Temperature measurement of high speed rotating turbine blades has been conducted successfully by using an optical pyrometer. The measured blades are the first stage turbine blades of Kawasaki’s gas turbine M7A-01 and rotate at 14,000rpm. In the experiment, the radiance emitted from the blade was collected by the detector, and temperature was calculated from Planck’s equation. The resultant temperature distribution was compared with the result of thermal index paint quantitatively. Also temperature value was compared with the results obtained with thermocouples embedded in the blade. In this paper, details of measurement and analysis are described.
