ABSTRACT:
A method and a device reduces the vibration generated on the structure17of a helicopter2by the flow of air through the main rotor5and by the flow of air along the fuselage3. The device1includes: at least one sensor18, 19, 20measuring the vibration generated on the structure17; and computer element30responsive to the vibration measurements to determine variation in the angle of incidence of a tail fin9of the helicopter2suitable for generating an opposing force {right arrow over (T1)}, {right arrow over (T2)} for opposing the vibration, and transmitting the variation in angle of incidence as determined in this way to a control system10for controlling the angle of incidence of the tail fin9.
