CMC shroud support system

Abstract

A shroud and a shroud hanger are provided wherein at least the shroud is formed of ceramic matrix composite material. The shroud and hanger extend in a circumferential direction. A generally C-shaped clip extends radially to retain the hanger and shroud together.

Description

technical field [0001] The disclosed embodiments generally relate to shrouds for gas turbine engines. More specifically, but not by way of limitation, the presented embodiments relate to a ceramic matrix composite (CMC) shroud support system for use in a gas turbine engine that includes a clamping structure for attaching a CMC shroud. Background technique [0002] A typical gas turbine engine generally has a front end and an aft end with its several cores or propulsion members positioned axially therebetween. An air inlet or air intake is located at the front end of the engine. Moving towards the rear end in sequence, the intake is followed by the compressor, combustor and turbine. It will be readily apparent to those skilled in the art that additional components may also be included in the engine such as, for example, low and high pressure compressors and low and high pressure turbines. However, this is not an exhaustive list. The engine also typically has an inner shaf...

Problems solved by technology

[0007] Alternatively, when this radial movement is not properly restricted in the radially outward opposite direction, the shroud can move too far from the adjacent blade tip, allowing air leakage and reducing efficiency
