| 20090208321 | TURBINE BLADE TIP CLEARANCE SYSTEM - A system for adjusting a clearance between blade tips of a turbine and a shroud assembly encircling the turbine in a turbine engine is disclosed herein. The system includes a first fluid passageway operable to extend from a first source of fluid at a variable pressure to a shroud assembly of a turbine engine. The first fluid passageway directs a first stream of fluid to the shroud assembly. The system also includes a first valve positioned along the first fluid passageway and moveable between open and closed configurations. The first valve is biased to the open configuration and moved to the closed configuration passively and directly by a first predetermined level of pressure of the first stream of fluid. During periods of relatively low power production of the turbine engine, the first valve is in the open configuration and moves to the closed configuration when power production of the turbine engine increases from relatively low power production. | 08-20-2009 |

| 20100119354 | TURBOMACHINE WITH FAILURE PROTECTION - A turbomachine has a housing, a rotor shaft extending along and rotatable about an axis in the housing, and a pair of axially spaced axial-thrust bearings in the housing carrying the shaft and normally only permitting a predetermined small axial displacement of the shaft in the housing. An impeller is rotationally fixed on the shaft. An axially fixed transmission gear is rotationally coupled to the shaft and has an axially directed gear face. A collar fixed axially on the shaft has an axially directed collar face confronting the gear face and normally spaced from the gear face by a clearance equal to more than the predetermined axial displacement. Thus on failure of one of the bearings and axial overtravel of the shaft the gear face and collar face engage each other and limit axial movement of the shaft. | 05-13-2010 |
| 20110129331 | SYSTEM FOR CONTROLLING THE THRUST AFFECTING A SHAFT - An embodiment of the present invention provides a system for controlling the overall thrust extorted on a rotor. The system includes a chamber that encloses a portion of the rotor. A seal system may seal the chamber and the rotor. A fluid system may provide a pressurized fluid to the chamber and the fluid may oppose the thrust exerted by the rotor. The system may also include a control system configured for monitoring the position of the rotor; and utilizing the pressurized fluid to reduce the overall thrust load. | 06-02-2011 |

| 20130017062 | TURBO MACHINE WITH MAGNETIC BEARINGSAANM KOCHETOV; DmitryAACI MoscowAACO RUAAGP KOCHETOV; Dmitry Moscow RUAANM WIEBE; FrankAACI Dormagen-GohrAACO DEAAGP WIEBE; Frank Dormagen-Gohr DE - A turbomachine has a housing, a rotor shaft centered on an axis, and a plurality of bearings supporting the shaft in the housing for rotation about the axis. At least one of the bearings is an active magnetic bearing. An impeller is fixed on the rotor shaft. A copper layer is fixed to a surface of the rotor shaft and rotatable therewith. A sensor fixed in the housing adjacent the shaft surface can detect the copper layer and generate an output corresponding to a position of the layer from the sensor fixed in the housing. A controller connected between the sensor means and the active magnetic bearing shifts the rotor in the housing in accordance with the output. | 01-17-2013 |
