An attachment system comprising: a vane carrier (40), wherein the vane carrier has an inner peripheral surface; a forward isolation ring (44) and an aft isolation ring (46) spaced axially downstream of the forward isolation ring (44), wherein the isolation rings are attached to the vane carrier such that the isolation rings extend substantially circumferentially about and radially inward from the inner peripheral surface of the vane carrier, wherein a plurality of protrusions (90) extend substantially axially from and substantially circumferentially about each of the isolation rings; a ring seal (52) enclosed within the vane carrier, the ring seal having an axial forward side and an axial aft side, and wherein a plurality of protrusions extend substantially axially from and substantially circumferentially about each axial side of the ring seal, wherein the ring seal is operatively connected to the vane carrier such that the protrusions on the axial forward side of the ring seal substantially matingly engage the protrusions on the forward isolation ring, and wherein the protrusions on the axial aft side of the ring seal substantially matingly engage the protrusions on the aft isolation ring, whereby the vane carrier and the ring seal move at least partially independent of each other in the radial direction. |
