Subject: [FlyRotary] Re: What should you
expect was : first flight Tracy's old prop.
We both would get a nominal 5200 rpm static (on cold
mornings due to the EDDIE effect my static would go as high as 5600-5800
rpm). In my 120 mph (TAS) WOT climbout I normally would get from
5600-5800 (depending on OAT). So if you are not getting at least 5000
static, you have some tuning to do.
Thanks for the extra data. So you figure that your 5200
rpm static is WITHOUT the benefit of the EDDIE effect? Now I'm
really depressed. I'm getting 4700 static, and 4900 in climb at 120
mph.
IIRC,
in a previous message, you mentioned that there were two general paths of
intake design, one being low restriction to mass flow, and the other
being tuned effect. Mine is likely neither, so at least going to a short
intake could buy me something. At the moment, I'd be happy to get up to
your non-EDDIE static rpm.
Hey
Paul. You have an identical intake to mine. Have you been able to
do any full power runups? With what prop? What
RPM?
Hi,
Rusty.....I do not have a prop installed, as it would blow everything out of
the garage. I have had the engine up to around 4500 rpm at around 1/3 to
1/2 throttle, but that's without the load from a prop. I am hoping to get the
airplane to the airport in the next week or two and install the prop, then see
what kind of run-up rpm's I get. I talked to the guy who sells the new
Mistral rotary engine, and he said that my intake is very similar to what they
were using. They are presently changing it to relocate the injectors
very close to the intake of the engine, however it will still have the
wrap-around intake like we have with the throttlebody on the cold side of the
engine. I have a picture that he sent to me if you are interested.
