Paul,
I'm not an engineer so help me out here.  I get some junk mail from an
Army-Navy surplus type that sells guns, parts and books.  One of the
manuals
they sell is a study done on the fabrication of silencers for guns by some
government arsenal.

Now my question; How does the detonation of a gun and the detonation of an
engine differ other than in the sound wave speed and frequency?  If one
can
silence a gun can't we do the the same with the rotary?   Do you think any
of the techniques of gun silencers would be applicable to silencing of our
Mazda rotaries?  Wasn't some Detroit grad student on the list going to
help
us make the rotary purr like a kitten?

There are some similarities that's for sure.

That is my understanding, but thier could be other more advanced methods.
We do not have projectiles (well we arwen't suposed to anyway), and they
also aren't trying to silence 4500 bangs a minute.

I don't want to rain on your parade though, sometimes you have break the
rules to make great strides.  May be worth a looksy.  If nothing else you
could silence your favorite varmit getter and stop disturbing the neighbors
<grin>.

10,000 bangs a minute at 5000 RPM.
