In development process of cooled turbine blade, precise prediction of the blade temperature at the design stage and precise temperature measurement in the prototype engine test are both very important for reducing the turn around time of the development process. With respect to the metal temperature prediction, CHTflow(Conjugate Heat Transfer and flow ) analysis results which KHI applied to the cooled blade design in collaboration with IDG (Institute of steam and gas turbine, Aachen University) are presented, and with respect to the temperature measurement, the blade temperature measurement results by some methods including the thermal index paint and the latest pyrometer system are also presented.
