Rotor blade of turbomachine (Chinesisch)

A moving blade of a turbo machine, comprising: a blade leaf; a blade root configured to mount the moving blade to a hub body and fir tree-like shaped with at least two projections spaced apart from one another seen in a radial direction; an inner shroud radially arranged between the blade leaf and the blade root seen in a radial direction; a cooling passage integrated in the blade leaf and the blade root for a cooling medium, wherein an inlet of the cooling passage is formed on a radially inner side of the blade root and is formed by a first inlet passage portion and a second inlet passage portion arranged behind the first inlet passage portion seen in an axial direction of the blade root. A material web extends between the first inlet passage portion and the second inlet passage portion.The first inlet passage portion and the second inlet passage portion merge into a unifying passage portion arranged radially outside the uppermost projection of the blade root and radially inside of the inner shroud seen in a radial direction.

一种涡轮机的动叶片具有：叶片叶；叶片根部，用于将动叶片安装到轮毂体上，其中，叶片根部形成为杉树状，在径向方向上看具有至少两个彼此间隔开的突起；内罩，在径向方向上看布置在叶片叶和叶片根部之间；冷却通道，其集成在叶片叶和叶片根部中以用于冷却介质，其中，冷却通道的入口在叶片根部上在径向内侧形成。冷却通道的入口由第一入口通道部分和第二入口通道部分形成，在叶片根部的轴向方向上看，第二入口通道部分布置在第一入口通道部分后面，材料腹板在第一入口通道部分和第二入口通道部分之间延伸。第一和第二入口通道部分合并成合并通道部分，在径向方向上看，该合并通道部分被布置在叶片根部的最上面突起的径向外侧并在内罩的径向内侧。
