Abstract
A seal for an assembly containing a ceramic matrix composite (CMC) vane disposed in contact with a tangential onboard injector or an inner air seal outer diameter, comprising at least one seal disposed within a groove formed at a sealing interface between the CMC vane and the tangential onboard injector or the inner air seal outer diameter, wherein the groove comprises an upper surface of an upper sealing interface surface formed within an inner diameter platform of the CMC vane and a lower surface of a lower sealing interface surface, and opposite the upper surface, formed within the tangential onboard injector or the inner air seal outer diameter.
Claims20
A seal for an assembly containing a ceramic matrix composite (CMC) vane disposed in contact with a tangential onboard injector or an outer diameter of an inner air seal, comprising:
- at least one seal disposed within a groove formed at a sealing interface between the CMC vane and the tangential onboard injector or the outer diameter inner air seal,
- wherein the groove comprises an upper surface of an upper sealing interface surface formed within an inner diameter platform of the CMC vane and a lower surface of a lower sealing interface surface, and opposite the upper surface, formed within the tangential onboard injector or the inner air seal outer diameter,
- wherein the seal comprises a two-piece seal having an aft seal segment including one or more crimped portions and a fore seal segment, wherein the fore seal segment receives the crimped portions and retains the aft seal segment.

An assembly for a gas turbine engine, comprising:
- a ceramic matrix composite vane having a ceramic matrix composite vane inner diameter platform including an upper sealing interface surface with an upper surface of a groove;
- a tangential onboard injector including a lower sealing interface surface with a lower surface of the groove, or
- an inner air seal outer diameter including a lower sealing interface surface with a lower surface of the groove,
- the CMC vane inner diameter platform and either the tangential onboard injector or the inner air seal outer diameter are disposed in contact to form an interface comprising the upper sealing interface surface and the lower sealing interface surface;
- and
- a seal disposed within the groove formed by the upper surface and the lower surface,
- wherein the seal comprises a two-piece seal having an aft seal segment including one or more crimped portions and a fore seal segment, wherein the fore seal segment receives the crimped portions and retains the aft seal segment.

A method of installing a seal in an assembly for a gas turbine engine, comprising the steps of:
- providing a ceramic matrix composite vane having a ceramic matrix composite vane inner diameter platform including an upper sealing interface surface with an upper surface of a groove;
- providing either a tangential onboard injector including a lower sealing interface surface with a lower surface of the groove or an inner air seal outer diameter including a lower sealing interface surface with a lower surface of the groove;
- placing a seal within either the upper surface or the lower surface of the groove;
- and
- disposing the upper sealing interface surface in contact with the lower sealing interface surface,
- wherein the seal comprises a two-piece seal having an aft seal segment including one or more crimped portions and a fore seal segment, wherein the fore seal segment receives the crimped portions and retains the aft seal segment.
