| The correct answer is C) 13th stage compressor air. In the GE LM2500 gas turbine engine, the high-pressure (space waves ) turbine 1st stage nozzle vanes are cooled using air extracted from the 13th stage of the compressor. This cooling air helps maintain the structural integrity of the nozzle vanes by reducing the thermal stress caused by the high temperatures in the turbine section. |
