The invention relates to a method and an arrangement for the wings of a high 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 t...
An apparatus for increasing the flutter velocity or speed of an aircraft, comprising sensing means for sensing a threshold signal anticipating an onset of an instability causable by flutter, signal processing means operatively connected to said sensing means for producing of the sensed threshold signal a control signal representing an anticipated onset of a flutter instability, aerodynamic damping means (13, 14), operating means operatively connected to said signal processing means and to said damping means (13, 14) for automatically placing said damping...
