: “ SEAL ASSEMBLY FOR TURBINE, BUCKET/TURBINE INCLUDING SAME, METHOD FOR SEALING INTERFACE BETWEEN ROTATING AND STATIONARY COMPONENTS OF A TURBINE”
Application 2212/DEL/2004 published 2006-08-18, filed 2004-11-05
A rotary machine (10) includes a rotatable rotor (12, 12; 48), buckets (14, 14; 56) radially mounted on and spaced apart about the rotor, a stationary stator/casing (16, 16) disposed about and radially outward from the rotor defining an annular gap (18) between the casing and tips (14a, 14a’) of the buckets, and an abrabable seal member (20, 20’) provided to the bucket tip portions and disposed within the annular gap such that during differential growth of the rotor and buckets relative to the casing the seal member abrades in response to contact with a base seal member provided to the stator casing. Thereby, clearance between the stator casing and bucket tips is minimized between the moving bucket tips with the stator casing.
