WebAeroelastic flutter, a rapid self-feeding motion, potentially destructive, that is excited by aerodynamic forces in aircraft and bridges. Flutter (American company), a gesture recognition technology company acquired by Google in 2013. Flutter (electronics and communication), any rapid variation of signal parameters. WebNov 28, 2024 · How does this apply to your question: aerodynamic damping is exactly that, the opposition of the aircraft to rotation. You can observe it without flying: just imagine an aircraft hanging by its nose and tail, in such a manner that its CG is right between the supports. You can roll it by hand, but the drag on the wing will eventually stop this ...
