Document Type and Number:
WIPO Patent Application WO/2016/151849
Kind Code:
A1
Abstract:
A turbine rotor blade according to an embodiment of the present invention comprises: a hub part that is connected to one end of a rotating shaft; a plurality of main blades that are provided on a peripheral surface of the hub part so as to be spaced apart from one another; and a short blade that is provided between two adjacent main blades among the plurality of main blades. Between two adjacent main blades, an inter-blade flow channel is formed along which a fluid flows from the outside toward the inside in a radial direction of the turbine rotor blade. A hub-side end of a leading edge of the short blade is positioned closer to the inside in the radial direction than hub-side ends of leading edges of the main blades on a meridian plane.
