| 发明名称 | Fan blade finishing | ||
| 摘要 | A method of finishing a fan blade includes bonding a sheath and a cover to an aluminum fan blade with an airfoil, a root, a leading edge and a tip; 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. | ||

| 主权项 | 1. A method of finishing an aluminum fan blade with an airfoil, a blade root, a leading edge and a tip, the method comprising: bonding a sheath and a cover to the aluminum fan blade; imparting residual stresses onto the aluminum fan blade by peening; coating the aluminum fan blade with a first primer to protect exposed areas of the aluminum fan blade; bonding wear pads to the blade root with a first adhesive; painting the aluminum fan blade with a coating; and curing the first primer, the coating, and the first adhesive in low-temperature cure cycles below 250 degrees F. (394 degrees K) to preserve residual stresses imparted. | ||
