Experimenting with 12 blade fans with the Viggen. They work fine but are soooooo quiet that it isn't worth the effort. The sound is right - just isn't loud. Has anyone experimented with the expansion chamber to get different sounds (especially with a 12 blade)?
Specifically, I want to know if increasing the expansion chamber size at the rear will get me the whoosh that I'm looking for. I know about the change in thrust vs speed. Looking for sound.
