The useful part of that email was "two inlets, two outlets". The rest of it was either lecturing, standard cozy implementation or self agrandizement. I did a search for muffler (title only) and found 100+ emails in the last year. People here are contributing lots to the advancement of the art. regards, Dave Wilenius Cozy Plans # 796 http://wilenius.webcentre.ca -----Original Message----- From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net]On Behalf Of Al Wick Sent: June 7, 2008 4:57 PM To: Rotary motors in aircraft Subject: [FlyRotary] Re: Mistral Crash Analysis C'mon guys. You do this every time there's a crash. Instantly go into rationalization mode. It's unhealthy. Greatly increases risk builders won't take action. Increases risk you won't research it thoroughly. A healthy response would be:" Here's another example of how our engines produce unusually destructive exhaust temperature and pulses. We have a rich history of broken exhaust components. We need to be very thorough when designing and building exhaust." I designed my own muffler. It had two inlets, two outlets. So if (when) my muffler failed, it could never block both pipes. I also put loose safety wire around my pipes, because on a pusher loosing pipe wipes out prop. So basically, I assume stuff will fail, then design it to control the way it fails. I've heard of rotary guys doing same type of thing. This is a good time to share those key items. On your car, they deliberately design products to fail a certain way. They will make a component weak, so it fails first. They do that with wheels and hubs. So when the muffler fails, little pieces come apart, not big sections? You guys do a great job of sharing successes, design and construction details. This is another opportunity. -al wick ). But, I serious doubt it will effect many who have researched the rotary and come to understand its benefits - as for the rest, who cares {:>) > I'm certain it was a relief to Mistral that the culprit was not one of their engine components. Whew! a close one for sure. Hi Ed, Unfortunately, I bet the majority of people will only hear "Mistral rotary", "lost power", and "crash" :-( Rusty (RV-3 taking forever.) ____________________________________________________________ Orlando Vacations - Click Here! http://thirdpartyoffers.juno.com/TGL2141/fc/Ioyw6i3nK7u59LkagfZ5IcEgGqYcvPRC wA85GgQITbFK9vE7wPGKFP/ -- Homepage: http://www.flyrotary.com/ Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html
