Numerous experimental investigations have been performed with a model V84.2 100 MW / 60 Hz gas turbine up to peak load conditions. The paper presents an overview of the most interesting experiments. In detail, pyrometric measurements of the first stage turbine blade are described and discussed. Surface temperature distributions are presented in the form of contour plots, and a comparison with theoretical predictions is shown exemplarily. Moreover, the effect of turbulence promoters on the cooling channel side walls is demonstrated.
