oa CSIR Science Scope - Research in support of flutter-free aircraft
Flutter is a potentially catastrophic, self-sustained oscillation of an aircraft in flight. Energy is transferred from the kinetic energy of the aircraft to vibration energy through the interaction of elastic, inertia and aerodynamic forces. Once the flutter speed is exceeded, the smallest vibration induced by turbulence, control inputs or engine vibrations will grow exponentially until some non-linear effect alters the conditions necessary for the transfer of energy, or the structure fails.
