US 6,884,026 B2 · Turbine engine shroud assembly including axially floating shroud segment

Abstract

At least one shroud segment, floating axially independently of adjacent turbine engine shroud assembly members, includes a segment body comprising a radially outer surface and a radially outwardly projecting segment support that includes an axial support wall surface therein. The assembly includes a shroud hanger in axial juxtaposition with the segment support, and at least one axial support projection from the shroud hanger into the segment support at the support wall surface. The support projection supports the shroud segment releasably at the support wall surface sufficiently to enable relative axial movement of the shroud segment on the support projection independently of the shroud hanger and adjacent engine members.

Dependent claims

A turbine engine shroud segment for assembly circumferentially about an axial flow engine axis, separate and spaced apart from any blading member, the shroud segment comprising a shroud segment body including a radially inner surface arcuate at least circumferentially, a radially outer surface, and at least one shroud segment support integral with the shroud segment body for carrying the shroud segment body, the segment support projecting generally radially outwardly from the shroud segment body radially outer surface, wherein:

the shroud segment is separate and spaced apart from any blading member;
the radially inner surface defines a part of a turbine engine flowpath boundary over rotating blading members;
and,
the shroud segment support includes therein a support wall surface extending generally axially into and at least partially through the segment support.

1 more element

A turbine engine shroud assembly comprising at least one shroud segment floating axially independently of other engine members disposed in adjacent juxtaposition with the shroud segment in which:

the segment includes therein a shroud segment support wall surface extending generally axially into and at least partially through the shroud;
the shroud assembly includes a shroud hanger disposed in axial juxtaposition with the shroud segment, the shroud hanger including at least one support projection secured with the shroud hanger and extending generally axially from the shroud hanger into the shroud segment at the shroud segment support wall surface, the projection supporting the shroud segment releasably at the shroud segment support wall surface within the shroud segment, the shroud segment being movable axially on the projection independently of the shroud hanger and other engine members in adjacent juxtaposition with the shroud segment.
