摘要： A helicopter rotor on which each blade is connected in articulated manner to a center hub by means of a fork, the vertical plane movement of which is limited, below a given speed of the rotor, by a pair of limit rocker arms located between the hub and a ring nut mounted for rotation on the fork and angularly integral with the hub by means of a rod of variable length connected in articulated manner to a slide supported on the hub and arranged substantially horizontally and crosswise in relation to the blade.

摘要： Helicopter rotor on which each blade is connected in articulated manner to a center hub by means of a forkthe vertical plane movement of which, at rotor speeds below a given set value, is limited by a pair of limit rocker arms located between the hub and a ring nut mounted in rotary manner on the forkand rendered angularly integral with the hub by means of a compass drive.
