Abstract
A stator rim structure for a gas turbine engine comprises a stator having an end wall and a discourager defining a channel therebetween. The end wall is adjacent to a hot gas flow and the discourager is adjacent to a purge flow. A rotor has an angel wing extending into the channel. At least one supply passage is disposed within the stator and extends through the discourager and at least one aperture fluidly couples the supply passage with the channel. A flow of cooling air is fed from the supply passage into the aperture and into the channel to form a fluidic dam discouraging ingestion of the hot gas flow.
