Abstract:
A blade (100) has an airfoil (106) having a leading edge (114), a trailing edge (116), a pressure side (118), and a suction side (120) and extending from an inboard end (110) to a tip (112). An attachment root (108) is at the inboard end. The blade comprises an aluminum alloy substrate (102) and a coating at the tip (130). The coating (130) comprises an anodic layer (160) atop the substrate and an aluminum oxide layer (162) atop the anodic layer.
Abstract:
An edge seal for preventing airflow through a space between a fan platform and an adjacent airfoil in a gas turbine engine may include a bonding segment being bondable to the fan platform. A sealing flap converges with the bonding segment so that the sealing flap is operatively contactable with the adjacent airfoil. A bumper rib protrudes from the bonding segment so that the bumper rib is bondable to the fan platform.
Abstract:
An annular bushing includes an annular cylindrical portion with a flange that defines a fastener aperture along an axis. A multiple of spacers extend from an outer surface of the annular cylindrical portion and the flange. The multiple of spacers are operable to control a bond line thickness.
