| 20090031802 | ROTOR ALIGNMENT SYSTEM AND METHOD - Disclosed herein is a rotor to stator alignment method. The alignment method includes, positioning a plurality of eccentric rings between the rotor and a stator, and rotating at least one of the plurality of eccentric rings relative to the stator thereby reducing eccentricity of the rotor with the stator. | 02-05-2009 |
| 20090053042 | METHOD AND APPARATUS FOR CLEARANCE CONTROL OF TURBINE BLADE TIP - A gas turbine including a casing and a shroud ring, the gas turbine including an attachment device rigidly attached to the casing and at least one of the shroud ring and a duct attached to the shroud ring, wherein the device allows the shroud ring to expand and contract independent of the casing and provides limited net axial growth of the shroud ring. | 02-26-2009 |
| 20090053046 | METHOD, SYSTEM AND APPARATUS FOR TURBINE DIFFUSER SEALING - A turbine diffuser is disclosed. The turbine diffuser includes a diffuser segment having a forward end and an aft end with a flange disposed at the aft end of the diffuser segment. The diffuser segment is joinable to an adjacent diffuser segment via the flange, which includes a seal retainer that is securedly connectable in a radial direction with a seal. | 02-26-2009 |
| 20090097968 | APPARATUS AND METHOD FOR CLEARANCE CONTROL OF TURBINE BLADE TIP - An inner shell for a rotating machine including at least one segment; and at least one complementary segment in operable communication with the at least one segment, the segments forming a support structure for a shroud ring; wherein the at least one segment and the at least one complementary segment are individually moved to change a set of dimensions defined by the at least one segment and the at least one complementary segment. A method for controlling a dimension of the shroud ring in a rotating machine is also disclosed. | 04-16-2009 |
| 20100189551 | Systems and Methods of Reducing Heat Loss from a Gas Turbine During Shutdown - A method operates a gas turbine that includes a compressor section, a turbine section and an extraction cooling system. The method includes monitoring an operation of the gas turbine, directing a cooling air flow through the extraction cooling system from the compressor section to the turbine section in response to normal operation of the gas turbine, and directing a warming air flow through the extraction cooling system to the compressor section and the turbine section in response to shutdown of the gas turbine. | 07-29-2010 |
| 20100272558 | Turbine rotor support apparatus and system - An apparatus to support a rotor of a turbine engine disposed upon a support surface is disclosed. The apparatus includes a housing, a rotor support bearing disposed within the housing, and a support leg in operable communication with the housing and in direct structural connection with the support surface. | 10-28-2010 |
| 20100296936 | LOW STRESS CIRCUMFERENTIAL DOVETAIL ATTACHMENT FOR ROTOR BLADES - A retaining system is provided for circumferential entry rotor dovetails inserted into dovetail slot in a rotor. A plurality of rotor blade dovetails are circumferentially slidable into and along the dovetail slot, with each rotor blade dovetail having a neck and a pair of oppositely oriented lobes. A plurality of rail segments are circumferentially slid into channels in the dovetail slot between the dovetail lobes and the respective disk hoops. The rail segments define a first pressure face that engages against an outward pressure face of the dovetail lobes, and a second pressure face that engages against an inward pressure face of the respective disk hoop component. | 11-25-2010 |
| 20100303606 | TURBOMACHINE COMPRESSOR WHEEL MEMBER - A turbomachine includes a rotor assembly including a wheel member. The wheel member includes a first portion that extends to a second portion through an intermediate portion. The intermediate portion partially defines a first wheel space and a second wheel space. The wheel member further includes a rotor inertia belt member arranged at the second portion. The rotor inertia belt member includes an extraction air cavity. The extraction air cavity includes an inlet, a first plurality of extraction air passages each including an inlet section and an outlet section, the outlet section leading into the first wheel space, and a second plurality of extraction air passages each including an inlet portion and an outlet portion, the outlet portion leading into the second wheel space. | 12-02-2010 |
| 20110000222 | GAS TURBINE ROTOR-STATOR SUPPORT SYSTEM - A system to support a rotor and a stator of a rotating machine disposed upon a support base, the system including at least one support leg in operable communication with a bearing of the rotor and with the support base; and at least one strut in operable communication with the at least one support leg and with the stator. | 01-06-2011 |
