i am making a mini scale jet engine for a RC model.
And I try to make the jet engine provide more power.
It means that the fan of the jet engine needs a cooling system for the blades.
I saw that there is a special cooling system called vortex tube.
Can I use it to inject the iced cool air inside the fans in order to make the blade cold?
Is there a kind of jet engine you know using the same mechanism to cool the fan?

I am building a miniature jet engine for a remote-controlled model and seeking to enhance its power output. This requires a cooling system for the engine's fan blades. I have come across a unique cooling system known as the vortex tube, which could potentially be used to inject cold air into the fan to cool the blades. Are you aware of any jet engines that employ a similar cooling mechanism for their fans?
