RE: [FlyRotary] Re: temps behind radiator?
For
those too unfortunate, lazy or otherwise distracted to make it to Shady
Bend....
Ed's
talk (all 60 slides of it) was excellent. Very logical and easy to follow. Made
sense every step of the way. Aside from a bit of minor heckling from one
particular individual, the presentatation was very well received by 60 or so
attendees and generated hours of discussion afterwards.
Let me
see if I can summarize the talk without getting into
formulae....
A
strong pulse is generated as the intake port closes. If this pulse can
be provided with a path, and timed to arrive at the opposing intake port just as
it's closing, then the "cramming" of air it causes can generate significant
extra horsepower. Ed has attempted to define and calculate the variables
involved and, while he freely admits that there are numerous unknown factors,
he's got us much closer to an understanding of the mechanics and the issues
involved. For example, street porting your engine can make a big
difference in the impact of the pulse because it shortens the time available for
the pulse to travel to the other port. The next logical
step is practical application of, and experimentation with, the theory. Ed
is working on his next intake with adjustable runner
lengths.
Richard Sohn produced a nice looking 1 rotor engine and gave a good talk
on it's construction.
I got
my new EC2 software installed and checked. Tracy demoed the EM2. I think
the smaller screen looks much neater. There's lots of useful data being
presented, unfortunately mostly digitally. I like the way it works with the
EC2. When asked when it'll be available Tracy tried to say something, but Laura
stuffed a hotdog in his mouth just before the date could be heard. :) I could
have sworn the word began with an "N".
The
new tangential muffler was tested. It looks great, and is a very small neat
package. It's louder than the stock muffler, but for its size it looks like a
very good option. If I wasnt installing a turbo I'd want
one.
There
were 6 rotary powered RVs in attendance, three of which did some airwork and a
fly-by for us.
It
occured to me that everyone who's flown a rotary so far has done all the
engineering themselves. Hmmm.
This morning it was very motivating to hear each one start up,
taxi out and fly off into the distance. MMMMMMMMMMMmmmmmmmmmmmmmmmmmmmmmmm
Overall the fly-in involved good people, good conversation around the
campfire, good food and good weather. There were fly-in attendees from as
far away as Oregon and Toronto. Unfortunately the grass runway is a little
too rough and short for pushers but it was well worth the drive. There's some
talk of an Alternative Engines fly-in at Lakeland.
