Keywords: gas turbine combustor cooling, test facility

Lean low emission combustion requires a significant cooling air reduction. Experimental data of cooling concepts at elevated pressures and temperatures typical for a modern gas turbine combustor are needed to validate correlations and CFD calculations. A new combustor cooling test rig and measurements in the hot gas flow are described.
