Patent ID: 8328129

Claim:
A vibration-attenuating link for mounting a pylon on an aircraft, the link comprising: a singular rigid body having opposing ends pivotally connected to both the pylon and a rigid structure of the aircraft, the rigid body enclosing an interior volume; a first volume and a second volume, the first volume and the second volume being at least partly defined by an interior surface within the interior volume of the rigid body; a mass separating the first volume and the second volume, the mass being configured as a piston such that the mass is moveably sealed to the inner surface of the rigid body; a first fluid line in fluid communication with the first volume; a second fluid line in fluid communication with the second volume; a third fluid line in fluid communication only with the first and the second volume; and a fluid disposed in the first volume, the second volume, the first fluid line, and the second fluid line; wherein the mass is moveably carried and translates within the interior volume of the rigid body in communication with the inner surface in response to commands by a controller, the controller being configured to move the mass in an oscillatory manner so as to create oscillatory forces; wherein the oscillatory forces react against vibratory forces transferred into the body.
