Method and device for reducing the vibratory motions of the fuselage of an aircraft. According to the invention, accelerometers (9, 10) are mounted on engines (M1, M4) of the aircraft (1) and, with the aid of the accelerometric measurements thus obtained and of the aeroelastic model of said aircraft, control commands (dZ, dY) to be applied to the ailerons (M1 to M4) so as to counteract the oscillations of said engines are determined.

- Procédé et dispositif pour réduire les mouvements vibratoires du fuse- lage d'un aéronef. - Selon l'invention, on monte des accéléromètres (9, 10) sur des moteurs (M1, M4) de l'aéronef (1) et, à l'aide des mesures accélérométriques ainsi obtenues et du modèle aéroélastique dudit aéronef, on détermine des ordres de commande (dZ, dY) à appliquer aux ailerons (M1 à M4) pour contrecarrer les oscillations desdits moteurs.
