RING SEAL ATTACHMENT SYSTEM

摘要

Aspects of the invention relate to a system for attaching a ring seal (52) to a vane carrier (40) in a turbine engine such that the ring seal (52) can radially expand and contract at least partially independently of the vane carrier (40). The system can also be configured to substantially restrict axial and/or circumferential movement of the ring seal (52). In one embodiment, the ring seal (52) can include a plurality of radial slots (70) circumferentially spaced about the ring seal (52). A pin (76) can extend substantially through each of the slots (70) and into operative engagement with isolation rings (44, 46), which are connected to the vane carrier (40). In another embodiment, the ring seal (52) and the isolation rings (44, 46) can include a series of axially-extending protrusions (90, 92) extending substantially circumferentially about each component. The protrusions (92) on the ring seal (52) can substantially matingly engage the protrusions (90) on the isolation rings (44, 46). The protrusions (90, 92) can be configured as a Hirth coupling (93)
