摘要： A fan blade has an airfoil main body extending between a leading edge and a trailing edge. The airfoil also has suction and pressure sides. A cavity is formed into said main body, and receives a filler material. A cover closes off the cavity, and is attached to the main body, with the cover having a thickness defined in a direction perpendicular to the suction side. The main body has a spar which extends along the cavity, with a thickness of the spar at a central location between ends of the cavity which has a second thickness. A ratio of the first thickness to the second thickness is between.5 and 2. A fan rotor and a gas turbine engine are also disclosed.

摘要： A rotary blade is provided that includes a root, an airfoil, and a tip insert. The airfoil is attached to the root, and has a suction side surface, a pressure side surface, a leading edge, a trailing edge, a tip, and a slot disposed within the tip. The slot extends in a chordwise direction between the leading edge and trailing edge. The tip insert has a base end and a rub end. The base end of the tip insert is disposed within the slot. The rub end of the tip insert extends radially outward from the airfoil tip.

摘要： A fan blade comprises an airfoil portion and a sheath portion. The sheath portion has a sheath head section, a first sheath flank, and a second sheath flank, both flanks extending chordwise from the forward sheath section. The sheath portion is bonded to the airfoil portion such that the sheath head section covers the forward airfoil edge, defining a blade leading edge. The first sheath flank covers a portion of the first airfoil surface proximate the airfoil forward edge, jointly defining a blade suction surface. The second sheath flank covers a portion of the second airfoil surface proximate the airfoil forward edge, jointly defining a blade pressure surface. The first metallic material is an aluminum alloy containing between about 0.5 wt% and about 3.0 wt% of lithium.
