Mantelringsegment, Herstellungsverfahren eines Mantelringsegments, sowie Mantelringanordnung für ein Turbinentriebwerk

摘要

A turbine engine shroud segment (10) comprises a segment body (12) including a radially inner surface (22) arcuate at least circumferentially, a radially outer surface (24), and a plurality of axially and circumferentially spaced apart edge surfaces (26,27/28) connected with and between the inner (22) and outer (24) surfaces. For carrying the segment body (12), the segment (10) includes a projection (14), integral with and projecting generally radially outwardly from the body (12). The projection (14) comprises a projection head (30) spaced apart from the body radially outer surface (24) and a projection transition portion (32), having a transition surface (34), integral with both the projection head (30) and the body radially outer surface (24). In a turbine engine shroud assembly, a plurality of such shroud segments (10) are assembled circumferentially (16) with a shroud hanger (40) that carries the segments (10) in a hanger cavity (46). The cavity (46) is defined at least in part by radially inner opposed hook members (48) each including an end portion (50) that registers with and carries the shroud segment (10) at the projection transition surface (34).
