Abstract

An annular seal includes an annular outer casing, a plurality of seal segments, and a plurality of spring components. The plurality of seal segments is coupled to the annular outer casing to cumulatively form an annular sealing surface, the annular sealing surface is configured to face a rotating structure to inhibit fluid leakage between the rotating structure and the annular sealing surface, and each seal segment of the plurality of seal segments is configured for independent radial movement relative to other seal segments of the plurality of seal segments. In various embodiments, the plurality of spring components are configured to bias the plurality of seal segments relative to the radial movement.
