Included in operation: Fairing, vibrating mass, central rod, self-lubricating bearing, 3 springs. The vibrating mass weight "m", is installed on the rod and the bearing on the central axis of the rotor mast.
The vibrating mass is held by 3 springs rigidness "k", which allow it to oscillate on the horizontal plane and in all directions.
The vibratory system "m, k", excited by the regular vibrations of the main rotor, acts in opposition to the excitation frequencies.
The assembly improves the vibratory level of the aircraft within the whole flight envelope.
