PROBLEM TO BE SOLVED: To provide gas turbine cooling systems to provide adequate cooling even during extreme turndown operations without a loss of overall efficiency, a decrease in a component lifetime, or an increase in undesirable emissions.SOLUTION: A gas turbine engine 100 may include a compressor 110 containing a compressor bleed air flow, a turbine compartment 190 containing a turbine compartment air flow 225, a turbine 170, and an eductor 230. The eductor 230 blends the compressor bleed air flow and the turbine compartment air flow into a blended air flow 280 for use in cooling the turbine. |
