US 2022/0089272 A1 · ANTIVIBRATION KIT-OF-PARTS AND PARTS THEREFOR, AIRFOIL STRUCTURE AND AIRCRAFT PROVIDED THEREWITH

Abstract

To reduce vibration of movable airfoil structures, such as rudders, elevators, and ailerons, a spring device, a leaf spring for example, is mounted to an airfoil mounting structure, such as a vertical tail plane, horizontal tail plane or the wings, such that the spring device exerts a force on a cam device, which transforms the spring force into an airfoil torque. The airfoil torque is applied to the airfoil structure and thus reduces a risk of vibration. The cam device is configured to redirect the spring force such that when the airfoil structure is moved in a first direction, torque decreases and when moved in the opposite second direction the torque is zero.

1-15. (canceled)

An antivibration kit-of-parts configured to reduce vibration of an airfoil structure, the airfoil structure being movably attachable to an aircraft, wherein the antivibration kit-of-parts comprises:

a spring device configured to generate a spring force due to deflection from a spring neutral position of the spring device;
and
a cam device configured to transform the spring force into an airfoil torque while, when both the spring device and the cam device are in an operating condition, the cam device contacts the spring device, and the cam device is configured to apply the airfoil torque to the airfoil structure while, when both the spring device and the cam device are in the operating condition, the cam device is operatively coupled to the airfoil structure.
