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. ------=_NextPart_000_0020_01C39C10.C93C5510 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable RE: [FlyRotary] Re: temps behind radiator?
