Publication number: 20150040567Abstract: A turbine assembly is disclosed herein. The turbine assembly may include a rotor with at least one bucket extending radially therefrom. The turbine assembly also may include a stator assembly positioned adjacent to the at least one bucket. Moreover, the turbine assembly may include a seal assembly. The seal assembly may include a first flange extending in a substantially axial direction from the at least one bucket. The seal assembly also may include a second flange extending from the stator assembly in the substantially axial direction opposite the first flange. The second flange may include at least one protuberance projecting towards the first flange.Type: ApplicationFiled: August 8, 2013Publication date: February 12, 2015Applicant: General Electric CompanyInventors: Guoqiang Lu, Xiaoqing Zheng, Jong Youn Pak

Publication number: 20120134782Abstract: A method for assembling a rotary machine includes providing a first rotatable element. The method also includes coupling a second rotatable element to the first rotatable element. The first rotatable element and the second rotatable element at least partially define a cavity therein and at least one conduit extending substantially axially therebetween. Further, the method includes coupling a purge device including at least one radial channel defined therein and extending to the first rotatable element and to the second rotatable element such that the at least one radial channel is coupled in flow communication with the cavity and with the at least one axial conduit.Type: ApplicationFiled: November 30, 2010Publication date: May 31, 2012Inventors: Creston Lewis Dempsey, Seung-Woo Choi, Raymond Joseph Lecuyer, Matthew Ryan Ferslew, Jong Youn Pak, Josef Scott Cummins
