Abstract
A low-pressure (LP) turbine includes an LP shaft, one or more stages of LP turbine stator vanes and LP turbine rotor blades, and one or more interstage seals. The LP turbine rotor blades are coupled to, and rotate with, the LP shaft. The one or more interstage seals are disposed between the one or more stages. The one or more interstage seals each includes a seal disk that extends radially inward of the LP turbine stator vanes. Each seal disk includes an outer shell that supports one or more seal teeth, and the outer shell rotates as the LP shaft rotates.
