Abstract
A seal assembly for a gas turbine engine defining a central axis extending along an axial direction and including a rotating shaft extending at least partially along the axial direction. The seal assembly includes a first component coupled to a fixed structure or drivingly coupled to the rotating shaft. The seal assembly further includes a rotating component drivingly coupled to the rotating shaft of the gas turbine engine. Additionally, the first component and rotating component define an annular gap therebetween. The seal assembly also includes one or more flanges extending from the stationary component, the rotating component, or both. The flange(s) include a base and an external surface extending into the annular gap from the base to a tip. Additionally, the flange(s) defines an inlet port on the external surface fluidly coupled to an outlet port at the tip. As such, the flange(s) forms a seal within the annular gap.
