The reduction of helicopter vibrations has traditionally been a difficult task to perform. Current anti-vibration devices are passive or semi-active and have now reached their limits in terms of performance and vibration reduction. Moreover they are less adapted to variable NR, which is now present in all new developments because of its aerodynamics and acoustic achievement. It is therefore ineluctable to develop an active anti-vibration device. This paper is devoted to a new generation of active anti-vibration systems developed for the helicopter. It gives an overview of the development methodology from the initial theoretical calculations up to flight test validation.
