Fan blade protection system

摘要

A method (60) for protecting a fan blade with an airfoil, a tip, a root and a sheath, the root to be inserted into a hub, includes peening the airfoil of the blade (62); inserting a scrim cloth between the fan blade and the sheath to galvanically isolate the fan blade from the sheath; bonding the sheath to the blade with an epoxy adhesive (64); peening the blade root (66); bonding wear pads to the root with epoxy adhesive to galvanically isolate the root from the hub; applying a protective cover to the tip of the blade (70); and applying a coating to all exposed areas of the blade to inhibit corrosion (72,74).
