A wing shroud has a body including a side portion having a side inner surface, a side abutment surface, a side outer surface, and a side rear surface, a floor portion having a floor upper surface, a floor lower surface, a floor front surface, a floor outer surface, and a floor rear surface, and an attachment recess defined by a plurality of inward surfaces on the side and floor portions. The body also has a leading edge extending between the side inner surface, the side outer surface, the floor front surface, the floor upper surface, and the floor outer surface, and including an upper end, a transition portion, a lower curved portion, and a lower end.

Wing shroud

A heel shroud includes a bottom leg, and a side leg extending orthogonally from the bottom leg, forming an interior corner with the bottom leg. The heel shroud defines a first lateral surface, a second lateral surface, and the bottom leg includes a curved interior surface extending from the first lateral surface to the second lateral surface at least partially forming the interior corner. The first lateral surface defines a first wear indicator or a stress reduction geometry that is disposed at the interior corner.

Heel shroud having stress concentration reduction geometry and enhanced durability

A heel shroud includes a bottom leg, and a side leg extending orthogonally from the bottom leg, forming an interior corner with the bottom leg. The heel shroud defines a first lateral surface, a second lateral surface, and the bottom leg includes a curved interior surface extending from the first lateral surface to the second lateral surface at least partially forming the interior corner. The first lateral surface defines a stress reduction geometry positioned at the interior corner, or includes a wear member that is attached to the side leg, or the bottom leg.
