KR> Flutter and flight testing

HI All, Finding your flutter speed sounds pretty important and I may try - carefully. But we must not forget that flutter can happen at any speed - and can change. Flutter inducing dynamics increases with speed, but flutter speed can decrease dramatically with changes in rigging, weight, sti

Re: KR> Flutter

Below is a copy of what I posted to the group in 2008 with better instructions for the flutter testing than I just posted a few minutes ago. Read it as Bud wrote it, not as I botched it in the previous email. This is probably a good time to bring up flutter testing. I have attached some excerpts

Re: KR> Flutter

I brought up flutter recovery several months ago from someone who had encountered it, and again under this thread. I wish we could discuss recovery. My late friend said to me (some 30 years ago), not to apply ANY control input (unless absolutely necessary to avoid the ground) and just take off th

I'm glad you guys are discussing this. Last weekend I had gotten up the nerve to do a low pass, when you push the nose over with an O-200 out front she gains speed very quick. Even though I held her back at 195 mph she would have easily hit numbers way beyond that. A friend of mind was watching

This is probably a good time to bring up flutter testing. I have attached some excerpts from emails with Bud Davisson about flutter testing on the Midget Mustang. Most of you will recognize who Bud is. Aside from being probably one of the best know aviation authors, quasi test pilot, owner of t

OK, so what do you do if you actually get flutter, when testing. Scary. See N64KR at http://KRBuilder.org - Then click on the pics See you at the 2007 - KR Gathering There is a time for building and a time for FLYING and the time for Flying has begun. Daniel R. Heath - Lexington, SC ---Orig

Here's another interesting site (at least to me). http://www.vansaircraft.com/pdf/hp_limts.pdf I don't know about the rest of you, but I never realized that flutter is a function of TAS rather than IAS. Guess I never thought about it. Vne is assigned an IAS, as is stall speed maneuvering spe

I respect airplanes as much as I love them, so when they talk to me I listen. Not many things in airplanes scare me, but when they do - I feel compelled to tell fellow aviators. We have talked about carb ice - I have told you what I know and I will be happy if my input helps one person avoid a ba

Flutter is an aerodynamically induced vibration . As the amplitude of the vibration increase, catastrophic failure of the structure can occur. Regards, Larry A Capps Naperville, IL "Experience is something you don't get until just after you need it." -Original Message- flutter
