Patent ID: 7494317

Claim:
An attachment system comprising: a vane carrier having an inner peripheral surface; a forward isolation ring and an aft isolation ring spaced axially downstream of the forward isolation ring, wherein the isolation rings are attached to the vane carrier such that the isolation rings extend substantially circumferentially about and substantially radially inward from the inner peripheral surface of the vane carrier; a ring seal having a radially outermost periphery and a radially innermost periphery, the ring seal having a plurality of substantially circumferentially spaced slots, wherein the slots extend substantially axially through the ring seal, wherein each slot opens to a surface of the radially outermost periphery of the ring seal and extends radially inward therefrom; and a plurality of pins, wherein each of the plurality of pins substantially passes through a respective slot in the ring seal and operatively engages the forward and aft isolation rings, whereby the ring seal is structurally connected to the vane carrier by the isolation rings and the pins so that axial and circumferential movement of the ring seal is substantially restricted while relative radial movement between the ring seal and the vane carrier is permitted.
