摘要：A turbine bucket tip clearance control system includes a rotor assembly havinga rotor supporting a plurality of axially spaced wheels, each wheel mounting an annularrow of buckets, the annular row of buckets on at least one of the plurality of axially-
spaced wheels having a radially outer tip shroud provided with at least one seal tooth. Astator assembly includes a radially inwardly facing, axially-stepped surface, formed withradially inner and outer seal surfaces connected by a shoulder. The stator assembly androtor assembly are moveable axially relative to each other, enabling selective positioningof the at least one seal tooth radially opposite one of the radially inner and outer sealsurfaces to thereby selectively alter a clearance gap between the at least one seal toothand the radially inward facing axially-stepped surface.
