ABSTRACT:
A system for sealing the peripheries of rotating rotor blades is disclosed in which a seal ring is mounted to the stationary casing adjacent the blade tips. The inner surface of the seal ring defines a plurality of grooves, each groove having a generally triangular shaped cross section. The longitudinal and radial dimensions of the grooves may be identical, or may vary along the longitudinal direction of the seal ring.
