Abstract
A shroud segment for a gas turbine engine includes a rail engaged with adjacent support structure to retain the segment and to provide sealing between the segment and the adjacent structure. Various construction details are disclosed which provide an effective sealing and retaining feature that permits differing thermal growth between the segment and the support structure. In a particular embodiment, a shroud segment includes a rail along a forward edge. The rail is engaged with a recess in the support structure to retain the segment and with a band which positions the segment and seals the forward edge.
