In electronics and engineering, flutter is any rapid variation of signal parameters. Other uses include:

  • in aircraft structures, control surfaces and bridge engineering, aeroelastic flutter is a rapid self-excited motion, potentially destructive, usually present above some limiting aircraft speed.
  • In aeronautics is, in a few words, an unstability of the aircraft's structural vibration modes due to aerodynamic forces presents.
  • in suspended fabric such as flags or clothing, rapid motion due to wind.
  • flutter is also the qualitative perception that follows stimulating the skin with a point probe vibrating close to 40 Hz.
