The science studying how air forces affect and interact with flexible or moving parts of aircraft and structures, causing them to bend, twist, and vibrate.
From aero- (air) and elasticity (property of returning to original shape). Developed as a formal discipline in aerospace engineering during the jet age when understanding these interactions became critical for safety.
Some of the earliest jet crashes were caused by aeroelastic flutter that designers didn't understand—now engineers study this field intensely because a vibrating wing at supersonic speed can literally tear an airplane apart!
