DEVICE FOR REDUCING STRUCTURAL VIBRATIONS OF AIRFOILS

摘要

A device for reducing structural vibrations of aerofoils in an aircraft comprises, in the region of the aerfoil tips, at least one force generator (24a) acting substantially in the direction of movement of the vibrations. This arrangement has the advantage that such a force generator (24a) is considerably less susceptible to wear than conventional aerodynamic flaps and therefore effective vibration damping is possible with a reduced outlay on maintenance and greater efficiency.
