rudypoochris Posted November 24, 2005 Share Posted November 24, 2005 I've always wondered why engine fan blades aren't evenly spaced...any reason for it? Some arn't, from my experience many are. It is to keep the noise down. Don't remember how it works, but different spacing lowers the noise level according to some advertisements I have read.
