Removable cowl for gas turbine combustor

摘要

A cowl (20) for directing flow of air entering an annular combustor assembly (22) of a gas turbine engine and which is removable from the combustor without disassembling the combustor. The cowl (20) is annular in shape and has a plurality of circumferentially spaced fastener holes (70) for receiving fasteners (28) which commonly connect and align the cowl (20), an annular dome (36), and a liner (34). At least one notch (72) is in the cowl (20), each notch being sized sufficiently larger than a corresponding fastener (28) to permit the cowl (20) to be moved to or removed from an operative position while the corresponding fastener (28) remains in position for connecting the dome and liner to one another.
