On some engines I have seen The spinner has a little bit of rubber on the very tip of the spinner to stop Ice build up by vibrating , how do other engines do this? engine bleed air?

RR Fan Engines have the rubber tip, GE & PW don't bother with anti-iceing the spinner.

RR Spey's & Conways used bleed air to antice the inlet dome.

PW didn't antice the JT3D dome

PW did design the 305 with anti-ice in mind, the spinner is provided engine bleed air full time

I don't know the 305

the PW 305 is used on the Lear 60 and the Hawker1000.
it is a 4600 lbs of thrust on the 60, a small engine relatively speaking, but a real kick in the pants if you ever get to ride in a 60.

Yes, the rubber tip is there for anti-ice primarily and is very efficient. It is a RR patent, I believe.
Some poeple suggested if might have been introduced at RR because an executive poked the original spinner tip in his ear or eye while walking around an engine on the floor... talks?
