ABSTRACT:
A process and device for damping vibrations or preventing their appearance in aircraft airframes in transonic flight. The aircraft has a fuselage carrying on each side a fixed wing (7) provided with at least one propulsion motor. At least one wing (7) is provided with an additional fixed weight (12-14) so arranged that there is more added weight on one side of the aircraft than on the other, the weight being disposed within the volume delimited by the wing (7). Different weights can be added to opposite sides of the aircraft, or all the added weight can be concentrated in one wing, the weight is as close to the end of the wing as possible, beyond the motor or outermost motor of the aircraft.
