Abstract
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.
Claims17
A method for damping torsional vibrations in a drive train of an aircraft, the method comprising:
- determining a torsional moment acting on a torque-conducting component of the drive train using at least one sensor integrated in a drive train component;
- adjusting at least one adjustable damping element located in or on the torque-conducting component of the drive train based on the torsional moment;
- and
- regulating a torsional stiffness of the torque-conducting component to reduce the torsional load in the component.
A drive train in an aircraft, comprising:
- a component that is configured to conduct a torque in the drive train,
- wherein the component includes at least one sensor element integrated in the component, the at least one sensor element being configured to determine a torsional moment acting on the component,
- wherein the component includes at least one adjustable damping element the at least one adjustable damping element being configured to reduce a torsional load in the component to adjust the degree of damping in the component, and
- wherein the component includes a control and regulating unit, the control and regulating unit being configured to evaluate the determined torsional moment, and to control the adjustable damping element based on the evaluated torsional moment.
A torque-conducting component for use in a drive train of an aircraft, comprising:
- at least one sensor integrated in the torque-conducting component and configured to determine a torsional moment acting on the torque-conducting component;
- an adjustable damping element configured to reduce a torsional load in the component to adjust the degree of damping in the component;
- and
- a control and regulating unit, the control and regulating unit being configured to evaluate the determined torsional moment, and to control the adjustable damping element based on the evaluated torsional moment.
