20090077795 | Replaceable Staking Insert - A rotating assembly. The rotating assembly may include a wheel, a slot positioned about the wheel with the slot having a staking recess positioned therein, a wheel attachment positioned within the slot, and a staking insert positioned within the staking recess. The staking recess axially retains the staking insert and the wheel attachment radially retains the staking insert. | 03-26-2009 |
20090077802 | METHOD FOR MAKING A COMPOSITE AIRFOIL - A method of manufacturing a composite airfoil includes the step of providing a core made of a metal or ceramic material. A plastic airfoil portion is molded to envelope at least a portion of the core. | 03-26-2009 |
20090081032 | COMPOSITE AIRFOIL - A turbine component includes mounting structure for attaching the turbine component. A core is attached to the mounting structure. The core is made from a structural material. A plastic airfoil portion envelopes at least a portion of the core. | 03-26-2009 |
20090252611 | Axial compressor blade retention - An axial retention system for restraining axial movement of a machine component having a dovetail within a complimentary-shaped dovetail slot includes: a first substantially T-shaped groove formed in a bottom surface of the dovetail slot; a second substantially T-shaped groove formed in a bottom surface of the dovetail, the first and second grooves in alignment when the dovetail is located within the dovetail slot to thereby form a closed periphery substantially T-shaped slot having a stem portion and a lateral cross portion at one end of the stem component, wherein the other end of the stem is open; and a compressible locking clip adapted for insertion within the substantially T-shaped slot, the locking clip having a pair of oppositely extending lugs receivable in opposite ends of the lateral cross portion. | 10-08-2009 |
20100061862 | AIRFOIL SHAPE FOR A COMPRESSOR BLADE - An article of manufacture having a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in TABLE A. X and Y are distances in inches which, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z in inches. The profile sections at the Z distances can be joined smoothly with one another to form a complete airfoil shape. | 03-11-2010 |
20100215490 | Systems, Methods, and Apparatus for Linking Machine Stators - Systems, methods, and apparatus for linking machine stators are provided. A bracket may be utilized to link adjacent stators within a machine, for example, a turbine. The bracket may include a body portion, a first plurality of extensions, and a second plurality of extensions. The body portion may include a first edge operable to align with a base of a first stator and a second edge opposite the first edge and operable to align with a base of a second stator. The first plurality of extensions may extend from the first edge and may be operable to align with at least one corresponding groove on the base of the first stator. The second plurality of extensions may extend from the second edge and may be operable to align with at least one corresponding groove on the base of the second stator. When utilized to link the first stator and the second stator, the bracket may facilitate a reduction of vibrations in the first stator and the second stator. | 08-26-2010 |
20100284814 | Machine component retention - An axial retention system for restraining axial movement of a first machine component having a dovetail within a complimentary-shaped dovetail slot in a second machine component that includes a first curved groove formed in a bottom surface of the dovetail slot and a second curved groove formed in a bottom surface of the dovetail. The first and second grooves are in alignment when the dovetail is located within the dovetail slot to thereby form a closed periphery aperture. A curved locking clip is received within the closed periphery aperture. An optional cover plate may be placed over the ends of the locking clip, with ends of the locking clip deformed by, for example, swaging. | 11-11-2010 |
