Systems, methods, and apparatus for a turbine interstage rim seal

摘要

Certain embodiments of the invention may include systems, methods, and apparatus for providing a turbine interstage rim seal. According to an example embodiment of the invention, a method is provided for sealing a turbine rotor-bucket interface. The method can include linking a first portion of one or more rim seal segments with one or more flow path seal segments. The method includes rotating the one or more rim seal segments, upon application of centrifugal force, to displace a second portion of the one or more rim seal segments; and sealing at least a portion of a gap between a rotor and a bucket associated with a turbine with at least one or more rotated rim seal segments.

主权项

1. A method for sealing a turbine rotor-bucket interface, the method comprising:
linking a first portion of one or more rim seal segments with one or more flow path seal segments; upon application of centrifugal force, pivoting a first portion of the one or more rim seal segments within a rim seal channel and translating a second portion of the one or more rim seal segments within the rim seal channel to displace a third portion of the one or more rim seal segments; and sealing at least a portion of a gap between a rotor and a bucket associated with a turbine with at least one or more rotated rim seal segments.
