透平涡形管道和动翼的构造
摘要：
在本发明中对透平涡形管道和透平动翼进行了改进。在径流式透平的涡形管道的构造中，半径方向的宽度(ΔR)与旋转轴心方向的宽度(B)的涡形管道宽度比ΔR/B构成为ΔR/B＝0.3～0.7。另外，动翼在上述作动气体流入的入口端面的覆环侧及轮毂侧具有将角度切落一定量的切落部。
摘要（英）：

The improvements are made in the turbine scroll and the turbine blades. The scroll structure for the radial turbines is characterized by the foregoing scroll having a scroll width ratio between the width in the radial direction (DELTA R) and the width in the direction of the rotation (B) ranging from DELTA R/B = 0.3 to 0.7. It is further characterized by the configuration in which the turbine blades have cut-away areas at the blade corners by a prescribed amount, which are provided on the inlet edge at the shroud side and hub side where the operating gas flows.
