CA 2683252

A method is disclosed for suppressing vibration in an aircraft having at least one pair of multiple-blade rotors. The first step of the method is to install in the aircraft at least one pair of vibration suppression devices to form a system, the devices of each system being mounted on opposing sides of the aircraft. Then, during operation of the aircraft, the next step is to rotate the at least one pair of rotors in a manner that causes the blades one of each pair of rotors to be out of phase from the other of each pair of rotors. The final step is to use the system to suppress vibrations caused by the out-of-phase rotation of the rotors.

L'invention concerne un procédé destiné à supprimer les vibrations dans un aéronef possédant au moins une paire de rotors à pales multiples. La première étape de ce procédé consiste à installer dans l'aéronef au moins une paire de dispositifs de suppression de vibrations afin de former un système, les dispositifs de chaque système étant montés sur les côtés opposés de l'aéronef. Puis, durant le fonctionnement de l'aéronef, l'étape suivante est de mettre en rotation ladite paire de rotors. L'étape finale est d'utiliser le système en vue de supprimer les vibrations entraînées par la rotation déphasée des rotors.
