摘要: Composite components having structurally reinforced contact interfaces are provided. In one example, the component can include an inner laminate formed of one or more inner plies having reinforcement fibers oriented along a reference direction within a matrix material. The component can also include an interface laminated positioned on the inner laminate along at least a portion of a contact surface of the component. The interface laminate is formed of one or more interface plies having reinforcement fibers oriented along a direction offset from the reference direction within a matrix material. Methods for fabricating such components are also provided.

摘要: The invention relates to a work station for electrochemically machining a workpiece, having a number of recesses, including a base structure; a module which is fastened to the base structure and is configured to electrochemically machine the workpiece. A workpiece holder is fastened to the base structure. The workpiece holder is movable relative to the base structure along a feed axis which is parallel to the axis of rotation of the module. The module includes an electrode carrier arrangement, which is coupled to the module base body so the electrode carrier arrangement can be rotated together with the module base body about the axis of rotation of the module. The electrode carrier arrangement has a carrier frame and an electrode frame, where at least one electrode is detachably fastened to the electrode frame.

摘要: A highly efficient gas turbine engine is provided. The fan of the gas turbine engine is driven from a turbine via a gearbox, such that the fan has a lower rotational speed than the driving turbine, thereby providing efficiency gains. The efficient fan system is mated to a core that has low cooling flow requirements and/or high temperature capability, and which may have particularly low mass for a given power.

摘要: A method is provided having the following steps: a) providing a drive-out device which has a drive-out punch that is actuated via a hydraulic cylinder; b) positioning the drive-out device between two adjacent wheel discs of the rotor such that a longitudinal axis of the drive-out punch is flush with the receiving groove of the blade to be driven out; c) adjusting a maximum pressure which can be applied to the hydraulic cylinder; d) extending the drive-out punch such that the drive-out punch presses against the blade root of the blade to be driven out with increasing pressure; e) reducing the pressure as soon as the pressure has reached the maximum pressure; and f) cyclically repeating the steps d) and e) until the blade has been removed from the receiving groove. A drive-out device is further provided.

摘要: Rotor assemblies and methods for manufacturing airfoils for rotor assemblies are provided. For example, a rotor assembly comprises a rotary structure extending circumferentially about an axial centerline of a gas turbine engine and an airfoil having a root and a tip. The root is coupled to the rotary structure and has a bulbous shape. The airfoil is formed from a plurality of composite plies, a portion of which defines at the root first and second end surfaces, which are in contact with the rotary structure and together define a chisel-shaped end of the root. In another embodiment, a rotor assembly comprises an outer rotor extending circumferentially about an axial centerline of a gas turbine engine and a composite outer rotor blade having a root and a tip. The blade root is coupled to the outer rotor and extends inward along a radial direction toward the axial centerline.

摘要: A structure and a method of constructing a root joint and blade retention mechanism of a composite airfoil of a propulsor blade is presented. The retention assembly includes an inner sleeve configured to retain a root area of the composite propulsor blade. The inner sleeve is fixedly attached to an inner surface of the root area by a resin transfer molding process. An outer sleeve is bonded to an outer surface of the composite propulsor blade after the completion of the resin transfer molding process. At least one bearing assembly is disposed within an annular groove of the outer sleeve. The bearing assembly rotatably couples the propulsor blade and the retention assembly to a hub assembly.
