Abstract

For future low emission aero engine combustors a significant reduction of cooling air consumption is required. Quantitative data of the performance of advanced cooling concepts in a realistic environment in addition to existing data from scaled isothermal investigations is needed by combustor designers for further improvements. The effect of the cooling air properties on the cooling effectiveness of different advanced cooling concepts at realistic operating conditions is analyzed. Adapting of the measuring techniques and correction of the exhaust gas radiation will be especially addressed. An introduction into basic cooling design considerations is included.
