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.

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?

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. john hauck Ely, NV ________________________________ Message 3 _____________________________________ Time: 07:15:33 PM PST US From: chris davis Subject: Re: Kolb-List: Flight West 2014 John,I wish """""""""""""""""""""""""""""""""""Iwas there also !jjust had my 42nd anniversary and my 63 birthday got married the day i turned 21.WHAT A WOMAN .Have a great trip . your friend Chris Chris Davis KXP 503 492 hrs Glider Pilot Disabled from crash building Firefly On Wednesday, September 10, 2014 3:45 PM, "jhauck@elmore.rr.com" wrote: > > > > >Hi Folks: > >Miracles never cease to amaze me.
