A torsional moment acting on a component in a drive train of an aircraft may be determined using at least one sensor, where the determined torsional moment is used for adjusting at least one adjustable damping element located in or on the component and/or for regulating a torsional stiffness in the torque-conducting component. As a result, the torsional load in the component may be reduced.

Method for damping torsional vibrations in a drive train, and drive train

The invention relates to a belt drive assembly for a drive train of a helicopter, comprising a drive shaft that can be functionally connected to a crankshaft of a drive machine of the helicopter, wherein the drive shaft is functionally connected to a belt disk via a torsional vibration damper, wherein the belt disk can rotate via a bearing mechanism on a bearing shaft connected to the drive shaft for conjoint rotation therewith, wherein the belt disk can receive a belt that is functionally connected to a rotor system of the helicopter.
