Abstract: A device for applying a bead of material includes a flexible nozzle body which defines a flow-through volume through which a material can flow for the bead of material, which is partially delimited by a walling formed by the nozzle body, having a feed opening for feeding the material into the flow-through volume. The nozzle body defines a mouth region through which the material can exit from the volume. Furthermore, the device includes an actuator system, which is arranged on the nozzle body and is set up to change a cross section of the mouth region while deforming the nozzle body. The walling forms a barrier between the flow-through volume and the actuator system.

Abstract: A method for testing a rotor blade of a wind turbine may include predefining a setpoint bending moment distribution. At least two active load-introducing means may be provided which each engage on a load frame. A first of the at least two active load-introducing means may be configured for introducing load in a pivot direction of the rotor blade and a second of the at least two active load-introducing means may be configured for introducing load in an impact direction of the rotor blade. Also provided is at least one passive load-introducing means. A cyclic introduction of load is effected by the at least two active load-introducing means, where a load introduction frequency of the first active load-introducing means and a load introduction frequency of the second active load-introducing means are selected such that the ratio thereof is rational. A testing device for carrying out the method is also provided.
