fully articulated rotor

fully articulated rotor
A rotor with three or more blades in which the individual blades are free to flap (move up and down), drag (move back and forth in the plane of rotation), and change their pitch angle as they rotate around the disc. This is done by mounting the blades on flapping and drag hinges and pitch-change bearings. See also rotor configuration.
Fully articulated rotor system.
