A shroud for a rotor assembly disposed within a case is provided. The shroud includes suspension apparatus, a control ring, and a blade outer air seal. The suspension apparatus is disposed between the control ring and the case. The control ring includes a body and a first attachment mechanism. The blade outer air seal includes a second attachment mechanism. The first and second attachment mechanisms cooperate to secure the blade outer air seal to the control ring.

A gas turbine engine liner assembly is disclosed having uniformly spaced rows of cooling orifices oriented perpendicular to the combustion gas flow of the engine. The orifices within each row are spaced equidistant from adjacent orifices within the same row, thereby providing a uniform, uninterrupted pattern of cooling orifices over the hot side of the liner. The liner is secured to a component of the gas turbine engine by a plurality of fasteners which are secured to the liner without affecting the uniform pattern of the cooling orifices.

A thermal relief slot is formed by including a lateral slot in each of three overlying sheet metal sheets with the upper and lower slots being in overlying position and the middle slot being axially spaced therefrom and the three sheets being bonded into an integral sheet metal sheet assembly except for the area extending over the relief slots. The edge of the upper and/or lower outer edges of adjacent the relief slots may be chamfered to prevent fraying of the edges. A two sheet assembly includes the relief slots axially spaced and two sheet metal sheets are bonded except for the area including and extending between the two relief slots.

The neck portion of a rotor blade includes an annular, axially projecting segment integral with the neck and having side edges abutting corresponding segments of adjacent blades to form a segmented annular ring which cooperates with static structure to define an interstage annular seal. Each blade also includes an air dam extending laterally from each side of the root neck and extending radially between the blade platform and the annular seal segment. The air dams of adjacent blades also abut each other to define an annular seal which prevents the axial flow of air across the rotor stage under the blade platforms between the blade root necks. In a preferred embodiment thin strips of silicone rubber are used to seal any gaps between the abutting edges of adjacent blades.
