Abstract

A rotating seal (401) rotatable about a rotational axis (A) is provided. The rotating seal (401) includes a body (410) having a first surface (411) disposable to face the rotational axis (A) and a second surface (412) disposable to contact with a stationary element (230). The body (410) defines a cooling channel (420) including one or more entrance channels (430) respectively extending from the first surface (411), one or more exit channels (440) and a plenum (450). The plenum (450) extends circumferentially through the body (410) and has a hot side (451) adjacent to the second surface (412). The plenum (450) is fluidly interposed between the one or more entrance channels (430) and the one or more exit channels (440) whereby fluid exiting the one or more entrance channels (430) and entering the plenum (450) impinges against the hot side (451). A method of manufacturing the rotating seal (401) includes the additive manufacturing of the seal body (410).
