Abstract
A compressor frame of a gas turbine engine includes a radially outer ring, and a radially inner ring located radially inboard of the radially outer ring. The radially outer ring and the radially inner ring at least partially define a core flowpath of a gas turbine engine therebetween. A plurality of struts extend between the radially outer ring and the radially inner ring. At least one strut of the plurality of struts includes one or more cooling airflow nozzles configured to inject a cooling airflow into the core flowpath to cool a compressor rotor fluidly downstream of the plurality of struts.
