    • A retention mechanism for an electronic assembly which has a substrate and a heat sink. The retention mechanism includes a substrate slot that receives the substrate and a heat sink slot that receives the heat sink. There may be two retention mechanisms that are attached to a printed circuit board adjacent to an electrical connector. There may be two heat sink slots symmetrically located about the substrate slot so that the mechanism can be mounted to a left side or a right side of the connector. The symmetric slots eliminate the need for a left side mechanism and a right side mechanism. The retainer mechanism may also have a nut retainer that captures a nut that is used to attach the mechanism to the printed circuit board. The nut retainer allows the nut to be transported with the retainer mechanism during an assembly process.
    • 一种用于具有基板和散热器的电子组件的保持机构。 保持机构包括接收基板的基板槽和接收散热器的散热槽。 可能有两个固定机构连接到与电连接器相邻的印刷电路板。 可能有两个对准地位于基板槽周围的散热槽,使得该机构可以安装在连接器的左侧或右侧。 对称槽消除了对左侧机构和右侧机构的需要。 保持器机构还可以具有螺母保持器,其捕获用于将机构附接到印刷电路板的螺母。 螺母固定器允许螺母在组装过程中与保持器机构一起运输。

    • A turbine blade locking device axially retains a turbine blade (1) inserted in an axial, profiled slot (10) of a turbine disk (6). The turbine disk (6) is provided with a locking groove (8) passing through the slot (10) and extending radially in the plane of the turbine disk (6). A locking pin (4) is inserted in the locking groove (8) and the blade root (3) is provided at its bottom side with a notch (9) aligning with the locking groove (8). A portion of an elastic element (5) is arranged radially below the locking pin (4) to pre-load the locking pin (4) in a radially outward direction and into the notch (9).

    • A hollow turbine blade cooled with compressor air is divided into a cooling air chamber (6) and into impingement air cooling chambers (8, 9) by inner, supporting partitions (3, 4). The cooling air is conveyed from the cooling air chamber into the impingement air cooling chamber via impingement air channels (7) provided in the partitions. The impingement air channels are concave with regard to the adjacent outer wall (2) of the blade airfoil (1) and arranged completely in the hot area near the outer wall and, in addition, have an oblong or elliptical cross-section whose longitudinal axis agrees with the radial orientation of the turbine blade. By reduced stress concentration in the area of the impingement air channels, the fatigue and creep characteristics are improved and life is increased.
    • 用压缩机空气冷却的空心涡轮叶片由内部的支撑隔板(3,4)分为冷却空气室(6)和冲击空气冷却室(8,9)。 冷却空气通过设置在隔板中的冲击空气通道(7)从冷却空气室输送到冲击空气冷却室。 冲击空气通道相对于叶片翼型件(1)的相邻外壁(2)是凹形的,并且完全布置在靠近外壁的热区域中,并且还具有长方形或椭圆形的横截面,其纵向轴线 与涡轮叶片的径向取向一致。 通过减少冲击空气通道的应力集中,提高疲劳和蠕变特性,延长使用寿命。
