Abstract

Abstract Translated from French L'invention se rapporte à l'aéronautique et a pour objet un dispositif de suspension pour hélicoptère comprenant une platine souple (19) au centre de laquelle est fixé le fond de la boîte de transmission principale (15) dont le sommet est soutenu par des barres obliques (25) articulées. La platine (19) offre des bras radiaux (19b) articulés en (27) à la base des barres (25) et en (23) au fuselage (21) de l'hélicoptère. Ces bras portent enfin des masses battantes (24) créant des forces d'inertie avec des réactions aux points d'attache de sens opposé aux réactions élastiques de déformation de la platine. Applications à la réduction des vibrations à bord des hélicoptères. The invention relates to aeronautics and relates to a suspension device for helicopters comprising a flexible plate (19) in the center of which is fixed the bottom of the main gearbox (15) the top of which is supported by articulated slashes (25). The plate (19) offers radial arms (19b) articulated at (27) at the base of the bars (25) and at (23) at the fuselage (21) of the helicopter. These arms finally carry swinging masses (24) creating inertial forces with reactions at the attachment points in the opposite direction to the elastic reactions of deformation of the plate. Applications to the reduction of vibrations on board helicopters.
