Abstract
Système d'isolation de vibrations. Chaque point d'accouplement comprend en plus d'un ressort d'accouplement, un bras de levier lesté d'un poids, relié de manière pivotante à la masse vibrante et au corps, la connexion à pivot entre corps et levier étant située entre le centre de gravité du bras et la connexion à pivot entre masse vibrante et levier. Isolation entre rotor et fuselage d'hélicoptère.
