涡轮机叶片和隔板构造
摘要：
轴流涡轮机叶片和隔板构造包括静涡轮机叶片(20)的环和具有缝隙(41、43)的内间隔环和外间隔环(40、42)，缝隙(41、43)成形为容纳叶片的内平台部分和外平台部分(22、23)，以此平台部分和间隔环一起形成了涡轮机隔板的内通道壁和外通道壁。叶片特别的特征是内平台部分和外平台部分(22、23)具有直侧缘(22B、22C)和(23B、23C)，它们通过弯曲的前缘(22D和23D)相互结合，前缘(22D和23D)在平面视图中具有如下的形状，在翼片(21)的前缘(26)的区域内该形状跟随角部圆角(24)的边缘。
摘要（英）：

An axial flow turbine blade and diaphragm construction comprises an annulus of static turbine blades 20 and inner and outer spacer rings 40, 42 having apertures 41, 43 shaped to accommodate inner and outer platform portions 22, 23 of the blades, whereby the platform portions and the spacer rings together form inner and outer port walls of the turbine diaphragm. A particular feature of the blades is that the inner and outer platform portions 22 and 23 have straight side edges 22 B, 22 C and 23 B, 23 C, which are joined to each other by curved leading edges 22 D and 23 D that in plan view have a shape that follows the edge of the corner fillet 24 in the region of the leading edge 26 of the aerofoil 21.
