  • Patent number: 7258530
    Abstract: An airfoil (44) formed of a plurality of pre-fired structural CMC panels (46, 48, 50, 52). Each panel is formed to have an open shape having opposed ends (54) that are free to move during the drying, curing and/or firing of the CMC material in order to minimize interlaminar stresses caused by anisotropic sintering shrinkage. The panels are at least partially pre-shrunk prior to being joined together to form the desired structure, such as an airfoil (42) for a gas turbine engine. The panels may be joined together using a backing member (30), using flanged ends (54) and a clamp (56), and/or with a bond material (36), for example.

  • Patent number: 7255535
    Abstract: Embodiments of the invention relate to various cooling systems for a turbine vane made of stacked ceramic matrix composite (CMC) laminates. Each airfoil-shaped laminate has an in-plane direction and a through thickness direction substantially normal to the in-plane direction. The laminates have anisotropic strength characteristics in which the in-plane tensile strength is substantially greater than the through thickness tensile strength. Such a vane construction lends itself to the inclusion of various cooling features in individual laminates using conventional manufacturing and forming techniques. When assembled in a radial stack, the cooling features in the individual laminates can cooperate to form intricate three dimensional cooling systems in the vane.

  • Patent number: 7247003
    Abstract: A stacked ceramic matrix composite lamellate assembly (10) including shear force bearing structures (48) for resisting relative sliding movement between adjacent lamellae. The shear force bearing structures may take the form of a cross-lamellar stitch (50), a shear pin (62), a warp (90) in the lamellae, a tongue (104) and groove (98) structure, or an inter-lamellar sealing member (112), in various embodiments. Each shear force bearing structure secures a subset of the lamellae, with at least one lamella being common between adjacent subsets in order to secure the entire assembly.

  • Patent number: 7225109
    Abstract: A method and apparatus for detecting mechanical problems in machinery used in a process. A model of the process is developed using a modeling technique such as advanced pattern recognition and the model is used to generate predicted values for a predetermined number of the operating parameters of the process and vibration parameters of the machinery. Statistical process control methods are used to determine if the difference between the predicted and actual measured values for one or more of the parameters exceeds a configured statistical limit. A rule set is used to indicate an actual or probable fault in the machinery.

  • Patent number: 7198860
    Abstract: Ceramic tile (32) insulation for protecting a substrate material (34) in a high temperature environment. A plurality of ceramic tiles (78) may be used in combination with a monolithic layer of ceramic insulation (80) to protect a fillet region (76) and an airfoil section (80), respectively, of a gas turbine vane (72). Individual ceramic tiles (84) may be applied to repair a damaged area of the monolithic insulating layer. Ceramic tile insulation may be applied in two layers (56, 58) with the material properties of the two layers being different, and with the gaps (38) of the two layers being misaligned.

  • Patent number: 7188685
    Abstract: A bottom hole assembly is rotatably adapted for drilling directional boreholes into an earthen formation. It has an upper stabilizer mounted to a collar, and a rotary steerable system. The rotary steerable system has an upper section connected to the collar, a steering section, and a drill bit arranged for drilling the borehole attached to the steering section. The steering section is joined at a swivel with the upper section. The steering section is actively tilted about the swivel. A lower stabilizer is mounted upon the steering section such that the swivel is intermediate the drill bit and the lower stabilizer.

  • Patent number: 7190135
    Abstract: A method for implementing control signal linearization for an electric motor is disclosed. In an exemplary embodiment, the method includes receiving a desired voltage command to be applied to the motor and determining whether the magnitude of the desired voltage command falls between a first value and a second value. If the magnitude of the desired voltage command falls between the first value and the second value, then modulating a voltage command between the first and the second value over a determined sample period, thereby resulting in the application of a modulated voltage command to the motor.

  • Patent number: 7182250
    Abstract: A computing device with an embedded microprocessor or micro-controller, including a software stack which comprises a content manager, and a runtime environment positioned in the stack above or together with a hardware abstraction layer. The content manager is not specific to any one design of runtime environment or hardware abstraction layer, so that several different designs of runtime environment and/or hardware abstraction layer can each operate with the same content manager. This de-couples the content manager from the runtime environment and/or hardware abstraction layer (e.g. a Java Virtual machine; elements of the operating system). The core advantage is that a single content manager can be used across multiple runtime environments and/or hardware abstraction layers; runtime environments and OSs can therefore be swapped without needing to re-write the content manager.

  • Patent number: 7153096
    Abstract: Embodiments of the invention relate to a robust turbine vane made of stacked airfoil-shaped CMC laminates. Each laminate has an in-plane direction and a through thickness direction substantially normal to the in-plane direction. The laminates have anisotropic strength characteristics in which the in-plane tensile strength is substantially greater than the through thickness tensile strength. Thus, the laminates can provide strength in the direction of high thermal gradients and, thus, withstand the associated high thermal stresses. The laminates are relatively weak in through thickness (interlaminar) tension, but, in operation, relatively low through thickness tensile stresses can be expected. The laminates can be strong in through thickness compression; accordingly, the laminate stack can be held in through thickness compression by one or more fasteners.

  • Publication number: 20060270521
    Abstract: According to a preferred embodiment of the present invention, a clutch is applied when the vehicle comes to a stop. The application of this clutch locks the output shaft with energy stored therein. When the shift selector is then moved to the park position, the clutch releases the stored energy in a controlled manner by slipping the clutch plates. The controlled slipping reduces the noise as the park pawl tooth contracts an output gear tooth.
