SEAL USABLE BETWEEN A TRANSITION AND A TURBINE VANE ASSEMBLY IN A TURBINE ENGINE

摘要

A seal (10) usable to seal a transition (12) in a can-annular combustion system (14) of a turbine engine 916) to a turbine vane assembly (18) to direct exhaust gases through the turbine vane assembly (18) is disclosed. The seal (10) may be formed from an elongated body (20) extending at least partially circumferentially and one or more hot lips (22) extending axially from the elongated body (20). One or more cold lips (24) may be coupled to the elongated body (20) radially inward of the hot lip (22) and extending axially from the elongated body (20) to form a receiving cavity (26) between the hot lip (22) and the cold lip (24). The cold lip (24) may be formed from a resilient material capable of enduring contact with an adjacent row one vane rail (28). In at least one embodiment, the cold lip (24) may be formed from a different material than a material used to form the elongated body (20) and the hot lip (22).
