Rotor, rotorcraft comprising a rotor of this type and method for adjusting the blade angle of a rotor

The rotorcraft rotor as recited in claim 19, wherein the integral, bearingless, centrifugal-force-controlled blade angle adjustment device includes at least one rotor-blade connector arm impinged upon by centrifugal force during rotor operation and having a rotor-head-end connection point and at least one staggered or angled arm portion formed between the rotor-head-end connection point and a vector, wherein the vector is one of a centrifugal force acting on the at least one rotor blade, and a component of the centrifugal force acting on the at least one rotor-blade connector arm, and wherein the staggered or angled arm portion forms at least one lever arm with which the rotor-blade connector arm and the rotor blade are twistable in response to the centrifugal force.

The rotorcraft rotor as recited in claim 19, wherein the rotor blade includes a rotor blade neck, wherein the integral, bearingless, centrifugal-force-controlled blade angle adjustment device includes a foot region terminating in the rotor-blade neck, and wherein the at least one least one rotor-blade connector arm includes at least two rotor-blade connector arms impinged upon by centrifugal force during rotor operation and extending from the foot region at a distance from one another, and wherein at least one of the at least two rotor blade connection arms includes an arm portion that is staggered or angled with respect to another of the at least two rotor-blade connector arms.

The rotorcraft rotor as recited in claim 19, wherein the rotor is part of a rotorcraft.

A rotorcraft, in particular a helicopter, in particular a tiltrotor helicopter, comprising at least one rotorcraft rotor as recited in claim 19.

A method for adjusting a blade angle of a rotor blade of a rotorcraft rotor that includes a rotor head and a rotor-head-end bearingless rotor-blade connector, the method comprising:

• rotating the rotor blade so as to create a centrifugal force acting on the rotor blade;
• and
• twisting the rotor-head-end bearingless rotor-blade connector using the centrifugal force so that the rotor blade is twisted about a longitudinal axis of the rotor blade so as to automatically adjusting a blade angle.
