Abstract
The device comprises anti-cone stops projecting outwards from a common ring that can rotate about the rotor axis on the top face of the hub and flyweights are each individually joined to the ring for driving the latter in rotation from the 'ground' position, in which each anti-cone stop is facing an upper bearing shoe of the corresponding blade, to the 'flight' position, in which the anti-cone stops are retracted, returning them to the 'ground' position.
