Rotor assembly for a rotorcraft with torque controlld collective pitch

A rotor assembly for a rotorcraft, comprising a rotor shaft, a torque transmission unit that is non-rotatably mounted to the rotor shaft, a rotor hub that is rotatably mounted to the rotor shaft via an associated angular displacement enabling component, and at least two rotor blades that are connected to the rotor hub and provided for creating an airstream from a rotor assembly inflow side via a respective rotor plane to a rotor assembly outflow side, wherein the torque transmission unit is coupled to the at least two rotor blades on the rotor assembly outflow side via a pitch control unit, wherein the pitch control unit transmits to the at least two rotor blades torque that is applied from the rotor shaft to the torque transmission unit, and wherein the pitch control unit increases a respective pitch angle of the at least two rotor blades if the torque is increased.
