Abstract
A fan blade damper system includes a fan disk integrally connected to a disk post. A retainer is fastened to the disk post and is molded to retain a damper block. The top portion of the damper block is shaped to make frictional contact with the underside of the platform of a fan blade, the underside of the platform being the region of the fan blade which experiences the highest platform vibratory amplitude when the fan blade is rotated. The damper block is thus mounted in a statically determinant fashion. The rotation of the fan blade produces centrifugal forces which produce reactionary forces in the damper block and retainer such that a maximum damping force amplitude is reacted to the fan disk.
