摘要：A combustion duct for a gas turbine engine has a combustion liner (3 1) toreceive products of combustion, and deliver the products of combustion downstreamtoward a turbine rotor. An outer housing (22) is positioned radially outwardly of thecombustion liner (31). A flow sleeve (32) is positioned radially intermediate the outerhousing (22) and the combustion liner (31). A chamber (30) radially outwardly of the flowsleeve (32) receives cooling air. A plurality of holes (35) through the flow sleeve delivercooling air from the chamber (30) against an outer periphery of the combustion liner (31).A plurality of tabs (40) are associated with at least some of the holes (35) in the flowsleeve (32). The tabs (40) are positioned to extend radially inwardly on a downstream sideof the holes (35).
