Abstract

A rotor brake for a rotary-wing aircraft includes a rotor shaft, a braking-force actuator configured to be hydraulically actuated, a braking-force pick-up element connected to the rotor shaft and operationally connected to the braking-force actuator, an electromechanical piston control element, and a first hydraulic line connecting the electromechanical piston control element to the braking-force actuator so that the braking-force actuator can be actuated electrohydraulically by the electromechanical piston control element.
