涡轮叶片的冷却构造
摘要：
在用于从内部冷却涡轮叶片(1)的结构中，在所述涡轮叶片(1)内设置冷却介质通路(5)，使该冷却介质通路(5)具有相互平行延伸的多个大致圆筒状的空间(S1、S2)的一部分相互重合的形状，将向所述冷却介质通路供给冷却介质(CL)的冷却介质供给通路(9)，在相对于所述冷却介质通路的长度方向成为锐角的方向上，与包含所述冷却介质通路的周壁(15)的部分相连接。
摘要（英）：

In a structure for internally cooling a turbine blade, a cooling medium passage is provided in the turbine blade. The cooling medium passage has a shape in which a plurality of cylindrical spaces, each having substantially cylindrical shape, extending in parallel with each other partially overlap each other. A cooling medium supply passage that supplies a cooling medium to the cooling medium passage is connected to a portion of the cooling medium passage that includes a peripheral wall, in a direction that forms an acute angle with respect to a longitudinal direction of the cooling medium passage.
