Abstract:
Aspects of the disclosure are directed to a system comprising: a first seal that includes a notch configured to avoid an adjacent seal plate radius edge and a first protrusion, and a second seal that is notch-free with respect to an inner diameter sealing face and includes a second protrusion, wherein the first protrusion and the second protrusion are configured to at least partially overlap with one another in at least one of an axial direction or a radial direction with respect to an engine centerline.
Abstract:
A seal assembly with an axis is provided that includes a rotor and a seal element that is connected to a stator with an anti-rotation element. The seal element includes a first element surface, a second element surface and an annular notch. The first element surface axially engages the stator. The second element surface radially engages the rotor. The notch extends into the seal element between the first and the second element surfaces. The stator radially overlaps a portion of the notch.
Abstract:
A system is provided associated with an engine of an aircraft. The system includes a ring, a runner and at least one radially-oriented hole associated with the runner that is configured to supply oil to an interface between the runner and the ring. The at least one hole is contained within an axial projection of the ring.

Abstract:
A carbon seal assembly may comprise a seal support, a seal housing coupled to the seal support, and a carbon seal adjacent an aft portion of the seal housing. The carbon seal may comprise a nose defined by an axial surface of the carbon seal, a first radial surface of the carbon seal, and a second radial surface of the carbon seal radially inward of the first radial surface. The first radial surface and the second radial surface may extend forward from the axial surface. A first axial length of the first radial surface may be greater than a second axial length of the second radial surface.
Abstract:
A seal assembly is provided that extends along an axial centerline, and includes a rotor seal element that engages with a stator seal element. The rotor seal element extends radially between an inner element side and an outer element side, and includes a channel, a plurality of first passages and a plurality of second passages. The channel extends radially into the rotor seal element from the inner element side. The first and the second passages are fluidly coupled with the channel. Each of the first passages extends radially through the rotor seal element to a respective first passage outlet. Each of the second passages extends axially through the rotor seal element to a respective second passage outlet.

Abstract:
Aspects of the disclosure are directed to an apparatus comprising a first section, and a second section coupled to the first section, wherein the second section is configured to substantially coincide with an edge of a seal and includes a pre-tapered edge.
