Temperatures in "cold" section of turbine?
I would like to know roughly how hot the air becomes at the last stage of compression (before it reaches the combustion chambers) in a modern turbine.
Reason I'm asking is because I've heard differing things - one is that the compression stage section is relatively cold and could therefore be made out of non heat resistant materials such as composites etc. The other is that compressing air creates lots of heat and hence the opposite. Which one is true?
