Compressor maps for mathematical model of a gas turbine

[trawsko1990]

Hello,
I`m working on a mathematical model of a gas turbine and I need good compressor maps, especially function of efficiency vs. pressure ratio, inlet temperature, mass flow etc I`ve been looking for this for few days, but can`t find anything interesting.

Do you know where I can something like this? Websites or book?

Thanks for any help ;)

I would imagine that that kind of information would be in a file marked "industrial secrets" and kept locked away.
