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.

A three-dimensional stack-type piezo element has at least one surface that is shaped perpendicular to layer planes of the stack, so that, at least in sections, it is not parallel to a stacking direction of the piezo element.

Nowadays floor structures in the fuselage of airplanes, which floor structures comprise transverse floor girders, are usually connected to the frame on the right and left by means of rivets and are in turn supported vertically downward by the frame by way of Samer rods. According to one embodiment of the present invention a structural element for an aircraft is stated, comprising an active element and a passive element. In this way additional stiffening of the fuselage, a reduction in fuselage deformation, or active vibration dampening can be provided without additional weight.
