where after a pilot took off and landed again quite quickly with one aileron disconnected,( he experienced the wing flapping up and down with gust loads while the aileron was free floating)
Well, it got fluter, right? Thanks God it was not fatal.
Not really the main topic of this thread, anyway, actually the study posted above, this one, take into account the risk of losing some cable tension and as I found in the study there is no flutter even at low cable tension. So, it is somehow confusing. If there's no flutter at low cable tension...
They can go faster but usually it's not a good idea to fly close to red line on the airspeed indicator. Two of the aircraft I use to fly have a pusblished never exceed speed of 130 kts and the other one aircraft 146 kts. In a high dive with full power you can achieve these speeds.
You are right, the limited speed of LSA is a big factor to avoid flutter in normal operation, so it may not be necessary to have mass-balanced surfaces. In normal operation, the aircraft was flight tested for flutter and also in normal service there were no flutter occurences.
However, the...
I found that many certified LSA aircrafts and some standard FAR 23 certified don't have mass-balanced surfaces. I'm interested in how they are designed to show freedom from flutter, especially control surface flutter and if these aircrafts can handle a disconnected freefloating surface emergency...
