Abstract:
There are provided systems and processes for attaching a non-metal component comprising a ceramic matrix composite material, such as a transition duct, to a metal component, such as a mating flange of an individual exit piece for a gas turbine. The systems and processes accommodate the differences in the thermal expansion rate of the components, as well as provide connection structures which avoids interlaminar shear of the ceramic matrix composite material by loading the ceramic matrix composite material in compression and eliminating bending forces on the ceramic matrix composite material.

Claim (Index 1):
An attachment system for attaching a non-metal component to a metal component comprising:\n a non-metal component including a ceramic matrix composite material, wherein the non-metal component comprises a transition duct for a gas turbine engine; a metal component, wherein the metal component comprises a metallic mating flange for an individual exit piece of the gas turbine engine; a first segment having a base portion arranged to abut a surface of the non-metal component and a first extent extending radially from the base portion, the first extent arranged to abut a surface of the metal component; a second segment comprising a locking flange, wherein the first extent of the first segment is arranged between the locking flange of the second segment and the metal component; a first fastening device arranged to secure the base portion to the non-metal component; a second fastening device arranged to secure the first extent between the locking flange and the metal component; and a radial gap disposed between the first extent and the locking flange to accommodate different rates of thermal expansion between the non-metal and metal components.
