After lurking on Airliners forums for a long time, I joined the club. Please excuse me if my questions are trivial or allready being answered. I tried to search but I couldn't find anything.
Now to the question:
Jet engines are air-breathing machines. The more oxygen you can cram into combustion chamber, the more power you can get from it (as long as other things like EGT, RPM etc. are in check), right?
Air gets hotter when compressed. In ideal world it would follow ideal gas law, PV
=nRT. In case of airplane engines, I guess it will get a tad hotter due to compressor inefficiencies. When air is compressed dozen times, it will be very hot when it reaches the burner cans, then get even hotter when fuel is burned.
Now what if you added a short heat exchanger between LP
compressor? You could use a short water circuit that would circulate the coolant trough say, leading edges (thus making a permanent anti-ice solution). This "Intercooler" (to use automotive terminology) would probably make little more resistance to the flow, but to make it more flow-friendly, you could incorporate it into stator vanes, thus making them both a cooling element and a stator?
A pessimist would probably say that such solution would be too complex and heavy, but hey...P&W are trying to make a geared fan for 20 years, and that's a tad more complex than circulating little coolant trough few bits and pieces
That way, you could achieve higher pressure ratios and make engine more effective??
Now shoot me down in flames...
