Subject: [FlyRotary] Aeroturbine muffler

 

OK, while Ed is waiting for his side housings to arrive I thought I would ask if anyone has heard, or tried this muffler.  Here is a snip from their description of the truck/SUV muffler model 3030, which has a 3’ inlet/outlet.  They also make 2.5”, 3.5”, 4” and 5” inlet/outlet models.  It comes with a lifetime warranty <big grin>.  It looks to be very streamlined, made of SS, lightweight, and has no packing. It sells for less than $200 (except for the 5” model).  This looks like this just might be what I’ve been looking for.  More info available at http://www.pickupspecialties.com/Aero_Turbine/aeroturbine_mufflers.htm.  Comments???

This muffler is quite similar to the one I designed and had fabed out of 321 SS by Custom Aircraft Parts.  The difference is that in theirs the gas expands freely in the front portion of the muffler; mine expends through an inner perforated tube wall.  The basic concept is the same, but I can see where their design may be better.

 

You may want to check with http://www.customaircraft.com and see how much they would charge to make a few knockoffs out of SS321, or even inconel.
