Landing gear foa rotorcraft and method for the dissipation of ground resonance oscillations

摘要

A linking system for attaching a cross tube to a skid of a landing gear of a rotorcraft, the linking system comprising a hinge element, means for connecting the hinge element to the cross tube and means for connecting the hinge element to the skid, the hinge element in turn comprising a cross tube-sided part and a skid-sided part able to rotate with respect to one another, a torsion bar spring and a rotary damper element suitable for dissipating a ground resonance excitation energy when the rotation of the cross tube-sided part with respect to the skid-sided part occurs.
