SEALING SYSTEMS

A sealing system (100) for a turbomachine includes an annular seal (104) defining a centerline axis (A) and an inner diameter sealing surface (110). The sealing system also includes a turbomachine component radially inboard of the annular seal having a sealing surface defined on an outer diameter su...

More Information
Summary:A sealing system (100) for a turbomachine includes an annular seal (104) defining a centerline axis (A) and an inner diameter sealing surface (110). The sealing system also includes a turbomachine component radially inboard of the annular seal having a sealing surface defined on an outer diameter surface (114). The sealing surface of the turbomachine component has a radius of curvature configured to be non-concentric with respect to the inner diameter sealing surface of the annular seal in a cold sate. The radius of curvature of the sealing surface is configured to be concentric with respect to the inner diameter sealing surface of the annular seal in a hot state.
