    摘要: The invention relates to a method and an arrangement for the wings of a h speed aircraft, for increasing the flutter velocity. Aerodynamic auxiliary flaps or vortex generators are placed into an effective position in response to filtered sensor signals for causing a reduction in the local lift rise or for shifting the local neutral point toward the wing trailing edge to thereby provide an effective "flutter brake". The auxiliary flaps or vortex generators are activated only once when needed and stay in an activated effective position for a length of time sufficient for increasing the flutter velocity or speed and the activation takes place rapidly in about 200 to 400 milliseconds from the time the sensors pick up or provide a signal for such activation.
