    • The blade for a gas turbine includes a blade airfoil having a leading edge and a trailing edge and extending in the blade longitudinal direction up to a blade tip, and at the blade tip the blade airfoil merges into a shroud segment, wherein on the shroud segment a first rib, projecting upwards, is arranged in the flow direction, extending transversely to the flow direction, and upstream of the first rib, in the region of the leading edge of the blade airfoil, a winglet is formed on the shroud segment for guiding of the hot gas flow in this region. With such a blade, a longer service life is achieved by provision being made for direct cooling of the winglet.
    • 用于燃气涡轮的叶片包括具有前缘和后缘并且在叶片纵向方向上延伸直到叶片尖端的叶片翼型件,并且在叶片尖端处,叶片翼型件合并成护罩段,其中在护罩段 向上突出的第一肋沿流动方向布置,横向于流动方向延伸,并且在第一肋的上游处在叶片翼型的前缘的区域中,在护罩段上形成小翼以用于引导 的热气流在这个地区。 利用这种叶片,通过提供用于小翼的直接冷却来实现更长的使用寿命。

    • The aim of the invention is to provide a simple, safe to handle fixing device for a par that can be inserted between adjacent supports, especially centrally. Locating holes that are aligned approximately flush with each other, for holding elements of the part are provided in the adjacent supports. The holding elements are configured in the form of pegs mounted in the part. The pegs are provided with a screw thread at their second ends and each engage in a corresponding screw of sliding pieces that can slide in the part. The sliding pieces can be slid and stopped in a plane defined by the longitudinal axes of the pegs. The part has at least one pair of pegs on opposite outer surfaces that are flush with each other through the part.
    • 本发明的目的是提供一种简单,安全的手柄固定装置,其可以插入在相邻的支架之间,特别是中央。 在相邻的支撑件中设置有用于保持部件的元件的彼此大致齐平的定位孔。 保持元件以安装在该部件中的钉的形式构造。 钉在其第二端设置有螺纹,并且各自接合可在部件中滑动的滑动件的相应螺钉。 滑动件可以在由钉的纵向轴线限定的平面内滑动和停止。 该部件在相对的外表面上具有至少一对彼此通过该部件彼此齐平的栓钉。
