Abstract

A shroud (20) for a compressor stator includes shroud segments (22) extending circumferentially around an axis (11) along portions of a circumference of the shroud (20). At least one of the shroud segments (22) extends from a first lateral edge to a second lateral edge. The shroud segment (22) has an inner face oriented toward the axis (11) and an opposed outer face oriented away from the axis (11). At least one opening extends from the inner face to the outer face for receiving a vane of the compressor. A tab protrudes circumferentially from the second lateral edge and away from the first lateral edge. A slot extends circumferentially from the first lateral edge toward the second lateral edge. The tab is matingly received within a slot of an adjacent one of the shroud segments (22).
