Abstract
An assembly to control a gap between a rotor blade and a casing in a turbine engine, the assembly including a casing having an annular casing body and a liner positioned adjacent an inner radial surface of the annular casing body, the casing being separated from a rotor blade by a gap in a radial direction. The annular casing body has a lower coefficient of thermal expansion (CTE) than that of the liner and that of the rotor blade. The liner is provided to control the gap between the rotor blade and the casing.
