Patent number: 8695196
Abstract: A system and associated method for disengaging a shrink coupling that secures a shaft to a drive train component, such as a gearbox, includes a reaction plate erected around the shaft at a location displaced from the shrink coupling, with the reaction plate being anchored in place relative to the shaft. A plurality of jacking devices, such as hydraulic jacks, are operationally disposed between the reaction plate and shrink coupling and spaced circumferentially around the shaft. The jacking devices have a first end engaged against the reaction plate and a second opposite end mechanically fastened to the shrink coupling. To remove the shrink coupling from the drive train component, the shrink coupling is released from its clamped state and the jacking devices are activated to exert a pulling force on the shrink coupling, which causes the shrink coupling to be pulled off of the drive train component and moved axially along the shaft to a resting position on the shaft.

Application number: 20140096530
Abstract: An air management arrangement for a late lean injection combustor system includes a combustor liner defining a combustor chamber. Also included is a sleeve surrounding at least a portion of the combustor liner, the combustor liner and the sleeve defining a cooling annulus for routing a cooling airflow from proximate an aft end of the combustor liner toward a forward end of the combustor liner. Further included is a cooling airflow divider region configured to split the cooling airflow into a first cooling airflow portion and a second cooling airflow portion, wherein the first cooling airflow portion is directed to at least one primary air-fuel injector, wherein the second cooling airflow portion is directed to at least one lean-direct injector extending through the sleeve and the cooling annulus for injection of the second cooling airflow portion into the combustor chamber.

Abstract: A system includes a turbomachine including a first chamber configured to contain a first fluid and a second chamber configured to contain a second fluid. The turbomachine also includes a barrier disposed between the first and second chambers. The barrier is configured to separate the first fluid and the second fluid. Additionally, the barrier includes a first surface facing the first chamber and a second surface facing the second chamber. The turbomachine also includes an orifice extending from the first chamber to the second chamber. The orifice defines a fluid passageway. Additionally, the turbomachine includes a tube including a first end and a second end. The first end is coupled to the first surface and is disposed about a perimeter of the orifice. The tube is configured to at least partially contain the second fluid.
