Abstract: An airfoil for a gas turbine engine according to an example of the present disclosure includes, among other things, an airfoil section extending between a leading edge and a trailing edge in a chordwise direction and extending between a tip portion and a root section in a spanwise direction. The airfoil section defines pressure and suction sides separated in a thickness direction. A sheath extends in the spanwise direction along at least one of the pressure and suction sides of the airfoil section. A tip cap extends in the chordwise direction along the at least one of the pressure and suction sides. The sheath includes a first set of interface members. The tip cap includes a second set of interface members interleaved with the first set of interface members to establish at least one joint along an external surface of the at least one of the pressure and suction sides. A method of assembly for an airfoil is also disclosed.

Abstract: A mask includes a masking body including at least a first edge, a second edge, and a third edge, together defining at least part of a perimeter around a first surface and a second opposing surface. A standoff arrangement includes at least one projection extending from the first or second surface of the masking body. The at least one projection is connected to the first or second surface at a location inward from the at least one edge of the masking body, thereby defining a first overhanging portion of the masking body overhanging the at least one projection proximate to the at least one edge of the masking body.

Abstract: An airfoil includes an airfoil body that extends between a leading edge and a trailing edge, a suction side and a pressure side, and a first end and a second end, a fitting located at one of the first end or the second end, the fitting including a body portion, a fillet portion, and a neck portion joining the body portion and the neck portion, the neck portion including a shelf, a fastener through the airfoil body, and a shroud having a complementary shape to the shelf such that the shroud nests in the shelf.
