TURBINE ROTOR

A turbine rotor of a turbine includes a hub that serves as an axis of rotation, and a plurality of turbine blades that are arranged on a peripheral surface of the hub and receive and direct working fluid flowing into from an inlet toward an outlet. The turbine blades each have a line extending along...

Beschreibung
Zusammenfassung:	A turbine rotor of a turbine includes a hub that serves as an axis of rotation, and a plurality of turbine blades that are arranged on a peripheral surface of the hub and receive and direct working fluid flowing into from an inlet toward an outlet. The turbine blades each have a line extending along a shroud-side edge of the turbine blade from the inlet to the outlet as a shroud line. The shroud line includes an entrance-side shroud line La that makes a small change from the inlet toward the outlet in a blade angle with respect to the axis of rotation, a center shroud line Lb that extends from the outlet side of the entrance-side shroud line La and makes a greater change than that of the entrance-side shroud line La, and an exit-side shroud line Lc that extends from the outlet side of the center shroud line Lb to the outlet and makes a smaller change than that of the center shroud line Lb.
