Abstract

A seal assembly which, among other applications, may be used for sealing fluid leakage between a steam or combustion (gas) turbine rotor and a turbine stator body. The seal assembly includes elements having a plurality of spaced seal members with slots therebetween. Each seal member is angled between a fixed end and a free end thereof, and the free ends slidably engage the rotatable component. The elements may be juxtaposed such that seal members of each element block slots of another element. A method of inhibiting fluid flow and a method of fabricating the seal assembly are also disclosed.
