In aerospace research, flutter generally refers to undesired and self-sustained vibrations in turbine blades that can readily grow out of control, destroying them along with the engine and even the aircraft's wings.

Through experiments on a turbine test rig, researchers found that before the onset of flutter, one particular blade begins to act as a central hub in the network and adjacent blades start to oscillate in sync with it. This leads to the collective synchronization of all blades, resulting in potentially catastrophic flutter.
