. Still, materials and coatings need to be stressed to their limits to reach the challenging goals of an efficiency increase. Under these circumstances, it is crucial to have sensing techniques available that are capable of accurately monitoring the temperature of turbine parts in order to prevent damages within the engine. The approach to overcome current limitations of existing techniques is to use long wavelength infrared (LWIR) pyrometry as TBCs are usually semi-transparent in the near or short wavelength infrared. Therefore one work package within the STARGATE project is dedicated to the development of a LWIR radiation thermometer to measure the surface temperature of TBCs contactless during operation of the gas turbine engines. The paper shortly gives an overview of the investigation performed within the STARGATE project. The construction, calibration and application of the LWIR radiation thermometer is described in detail and results obtained on a test facility are presented. The paper closes with an outlook on future plans of implementing the LWIR pyrometer in the quality system of gas turbine operation.}, language = {en} } @inproceedings{HartmannManaraZipfetal., author = {Hartmann, J{\"u}rgen and Manara, Jochen and Zipf, Matthias and Stark, Thomas and Arduini, Mariacarla and Ebert, Hans-Peter and Tutschke, Andreas and Hallam, Andrew and Hanspal, Jagdevinder and Langley, Mark}, title = {Long Wavelength Infrared Radiation Thermometry for Non-Contact Temperature Measurements in Gas Turbines}, address = {London}, language = {en} } @inproceedings{HartmannKnoppLenskietal., author = {Hartmann, J{\"u}rgen and Knopp, Kevin and Lenski, Philipp and Ochs, Dennis and Z{\"a}nglein, Marc and Stark, Thomas and Zipf, Matthias and Arduini, Mariacarla and Hemberger, Frank and Vidi, Stephan and Manara, Jochen and M{\"u}ller, Michael and M{\"o}ller, F.}, title = {Systematische thermophysikalische Charakterisierung von W{\"a}rmed{\"a}mmschichten}, address = {N{\"u}rnberg}, language = {de} } @misc{HartmannKnoppZaengleinetal., author = {Hartmann, J{\"u}rgen and Knopp, Kevin and Z{\"a}nglein, Marc and Manara, Jochen and Stark, Thomas and Zipf, Matthias and Schreiber, Ekkehard and Kr{\"u}ger, U. and Brunner, Martin and M{\"u}ller, Michael}, title = {Messsystem f{\"u}r dynamische Materialuntersuchung bei hohen Temperaturen}, address = {N{\"u}rnberg}, language = {de} } @inproceedings{HartmannManaraStarketal., author = {Hartmann, J{\"u}rgen and Manara, Jochen and Stark, Thomas and Zipf, Matthias and Arduini, Mariacarla and Ebert, Hans-Peter and Tutschke, Andreas and Hallam, Andrew and Hanspal, Jagdevinder and Langley, Mark}, title = {Entwicklung und Test eines langwelligen Strahlungsthermometers zur ber{\"u}hrungslosen Temperaturmessung in Gasturbinen w{\"a}hrend des Betriebs}, address = {Berlin}, isbn = {978-3-944659-04-6}, pages = {43 -- 48}, language = {de} } @inproceedings{HartmannKnoppLenskietal., author = {Hartmann, J{\"u}rgen and Knopp, Kevin and Lenski, Philipp and Z{\"a}nglein, Marc and Manara, Jochen and Stark, Thomas and Zipf, Matthias and Arduini, Mariacarla and Schreiber, Ekkehard and Kr{\"u}ger, U. and Schmidt, Franz and Brunner, Martin}, title = {Optical Sensor systems for additive manufacturing}, address = {Chengdu (China)}, language = {en} } @inproceedings{HartmannManaraZipfetal., author = {Hartmann, J{\"u}rgen and Manara, Jochen and Zipf, Matthias and Stark, Thomas and Arduini, Mariacarla and Knopp, Kevin and Lenski, Philipp and Ochs, Dennis and Z{\"a}nglein, Marc and Schreiber, Ekkehard and Schmidt, Franz}, title = {Experimental set-up for dynamic material investigation at high-temperatures for power engineering and additive manufacturing}, address = {Freiburg}, language = {en} }
