Enhanced Turbine Cooling System Using a Blend of Compressor Bleed Air and Ambient Air

The present application provides a gas turbine engine for low turndown operations. The gas turbine engine may include a compressor with a compressor bleed air flow, an ambient air source with an ambient air flow, a turbine, and an eductor. The eductor blends the compressor bleed air flow and the amb...

Zusammenfassung:	The present application provides a gas turbine engine for low turndown operations. The gas turbine engine may include a compressor with a compressor bleed air flow, an ambient air source with an ambient air flow, a turbine, and an eductor. The eductor blends the compressor bleed air flow and the ambient air flow into a blended air flow for use in cooling the turbine.
