    • A rotorcraft rotor with hinged blades, includes: a hub; a plurality of blades hinged to flap relative to the hub; bottom abutments of the hub, and bottom abutments of the blades suitable for co-operating with the bottom abutments of the hub; and top abutments of the hub, and top abutments of the blades suitable for co-operating with the top abutments of the hub; the top abutments of the hub being movable between a deployed position in which they extend facing the top abutments of the blades, and a retracted position in which they are offset angularly away from the top abutments of the blades. The rotor also includes elements for locking the top abutments of the hub in the deployed position, and inertial means for releasing the top abutments of the hub and for deactivating the locking means.
    • 具有铰接叶片的旋翼航空转子包括:轮毂; 多个叶片,其相对于所述轮毂铰接以折叠; 轮毂的底部支座和叶片的底部支座适于与轮毂的底部基座配合; 和毂的顶部支座,以及适于与毂的顶部基台协同操作的叶片的顶部基台; 轮毂的顶部邻接件可以在展开位置之间移动,在展开位置之间,其展开面向叶片的顶部支座,以及缩回位置,在该缩回位置,它们与叶片的顶部基台成角度偏移。 转子还包括用于将轮毂的顶部抵接件锁定在展开位置的元件,以及用于释放轮毂的顶部支座并用于停用锁定装置的惯性装置。
