| Subject: | vibrations (again :) |
Hi All,
I posted this over on the Rotax list as well, but thought I would try here too.
Some of you know (as you have been helpful off list) that I have been trying to
solve a prop vibration issue.
Well, I am pretty sure it is solved. (via a new prop)
The spectrum I get now shows a small peak at 3xpropRPM and at propRPM I am in the
noise floor of the data. So the contribution to vibration is small.
Sadly, I can't flight test here just yet, as I am waiting for some paperwork to
come through for the national reg change. So I can not do the final closeout
of the issue. I hope to do so in the coming weeks.
In the meantime, I want to try to understand some further points on the spectra
I gathered from the tests.
I can see two large peaks. One is at crankRPM and the other at halfCrankRPM.
Can anyone help out with what is a normal vibration level to see from the spectrum
at the crank and half-crank frequencies for a Rotax 912UL (80Hp)?
I have data spanning engRPM of 2300 to 5200. The peaks obviously increases as the
engine speed increases.
Cheers
Jon

I need a woodcomp controller. I have the prop but no controller. Do you have a

Thanks

Karl - thanks for the thought. If the CSC-1 dies on me and Mark cant fix it, Id
buy a Woodcomp constant-speed unit. Their latest ones seem to offer similar capability
to Marks unit now, although when I bought my prop their constant-speed
controllers were, as I recall, a bit more agricultural.
And for anyone else thinking of asking for my controller, Ive already had 3 requests
and am trying to discern the most deserving case!

I think agricultural is the right word. I spent a whole summer trying to ge
t it to work, and I am glad to hear that they have a decent unit now.

I was hoping my fan was reversible (constipating airflow in the radiator
could be handy at low engine power levels too...say 55% and less), but
unfortunately it wasn't..

For not many amps, I can run in reverse and constipate any excess airflow
through the radiator I don't want. For one when things are over-cooling in
cooler weather,
