Abstract

A shroud hanger assembly (30) or shroud assembly for dimensionally incompatible components is provided, wherein the assembly includes, for example, a multi-part hanger (32). A cavity (46) is formed between the components; a shroud (50) may be positioned therein, the shroud (50) being formed of a low coefficient of thermal expansion material. The hanger (32) and shroud (50) may be formed from the same material or different materials to better match thermal growth between the hanger and shroud. When the shroud (50) is positioned within the hanger opening or cavity (46), one of the front hanger portion (34) and the rear hanger portion (36) can be snugly fitted or otherwise connected to the front In the other of the hanger section (34) and the rear hanger section (36).

Description

[0001] Statement Regarding Federally Sponsored Research [0002] none. [0003] Cross-references with related literature [0004] This application claims priority to U.S. Provisional Patent Application No. 62 / 011231, entitled "ShroudHanger Assembly," filed June 12, 2014, by Jason David Shapiro et al., the disclosure of which is incorporated by reference And combined in this article. technical field [0005] Embodiments herein relate to a shroud hanger assembly for use in a gas turbine engine. More particularly, embodiments herein relate, without limitation, to shroud hanger assemblies that include structures to improve retention of the shroud therein. Background technique [0006] A gas turbine engine includes a turbine core having a high pressure compressor, combustor, and high pressure turbine ("HP") in continuous flow relationship. The core can be operated in a known manner to generate the primary gas flow. A high pressure turbine includes an annular array ("row") of...
