Abstract
A rotor, in particular for a rotorcraft, encompassing: a rotor head, at least one rotor blade, and a rotor-head-end rotor-blade connector having an integral, bearingless, centrifugal-force-controlled blade angle adjustment device. A rotorcraft, in particular a helicopter, in particular a tiltrotor helicopter, encompassing at least one such rotor. A method for adjusting the blade angle of a rotor blade of a rotor, in particular of a bearingless rotor that possesses a rotor head and a rotor-head-end rotor-blade connector, encompassing the following steps: rotating the rotor blade; and automatically adjusting the blade angle by twisting the rotor-head-end rotor-blade connector, and thus the rotor blade, about its longitudinal axis by means of centrifugal forces acting on the rotor blade.
