    Abstract: A ring seal assembly includes a first ring seal that is symmetrical with respect to a radially extending plane. A second ring seal is separated axially from the first ring seal by a spring. The second ring seal includes a first inner circumferential surface. An interference feature extends radially inward from the first inner circumferential surface to a second inner circumferential surface.

    Abstract: A main shaft bearing compartment seal system is described herein. The modified ring groove geometry creates two distinct cavities or steps for a piston ring and a wave spring. This concept provides a separate groove cavity for the spring independent of the fool-proofing and clearance cavity. This modified ring groove geometry increases first face coverage and reduces exposure risk for eccentricity of wave spring to piston ring, to avoid potential disengagement and improve function and performance of the seal assembly and engine.

    Abstract: A seal assembly for a gas turbine engine, may be manufactured in two pieces, the first piece is a seal plate with a cavity around its inner wall and the second piece is a sleeve that mounts in the cavity of the seal plate. The sleeve may have oil distribution channels that deliver oil to subsequent components and apertures that deliver oil to the seal plate. The volume of oil delivered to the seal plate can be set by the number of apertures and related radial holes in the sleeve. Because the sleeve delivers oil through the apertures and radial holes to an annulus in the cavity of the seal plate, cooling bores in the seal plate need only be drilled into the annulus and the number of cooling bores can be independent of the number of radial holes in the sleeve.

    Abstract: A seal includes a seal runner, at least one seal ring, and a seal housing. The runner extends in an axial direction to a runner end face that faces a bearing. The ring is fixed to a static structure and has an inner surface engaging the seal runner and a first face that faces the bearing. The seal housing is fixed to the static structure and includes a first portion extending in an axial direction from the first face of the seal ring to a housing face that faces the bearing. The first portion has a first length extending from the first face of the seal ring to the housing face. The seal runner has a first runner portion with a second length that extends from the first face of the seal ring to the runner end face. The second length is at least 35% longer than the first length.

    Abstract: A bearing compartment seal for a gas turbine engine includes at least one seal ring defining an axis and having a radially inward facing sealing surface and a seal runner having a support constructed of a first material and an interface portion constructed of a second material. The interface portion includes a radially outward facing surface. A first coefficient of thermal expansion of the second material is at most approximately equal to a second coefficient of thermal expansion of the at least one seal ring.

    Abstract: A ring seal assembly is provided. The ring seal assembly may comprise an air side ring seal and an oil side ring seal. The air side ring seal may have one or more axial and radial grooves. The oil side ring seal may also have one or more axial and radial grooves, and may have circumferential slots in fluid communication with one or more of the grooves. The oil side ring seal may have an extended leg protruding towards the air side ring seal. The extended leg and a forward outer surface of the oil side ring seal and an aft outer surface of the air side ring seal may define a spring cavity.

    Abstract: A ring seal in a gas turbine engine includes a ring seal body, an axial sealing dam, a radial sealing dam, and at least one bleed slot. The ring seal body is annular in shape and has a first axial side, a second axial side, a radially outer side, and a radially inner side. The axial sealing dam is on the first axial side and is configured to provide a first sealing surface with a first component. The radial sealing dam is on the radially outer side and is configured to provide a second sealing surface with a second component radially outward from the radially outer side. The at least one bleed slot is on the second axial side and configured to allow fluid to pass through when the ring seal is incorrectly oriented such that the at least one bleed slot is adjacent to the first component.
