摘要

Disclosed herein is a seal assembly for a rotary machine having a plurality of arcuate segments and at least one seal. The plurality of arcuate segments are arrayed in an annulus and have butt joints, each of the arcuate segments has a radially outermost surface and a downstream face. The at least one seal is arranged to minimize leakage through the butt joints.
