Abstract
An inner turbine seal is formed of a full annular vane platform structure (32) and a full annulus seal land structure (60). These two structures are splined together (48, 50, 64) and piston ring (70) seals against leakage between the two structures. Radial differential growth between the structures is permitted. Vane platform structure (32) may therefore be designed to minimize stresses in the vane area (26, 28) while seal land structure (60) may be designed to minimize leakage through knife edge seals (22, 62).
