Abstract:
A replacement light bulb assembly for use in an incandescent light fixture utilizes a light emitting diode (LED). An LED is bonded to a base that fits within a typical incandescent light bulb fixture. The LED is electrically connected to the base and a center post within the base to form an electrical circuit when assembled within an incandescent light fixture. A control is connected to the LED to modify the LED output. The control can also be used to modify the voltage or current requirements of the light bulb assembly for use with DC current or AC current applications. An external shield or lens, or an internal shield or lens, may be added to the light bulb assembly or directly to the LED to alter the light emitted. Several variations of the light bulb assembly having each having base corresponding to a typical incandescent light bulb fixture may be available.
Abstract:
A method of making a platform of a blade includes the steps of creating two platform sections by solidifying a material with a fabric in a mold and positioning a band of fabric around the two platform sections to retain an airfoil and define a blade. The method further includes the step of bonding the two platform sections together by solidifying the material to define a platform of a solid material. The platform is not bonded to the airfoil.
Abstract:
One exemplary embodiment according to this disclosure relates to a system includes a blade outer air seal (BOAS), and a meter plate. A portion of the meter plate is provided radially outward of a radially outermost surface of the BOAS.
Abstract:
A disclosed resin transfer molding tool includes a mold defining an internal cavity of a fixed geometry and a bladder configured to be received within the internal cavity and define a flexible interface surface for surrounding a molded article. The bladder is fillable with a fluid material to exert a pressure on a surface of the molded article within the mold.
Abstract:
An airfoil includes a core having a first surface, a skin having a second surface disposed over at least a portion of the first surface of the core, and at least one of a transient liquid phase (TLP) bond and a partial transient liquid phase (PTLP) bond. The bond(s) are disposed between the first surface and the second surface, joining the skin to the core.
Abstract:
A gas turbine engine component assembly includes a ceramic component having a first thermal characteristic. A metallic component has a second thermal characteristic. A bonding material secures the ceramic component to the metallic component. The bonding material includes at least one of a transient liquid phase bond and a partial transient liquid phase bond. The bonding material is configured to withstand a shear stress parameter relating to a differential between the first and second thermal characteristics.
Abstract:
An assembly for a turbine engine includes a plurality of vane segments. The vane segments are fastened together and form an adjustable stator vane that pivots about a variable vane axis. The adjustable stator vane includes a stator vane body, a shaft and a flange. The stator vane body extends axially between a first end and a second end, and includes an airfoil, a body surface and a cavity. The body surface is located at the first end. The cavity extends axially from an inlet in the body surface and into the airfoil. The shaft extends along the variable vane axis from the first end. The flange extends circumferentially at least partially around the inlet, and radially from the stator vane body. A first of the vane segments includes the flange. A second of the vane segments includes at least a portion of the airfoil.
