Passage obstruction for improved inlet coolant filling

摘要

A cooled gas turbine engine component (30) includes a cooling passage (32), one or more cooling inlet apertures (36) in flow communication with a coolant supply and a first end of the cooling passage (32), and a coolant flow obstruction (40) inside the cooling passage (32) between the one or more cooling inlet apertures (36) and a second end of the cooling passage (32) and configured to direct a portion of coolant from the one or more cooling inlet apertures (36) toward the first end of the cooling passage (32).
