Hi
I'm taking research on "oil cooling" systems in engines especially turbo shaft engines used in Helicopters and I want to know what kind of Heat exchanger used in these systems
Can any body inform me books or website or ... about details of this system
P.S: This system cools the oil which used to lubricate and cool bearing or other parts of engine
if there is information about this system in turbo jet or turbo fan, no problem they act similarly and may be helpful but if there is special for turbo shaft it would be so beneficial for me.
Thanks
