Abstract
A shaft seal reduces leakage between a rotating shaft such as a rotor and a stator. The shaft seal or shingle seal includes a plurality of compliant-plate members attached to the stator in facing relation. The compliant-plate members define a sealing ring between the stator and the rotating shaft. Each of the compliant-plate members includes a plurality of shingles, where adjacent compliant-plate members are disposed relative to each other such that the shingles are at least partially staggered in a direction of axial leakage.
