| Subject: | Anti Flutter idea.... |
Nick,
I think your thought process has some merit however, it did not quite go far
enough.
Putting a damper on a control surface should indeed help prevent flutter
(oscillations).
A thin light weight fiberglass or carbon fiber rod would probably provide
the force needed to do the job, insofar as it would absorb some of the
energy used to move the control surface from neutral to non-neutral.
Unfortunately, this is where the usefulness of the rod (spring) comes to an
end. Now that the spring has all of this stored energy, the only way it can
release it is back into the control surface. In flutter, the surface is
going to oscillate and the release of the stored energy will only contribute
to the problem, adding force to the opposite motion, thus making it worse
instead of better.
In short, the rod helps during the first half of the flutter motion, but
hurts during the second half. At least until the surface gets back to
neutral, then the process starts all over.
What you attempted to do was add a dampener, but what actually happened was
you added a spring.
There probably have been entire books written on this subject, all of which
I am sure are way beyond me.
A shock absorber of the right size would probably work. Keep thinking, you
may come up with a solution that is totally new.
Just my $.02 and a few electrons.

Subject: Kolb-List: Anti Flutter idea....
Hello Kolbers,
I had a though about aileron flutter.I have these heavy counter weights that
I will be installing on the outboard ends of my ailerons soon.
Disclaimer. I am a True "amateur" so please tell me why this idea is a bad
one!
If the idea of these weight is to apply resistance to keep the aileron from
fluttering, could this function not also be accomplished by install a
fiberglass rod running along the bottom of the end wing rib, and continuing
out to the end of the aileron. The rod would flex up or done through the
movement on the aileron, but would dampen the aileron movements. Ok, what do
you think? Has this ever been tried..did the pilot live?
Thanks,

Hi Folks:
Miracles never cease to amaze me. I found a computer that works at the airport
in Ely, Nevada.
Decided to celebrate my 75th year with another round trip across CONUS. Haven't
been through Monument Valley in 5 years, so decided to take the long way to
the next Kolb/Rock House Flyin near Burns Junction, Oregon. Departed Gantt International
Airport, Titus, Alabama, Sunday morning at 0800. After 8 hours of
flying, landed at Sherman, Texax, where I spent the night in the FOB. Another
8 hours of flying got me to Los Lunas, New Mexico, where I spent the night with
friends at Midland Airpark. They are also flying to the Rock House, Friday.
Yesterday I flew 4 hours and after the third attempt, got the Kolb MKIII on
the ground. Wished I had had a video camera. It was exciting. Landed in a
rain storm, unusual for MV, with extreme cross wind. Velocity, I do not know,
but don't want to do it again. Today I have flown 4 hours. I have another 2
hours to make Elko, Nevada, where I will dine at the Star Hotel, enjoy some wonderful
Basque food (I've been here before), and spend the night with friends.
Tomorrow will be an easy 2 hour flight across the mountains to the Rock House.
If I deviate to the east a little, there is a gravel strip at Owyhee, NV.
Other than that, it is high desert wilderness and mountains with pointy tops.
Wish you all were here.
