ABSTRACT:
A stationary annular rotor blade tip seal assembly includes an annular support extending continuously circumferentially around and radially outwardly of the tips of a plurality of blades on a turbine rotor. A seal mount ring includes a plural number of seal mount segments retained axially of the annular support and having circumferential ends on each of the adjacent segments spaced apart to receive a retaining spring and seal strip. A low density seal insert is mounted on each of the seal mount segments and is spring biased into seated engagement with each of the seal mount segments by the retaining spring with the seal strip closing a gap between each of the low density seal inserts.
