ABSTRACT:
A free-floating damper system is provided wherein a damper housing is configured to receive a damper arm for free-floating movement in the x/y plane while restricting similar movement in the z plane. The damper arm is specially configured with first and second wear bushings positioned in a spring biased support to insure the frictional generation of coulomb dampening forces between the damper arm bushings and the damper housing. The damper can be fixedly mounted to a portion of a gas turbine engine such as the turbine frame and a portion of the damper arm can be attached through a mounting bracket to an accessory tube of the engine to dissipate vibrational forces which otherwise can damage the accessory tube.
