ABSTRACT:
A slidable seal is disposed in one end of each stationary arcuate shroud segment in a gas turbine. The seal is forced by a spring across a gap between adjacent shroud segments, to abut against an end of an adjacent shroud segment. The slidable seal helps control fluid leakage in both the axial and the radial direction.
