Patent number: 9546567Abstract: A system is provided including a turbine exhaust section. The turbine exhaust section includes an exhaust flow path. The turbine exhaust section also includes an outer structure having an outer casing, an outer exhaust wall disposed along the exhaust flow path, and an outer cavity disposed between the outer exhaust wall and the outer casing. The turbine exhaust section further includes an inner structure having an inner exhaust wall disposed along the exhaust flow path, an inner cavity disposed between the inner exhaust wall and an inner casing, and a bearing cavity disposed between the inner casing and a bearing housing. In addition, the turbine exhaust section includes a strut extending between the outer structure and the inner structure. The strut includes a first flow passage configured to flow a fluid from the inner cavity to the outer cavity.Type: GrantFiled: October 2, 2012Date of Patent: January 17, 2017Assignee: General Electric CompanyInventors: Ravi Shankar Venkata Kasibhotla, Piotr Edward Kobek, Srinivasarao Pakkala, Radu Ioan Danescu, David Martin Johnson

Patent number: 8979477Abstract: A system is provided with a turbine exhaust strut configured to provide a bi-directional airflow. The turbine exhaust strut includes a first portion having a first flow passage configured to flow a fluid in a first direction between inner and outer exhaust walls of a turbine exhaust section, and a second portion having a second flow passage configured to flow the fluid in a second direction between the inner and outer exhaust walls of the turbine exhaust section. Furthermore, the first and second directions are opposite from one another.Type: GrantFiled: March 9, 2011Date of Patent: March 17, 2015Assignee: General Electric CompanyInventors: David Martin Johnson, Radu Ioan Danescu, Srinivasarao Pakkala, Piotr Edward Kobek

Patent number: 8573078Abstract: A system for positioning a sensor through an inner barrier and an outer barrier includes a first collar configured for engagement with the inner or outer barriers, a collapsible coupling, and a sensor support connected to the collapsible coupling. The collapsible coupling or the sensor support is in sealing engagement with the first collar, and the first collar, collapsible coupling, and sensor support define a passage therethrough. A method for positioning a sensor includes engaging a first collar to at least one of the inner barrier or the outer barrier and inserting a sensor support connected to a collapsible coupling through the outer barrier. The method further includes connecting the sensor support or the collapsible coupling to the first collar and inserting the sensor through the sensor support.Type: GrantFiled: November 23, 2010Date of Patent: November 5, 2013Assignee: General Electric CompanyInventors: Peter Ping-Liang Sue, Holly Renae Davis, Tomasz Ryszard Szmigiel, Piotr Edward Kobek
