TRAILING EDGE DUCT FOR COMBUSTORS WITH COOLING FEATURES

摘要

A combustor has a trailing edge duct (110) that has cooling features located at various locations. The cooling features comprise pockets (125) that have pocket channels (127) which extend from the pockets (125) to seam locations on the main duct portion (112). Additional cooling features comprise slots (132) located proximate to the pockets (125) and the trim line (131) at a distal end of the main duct portion (112). In other embodiments, cooling channels (136a, 136b, 136c) are formed on the mating surfaces (135) of the extension flange (115). Further in other embodiments, cooling features may be found in the trailing edge (120) of the trailing edge duct (110).
