<P>PROBLEM TO BE SOLVED: To improve sealing performance of an interstage rim seal. <P>SOLUTION: 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 (216) of one or more rim seal segments (112) with one or more flow path seal segments (202). The method includes rotating the one or more rim seal segments (112), upon application of centrifugal force, to displace a second portion (218) of the one or more rim seal segments (112); and sealing at least a portion of a gap (302) between a rotor (108) and a bucket (102) associated with a turbine (100) with at least one or more rotated rim seal segments (112). <P>COPYRIGHT: (C)2012,JPO&INPIT |
