    • A system and method for modeling cross system content between a hub and one or more backend systems is disclosed. Model content of one or more data models is stored in a model stack defined in a storage. The model content of each of the one or more data models includes model metadata representing a model of a corresponding backend system. Cross model content is stored in a cross model stack defined in the storage. The cross model content includes reference metadata representing one or more references associated with a data model of one backend system and that reference a data model of another backend system. Central cross model content is stored in a central cross model stack in the storage. The central cross model content includes one or more cross elements that do not belong to the model content of any of the one or more data models, and that establish a connection between two data models of different backend systems.
    • 公开了一种用于在集线器和一个或多个后端系统之间建模跨系统内容的系统和方法。 一个或多个数据模型的模型内容存储在存储器中定义的模型栈中。 一个或多个数据模型中的每一个的模型内容包括表示对应后端系统的模型的模型元数据。 交叉模型内容存储在存储器中定义的交叉模型堆栈中。 交叉模型内容包括表示与一个后端系统的数据模型相关联并且引用另一个后端系统的数据模型的一个或多个引用的参考元数据。 中央交叉模型内容存储在存储器中的中央交叉模型堆栈中。 中央交叉模型内容包括不属于一个或多个数据模型中的任一个的模型内容的一个或多个交叉元素,并且建立不同后端系统的两个数据模型之间的连接。

    • A rotor blade for fastening on the rotor of a turbomachine, especially of a compressor of a gas turbine, has a blade airfoil and a blade root (15) which adjoins the lower end of the blade airfoil and extends along a blade axis and by which the rotor blade, in an encompassing slot which is arranged on the outer periphery of the rotor, is retained between two spacers (12, 18) which follow each other in the circumferential direction and which in their turn are retained in the slot. The blade root (15) is formed with a T-shape in cross section and includes circumferential shoulders (16, 16′) which fit under the adjacent spacers (12, 18), and the spacers (12, 18), in the direction of the blade axis, engage by retaining surfaces (20) in undercuts (24) in the slot. Reduced production cost with comparable service life is achieved by the T-shaped blade root (15) being milled, and, for reducing the mechanical stresses at the transitions of the blade root (15) to the shoulders (16, 16′), by a relief groove (21), which extends in the direction of the blade axis.
    • 用于紧固在涡轮机的转子上的转子叶片,特别是用于燃气轮机的压缩机的转子具有叶片翼型件和叶片根部(15),该叶片翼型件和叶片根部(15)邻接叶片翼型件的下端并且沿叶片轴线延伸 设置在转子的外周上的包围槽中的转子叶片被保持在两个在圆周方向上彼此相邻并且其又保持在槽中的间隔件(12,18)之间。 叶片根部(15)的横截面形成为T形,并且包括在相邻的间隔件(12,18)下面配合的周向肩部(16,16')和间隔件(12,18)的方向 的刀片轴线通过保持表面(20)接合在槽中的底切(24)中。 通过被铣削的T形叶片根部(15)实现降低生产成本并且具有相当的使用寿命,并且为了将刀片根部(15)向肩部(16,16')的转变处的机械应力减小,通过 沿刀片轴线方向延伸的释放槽(21)。
