Abstract: FAN BLADE TIP AS A CUTTING TOOL An airfoil for a gas turbine engine is disclosed. The airfoil may include a first side, and a second side opposite the first side. The first side and the second side may extend axially from a leading edge to a trailing edge and radially from a base to a tip. The tip may include an oblique surface between the first side and the second side. [No suitable figure]

Abstract: An airfoil (36) for a gas turbine engine (20) is disclosed. The airfoil (36) may include a first side (48), and a second side (50) opposite the first side (48). The first side (48) and the second side (50) may extend axially from a leading edge (54) to a trailing edge (56) and radially from a base (52) to a tip (46). The tip (46) may include an oblique surface (60) between the first side (48) and the second side (50).

Abstract: METHOD FOR SECURING A SHEATH TO A BLADEA method for bonding a sheath made of a first metallic material to an airfoil made of a second metallic material includes treating the bonding surface of the airfoil; treating the bonding surface of the sheath; placing an adhesive between the bonding surfaces of the airfoil and the sheath; and pressing the airfoil and sheath together so that the adhesive bonds the sheath to the airfoil.Fig. 2
