Method of finishing a fan blade

摘要

A method of finishing a fan blade 30 includes bonding a sheath and a cover to an aluminum fan blade 30 with an airfoil 32, a root 34, a leading edge 36 and a tip 38; imparting residual stresses onto the blade; coating the blade to protect exposed areas of the blade; and curing the blade in low-temperature cure cycles to preserve residual stresses imparted.
