    摘要: A workpiece clamp device with single side is disclosed. When a bolt is screwed in relative to a base plane, an elastic member is compressed by a first and a second stop portions and a second clamp surface of a driving block is limited by a second wall surface. A first inclined surface is pushed leftward by a second inclined surface so that a tool is clamped by the first clamp surface and a first wall surface. When the bolt is screwed out relative to the base plane, the elastic member is reset due to the compression of the first and the second stop portions. Since the second clamp surface is limited by a second wall surface, the first inclined surface is pushed rightward by the second inclined surface to move the driving block upward so that the force for clamping the tool is released and the tool is disassembled.

    摘要: A gas turbine engine compressor blade includes an airfoil and a root section connected to a blade platform therebetween and an at least partially curved cropped corner of the blade platform. The corner shape and size may avoid resonance of blade during engine operation. Corner may be J-shaped including a straight section extending from pressure side edge towards suction side edge of platform and curved section extending from straight section to uncropped portion of platform trailing edge of the platform. A method of designing the cropped corner includes choosing shapes sizes of the cropped corner for numerically analyzing and determining shape and size for cropped corner using numerical model to iteratively numerically analyze aerodynamically cropped platform with different shapes and sizes of cropped corner. Numerical model may be validated with engine or component testing of blade having a cropped platform with at least one of the shapes and sizes.

    摘要: A method for balancing a compressor rotor assembly including a forward weldment (211) and an aft weldment (212) includes pre-balancing the aft weldment (212) of the compressor rotor assembly (210) with compressor disks (220) prior to populating the compressor disks (220) with circumferentially installed compressor rotor blades (230). Pre-balancing the aft weldment (212) includes measuring a rotational balance of the aft weldment (212). Pre-balancing the aft weldment (212) also includes determining a number of underplatform weights (260) needed and a location for each underplatform weight (260) within a circumferential slot (236) of one the compressor disks (220). Pre-balancing the aft weldment (212) further includes mounting each underplatform weight (260) in the determined location.

    摘要: A turbomachine aerofoil blade has an aerofoil body portion and a dovetail root fixing at the base of the aerofoil body portion which slides, in use, into a correspondingly shaped slot of a rotor of the turbomachine. The dovetail root fixing has a neck portion, and support flanks engage with matching angled surfaces of the slot under centrifugal loading of the aerofoil blade to support the aerofoil blade on the rotor. The neck portion is shaped such that a rotational adjustment of the aerofoil blade relative to its angular position when supported under centrifugal loading is needed to provide adequate clearance at the neck portion to allow the dovetail root fixing to slide into the slot. On centrifugal loading the engagement of the support flanks with the matching angled surfaces of the slot forces a reversal of the rotational adjustment and reduces the clearance at the neck portion.
